    Certain types of infrastructure--critical infrastructure (CI)--play vital roles in underpinning our economy, security and way of life. These complex and often interconnected systems have become so ubiquitous and essential to day-to-day life that they are easily taken for granted. Often it is only when the important services provided by such infrastructure are interrupted--when we lose easy access to electricity, health care, telecommunications, transportation or water, for example--that we are conscious of our great dependence on these networks and of the vulnerabilities that stem from such dependence. Unfortunately, it must be assumed that many terrorists are all too aware that CI facilities pose high-value targets that, if successfully attacked, have the potential to dramatically disrupt the normal rhythm of society, cause public fear and intimidation, and generate significant publicity. Indeed, revelations emerging at the time of this writing about Al Qaida's efforts to prepare for possible attacks on major financial facilities in New York, New Jersey, and the District of Columbia remind us just how real and immediate such threats to CI may be. Simply being aware that our nation's critical infrastructure presents terrorists with a plethora of targets, however, does little to mitigate the dangers of CI attacks. In order to prevent and preempt such terrorist acts, better understanding of the threats and vulnerabilities relating to critical infrastructure is required. The Center for Nonproliferation Studies (CNS) presents this document as both a contribution to the understanding of such threats and an initial effort at ''operationalizing'' its findings for use by analysts who work on issues of critical infrastructure protection.

    The World Economic Forum regards the threat of cyber attack as one of the top five global risks confronting nations of the world today. Cyber attacks are increasingly targeting the core functions of the economies in nations throughout the world. The threat to attack critical infrastructures, disrupt critical services, and induce a wide range of damage is becoming more difficult to defend against.

    2004-12-14

    Certain types of infrastructure--critical infrastructure (CI)--play vital roles in underpinning our economy, security, and way of life. One particular type of CI--that relating to chemicals--constitutes both an important element of our nation's infrastructure and a particularly attractive set of potential targets. This is primarily because of the large quantities of toxic industrial chemicals (TICs) it employs in various operations and because of the essential economic functions it serves. This study attempts to minimize some of the ambiguities that presently impede chemical infrastructure threat assessments by providing new insight into the key motivational factors that affect terrorist organizations propensity to attack chemical facilities. Prepared as a companion piece to the Center for Nonproliferation Studies August 2004 study--''Assessing Terrorist Motivations for Attacking Critical Infrastructure''--it investigates three overarching research questions: (1) why do terrorists choose to attack chemical-related infrastructure over other targets; (2) what specific factors influence their target selection decisions concerning chemical facilities; and (3) which, if any, types of groups are most inclined to attack chemical infrastructure targets? The study involved a multi-pronged research design, which made use of four discrete investigative techniques to answer the above questions as comprehensively as possible. These include: (1) a review of terrorism and threat assessment literature to glean expert consensus regarding terrorist interest in targeting chemical facilities; (2) the preparation of case studies to help identify internal group factors and contextual influences that have played a significant role in leading some terrorist groups to attack chemical facilities; (3) an examination of data from the Critical Infrastructure Terrorist Incident Catalog (CrITIC) to further illuminate the nature of terrorist attacks against chemical

    Full Text Available The impact of computer and communications systems in recent decades has not bypassed the national security of states in general, and the State of Israel in particular. Most systems in developed societies rely on computer and information infrastructures, and this growing dependence on information and communication technologies means that a blow to computers and information flow processes is liable to disrupt, paralyze, and sometimes even cause substantive physical damage to essential systems. Computer-based capabilities and their near-global ubiquity expose states to harm in cyberspace by various elements, including hostile countries, terrorist organizations, criminal elements, and even individuals driven by personal challenges or anarchist motives. The threat is particularly acute as management, control, and monitoring systems can be disrupted through changes to a computer program, and no physical attack is needed. Thus, it stands to reason that the face of future conflicts will be transformed beyond recognition.

    2015-03-01

    Full Text Available The growing use of information technology, monitoring, and control through computerized control systems, together with the increasing dependence of the free market on products and services supplied through infrastructure (for example, electric power, have increased interdependency between infrastructures. Consequently, an attack on critical infrastructure is liable to have a decisive effect on the functioning of other infrastructures. The interdependence between infrastructures requires those involved in planning a cyber-attack as well as those involved in defending from such attacks to adjust to this reality and prepare accordingly. The article describes the existing models for analyzing interdependence between infrastructures, proposes an analytical framework for describing the interdependence and examines the possibilities at the United States’ disposal should it decide to engage in a cyber-attack.

    There is no doubt that al-Qaida and its affiliates have displayed, and continue to display, an acute interest in attacking targets that are considered to be important components of the infrastructure of the United States. What has not thus far been carried out, however, is an in-depth examination of the basic nature, historical evolution, and present scope of the organization's objectives that might help government personnel develop sound policy recommendations and analytical indicators to assist in detecting and interdicting plots of this nature. This study was completed with the financial support of the Lawrence Livermore National Laboratory, through a project sponsored by the U.S. Department of Homeland Security, Science and Technology Directorate. It is specifically intended to increase counterterrorism analysts understanding of certain features of al-Qaida's strategy and operations in order to facilitate the anticipation and prevention of attacks directed against our most critical infrastructures. The procedure adopted herein has involved consulting a wide variety of source materials that bear on the topic, ranging from sacred religious texts and historical accounts to al-Qaida-linked materials and the firsthand testimony of captured members of the group. It has also intentionally combined multiple approaches, including exploring the more esoteric religion-historical referents that have served to influence al-Qaida's behavior, providing a strategic analysis of its objectives and targeting rationales, closely examining the statements and writings of al-Qaida leaders and spokesmen (in part on the basis of material translated from primary sources), offering a descriptive analysis of its past global attack patterns, and producing concise but nonetheless in-depth case studies of its previous ''infrastructural'' attacks on U.S. soil. The analyses contained herein tend to support the preliminary assessment made by some of the

    The stability of infrastructure network is always a critical issue studied by researchers in different fields. A lot of works have been devoted to reveal the robustness of the infrastructure networks against random and malicious attacks. However, real attack scenarios such as earthquakes and typhoons are instead localised attacks which are investigated only recently. Unlike previous studies, we examine in this paper the resilience of infrastructure networks by focusing on the recovery process from localised attacks. We introduce various preferential repair strategies and found that they facilitate and improve network recovery compared to that of random repairs, especially when population size is uneven at different locations. Moreover, our strategic repair methods show similar effectiveness as the greedy repair. The validations are conducted on simulated networks, and on real networks with real disasters. Our method is meaningful in practice as it can largely enhance network resilience and contribute to network risk reduction.

    Full Text Available The paper explores the notion of cyber attack as a concept for understanding modern conflicts. It starts by elaborating a conceptual theoretical framework, observing that when it comes to cyber attacks, cyber war and cyber defense there are no internationally accepted definitions on the subject, mostly because of the relative recency of the terms. The second part analyzes the cyber realities of recent years, emphasizing the most advertised cyber attacks in the international mass media: Estonia (2007 and Georgia (2008, with a focus on two main lessons learned: how complicated is to define a cyber war and how difficult to defend against it. Crucial implications for world’s countries and the role of NATO in assuring an effective collective cyber defense are analyzed in the third part. The need for the development of strategic cyber defense documents (e.g. NATO Cyber Defense Policy, NATO Strategic Concept is further examined. It is suggested that particular attention should be paid to the development of a procedure for clearly discriminating between events (cyber attacks, cyber war, cyber crime, or cyber terrorism, and to a procedure for the conduct of nation’s legitimate military/civil cyber response operations.

    The need to protect critical electrical infrastructure from terrorist attacks, or other physical damage, including weather related events, or the potential impact of computer viruses and other attacks on IT resources are discussed. Activities of the North American Electric Reliability Council (NERC) are highlighted which seek to safeguard the North American bulk electric power system principally through the Information Sharing and Analysis Sector (ES-ISAC). ES-ISAC serves the electricity sector by facilitating communication between electric sector participants, federal government and other critical infrastructure industries by disseminating threat indications, analyses and warnings, together with interpretations, to assist the industry in taking infrastructure protection actions. Attention is drawn to the numerous cyber incidents in recent years, which although resulted in no loss of service to electricity customers so far, in at least one instance (the January 25th SOL-Slammer worm incident) resulted in degradation of service in a number of sectors, including financial, transportation and telecommunication services. The increasing frequency of cyber-based attacks, coupled with the industry's growing dependence on e-commerce and electronic controls, are good reasons to believe that critical infrastructure protection (CIP) poses a serious challenge to the industry's risk management practices. The Canadian Electricity Association (CEA) is an active participant in ES-ISAC and works cooperatively with a range of partners, such as the Edison Electric Institute and the American Public Power Association to ensure coordination and effective protection program delivery for the electric power sector. The Early Warning System (EWS) developed by the CIP Working Group is one of the results of this cooperation. EWS uses the Internet, e-mail, web-enabled cell phones and Blackberry hand-held devices to deliver real-time threat information to members on a 24/7 basis. EWS

    Full Text Available The paper deals with those infrastructures by which world society, under the pressure ofdemographic explosion, self-survives. The main threatening comes not from terrorist attacks, but fromthe great natural catastrophes and global climate change. It’s not for the first time in history when suchmeasures of self-protection are built up. First objective of this paper is to present the background fordurability analysis. Then, with the aid of these mathematical tools the absolute durability of three linearmodels, typical for critical infrastructures, are successively calculated. In order to enhance the durabilityof critical infrastructures the solution based on redundancies is chosen. Five types of connection theredundancies for each of the three models are considered. Three topological schemes for connecting theredundancies are adopted: locally, by twining and globally. Absolute values of durability in all fifteenmodels with redundancies are further calculated. Then, the relative performances of enhanced durabilityin the same fifteen models, compared with the three original models, considered as references, areanalysed. The relative costs of the same fifteen models and in similar topologic conditions are furtheranalysed. By dividing the performance with cost the relative profitableness of each model is obtained.Finally, the three initial models, each reshaped with redundancies in three selective modes, arecompared from the perspective of their relative profitableness. The outcomes of this paper are original.They are of practical interests in planning the maintenance programs and checking the plausibility ofproposed interventions according to the clause 7.4 of ISO 13822:2001

    The first step in preparing any battlespace is to define the domain for attack and maneuver. The various military service components have directed authority to focus their efforts in specific domains of operations (e.g., naval operations are mainly in the maritime domain). However, cyberspace operations pose challenges because they span multiple operational domains. This paper focuses on U.S. cyberspace policy related to defending and exploiting critical infrastructure assets. Also, it examines the issues involved in delineating responsibility for U.S. defensive and offensive operations related to critical infrastructures.

    Full Text Available Every economy of an advanced nation relies on information systems and interconnected networks, thus in order to ensure the prosperity of a nation, making cyberspace a secure place becomes as crucial as securing society. Cyber security means ensuring the safety of this cyberspace from threats which can take different forms, such as stealing secret information from national companies and government institutions, attacking infrastructure vital for the functioning of the nation or attacking the privacy of the single citizen. The critical information infrastructure (CII represents the indispensable "nervous system", that allow modern societies to work and live. Besides, without it, there would be no distribution of energy, no services like banking or finance, no air traffic control and so on. But at the same time, in the development process of CII, security was never considered a top priority and for this reason they are subject to a high risk in relation to the organized crime.

    2013-01-01

    Many real world complex systems such as infrastructure, communication and transportation networks are embedded in space, where entities of one system may depend on entities of other systems. These systems are subject to geographically localized failures due to malicious attacks or natural disasters. Here we study the resilience of a system composed of two interdependent spatially embedded networks to localized geographical attacks. We find that if an attack is larger than a finite (zero fraction of the system) critical size, it will spread through the entire system and lead to its complete collapse. If the attack is below the critical size, it will remain localized. In contrast, under random attack a finite fraction of the system needs to be removed to initiate system collapse. We present both numerical simulations and a theoretical approach to analyze and predict the effect of local attacks and the critical attack size. Our results demonstrate the high risk of local attacks on interdependent spatially embedd...

  17. On localization attacks against cloud infrastructure

    2013-05-01

    One of the key characteristics of cloud computing is the device and location independence that enables the user to access systems regardless of their location. Because cloud computing is heavily based on sharing resource, it is vulnerable to cyber attacks. In this paper, we investigate a localization attack that enables the adversary to leverage central processing unit (CPU) resources to localize the physical location of server used by victims. By increasing and reducing CPU usage through the malicious virtual machine (VM), the response time from the victim VM will increase and decrease correspondingly. In this way, by embedding the probing signal into the CPU usage and correlating the same pattern in the response time from the victim VM, the adversary can find the location of victim VM. To determine attack accuracy, we investigate features in both the time and frequency domains. We conduct both theoretical and experimental study to demonstrate the effectiveness of such an attack.

    2013-12-01

    Full Text Available The January 2013 attack on the In Amenas natural gas facility drew international attention. However this attack is part of a portrait of energy infrastructure targeting by non-state actors that spans the globe. Data drawn from the Energy Infrastructure Attack Database (EIAD shows that in the last decade there were, on average, nearly 400 annual attacks carried out by armed non-state actors on energy infrastructure worldwide, a figure that was well under 200 prior to 1999. This data reveals a global picture whereby violent non-state actors target energy infrastructures to air grievances, communicate to governments, impact state economic interests, or capture revenue in the form of hijacking, kidnapping ransoms, theft. And, for politically motivated groups, such as those engaged in insurgencies, attacking industry assets garners media coverage serving as a facilitator for international attention. This research note will introduce EIAD and position its utility within various research areas where the targeting of energy infrastructure, or more broadly energy infrastructure vulnerability, has been addressed, either directly or indirectly. We also provide a snapshot of the initial analysis of the data between 1980-2011, noting specific temporal and spatial trends, and then conclude with a brief discussion on the contribution of EIAD, highlighting future research trajectories.

    Assessing the risk of malevolent attacks against large-scale critical infrastructures requires modifications to existing methodologies that separately consider physical security and cyber security. This research has developed a risk assessment methodology that explicitly accounts for both physical and cyber security, while preserving the traditional security paradigm of detect, delay, and respond. This methodology also accounts for the condition that a facility may be able to recover from or mitigate the impact of a successful attack before serious consequences occur. The methodology uses evidence-based techniques (which are a generalization of probability theory) to evaluate the security posture of the cyber protection systems. Cyber threats are compared against cyber security posture using a category-based approach nested within a path-based analysis to determine the most vulnerable cyber attack path. The methodology summarizes the impact of a blended cyber/physical adversary attack in a conditional risk estimate where the consequence term is scaled by a ''willingness to pay'' avoidance approach.

  20. Threat Assessment of Potential Terrorist Attacks to the Transport Infrastructure

    2014-06-01

    Full Text Available The paper presents threat assessment of potential terrorist attacks to the transport infrastructure. The range of transportation infrastructure has spread and includes railway, inland waterways, road, maritime, air, intermodal transport infrastructure and intelligent transport systems (ITS. ITS service is the provision of an ITS application through a well-defined organisational and operational framework with the aim of contributing to the user safety, efficiency, comfort and/or to facilitate or support transport and travel operations. Terrorism means acts of violence committed by groups that view themselves as victimized by some notable historical wrong. Although these groups have no formal connection with governments, they usually have the financial and moral backing of sympathetic governments. Typically, they stage unexpected attacks on civilian targets, including transport infrastructure, with the aim of sowing fear and confusion. Based on the analyses, transportation infrastructure is potentially threatened with terrorism attacks, especially road and rail infrastructure (about 23 %, and to a smaller degree the maritime and air transport infrastructure (about 2 %. There were 90,3% of incidents involve land transport (74,5% – vehicles, 9,5% – buses, 6,3% - rail covered the 41-year period 1967-2007 in the USA. Legal steps to fight terrorism have been taken on the international level, furthermore, some institutions have been established for this purpose.

  1. Vulnerability of critical infrastructures : identifying critical nodes.

    Energy Technology Data Exchange (ETDEWEB)

    Cox, Roger Gary; Robinson, David Gerald

    2004-06-01

    The objective of this research was the development of tools and techniques for the identification of critical nodes within critical infrastructures. These are nodes that, if disrupted through natural events or terrorist action, would cause the most widespread, immediate damage. This research focuses on one particular element of the national infrastructure: the bulk power system. Through the identification of critical elements and the quantification of the consequences of their failure, site-specific vulnerability analyses can be focused at those locations where additional security measures could be effectively implemented. In particular, with appropriate sizing and placement within the grid, distributed generation in the form of regional power parks may reduce or even prevent the impact of widespread network power outages. Even without additional security measures, increased awareness of sensitive power grid locations can provide a basis for more effective national, state and local emergency planning. A number of methods for identifying critical nodes were investigated: small-world (or network theory), polyhedral dynamics, and an artificial intelligence-based search method - particle swarm optimization. PSO was found to be the only viable approach and was applied to a variety of industry accepted test networks to validate the ability of the approach to identify sets of critical nodes. The approach was coded in a software package called Buzzard and integrated with a traditional power flow code. A number of industry accepted test networks were employed to validate the approach. The techniques (and software) are not unique to power grid network, but could be applied to a variety of complex, interacting infrastructures.

    2013-08-01

    Full Text Available Increasingly, our critical infrastructure is managed and controlled by computers and the information networks that connect them. Cyber-terrorists and other malicious actors understand the economic and social impact that a successful attack on these systems could have. While it is imperative that we defend against such attacks, it is equally imperative that we realize how best to react to them. This article presents the strongest-path method of analyzing all potential pathways of exposure to risk – no matter how indirect or circuitous they may be – in a network model of infrastructure and operations. The method makes direct use of expert knowledge about entities and dependency relationships without the need for any simulation or any other models. By using path analysis in a directed graph model of critical infrastructure, planners can model and assess the effects of a potential attack and develop resilient responses.

    Firms cannot function successfully without managing a host of internal and external organizational and process interdependencies. Part of this involves business continuity planning, which directly aects how resilient arm and its business sector are in the face of disruptions. This paper presents the results of eld studies related to information risk management practices in the health care and retail sectors. The studies explore information risk management coordinating signals within and across rms in these sectors as well as the potential eects of cyber disruptions on the rms as stand-alone entities and as part of a critical infrastructure. The health care case study investigates the impact of the Zotob worm on the ability to deliver medical care and treatment.

    In FP7 MARsite project WP9, the integration algorithm of existing strong motion networks with the critical infrastructures strong motion networks have been studied. In Istanbul, the existing Istanbul Earthquake Early Warning (IEEW) strong motion network consists of 15 stations including 10 on land and 5 ocean bottom stations. The system provides continuous online data and earthquake early warning alert depending on the exceedance of the threshold levels in ground motion acceleration in certain number of station within the certain time interval. The data transmission is provided through the fiber optic cable and satellite line alternatively. The early warning alert is transmitted to the critical infrastructures of Istanbul Natural Gas distribution line and Marmaray Tube Tunnel line in order to activate the local strong motion networks for the automatic shut-off mechanism. Istanbul Natural Gas distribution line has 1.800km steel and 15.200km polyethylene in total 18.000km gas pipeline in Istanbul. There are in total 750 district regulators in the city where the gas pressure is reduced from 20bar to 4bar and from there the gas is transmitted with polyethylene lines to service boxes. Currently, Istanbul Natural Gas Distribution Company (IGDAS) has its own strong motion network with 110 strong motion stations installed at the 110 of 750 district regulators. Once the IGDAS strong motion network is activated by the IEEW network, depending on the exceedance of the ground motion parameters threshold levels the gas flow is stopped at the district regulators. Other than the Earthquake Early Warning operation in IGDAS strong motion network, having the calculated ground motion parameters in the network provides damage maps for the buildings and natural gas pipeline network. The Marmaray Tube Tunnel connects the Europe and Asian sides of Istanbul City by a rail line. The tunnel is 1.4km length and consists of 13segments. There is strong motion monitoring network in the tunnel

    Critical Infrastructure control systems continue to foster predictable communication paths, static configurations, and unpatched systems that allow easy access to our nation's most critical assets. This makes them attractive targets for cyber intrusion. We seek to address these attack vectors by automatically randomizing network settings, randomizing applications on the end devices themselves, and dynamically defending these systems against active attacks. Applying these protective measures will convert control systems into moving targets that proactively defend themselves against attack. Sandia National Laboratories has led this effort by gathering operational and technical requirements from Tennessee Valley Authority (TVA) and performing research and development to create a proof-of-concept solution. Our proof-of-concept has been tested in a laboratory environment with over 300 nodes. The vision of this project is to enhance control system security by converting existing control systems into moving targets and building these security measures into future systems while meeting the unique constraints that control systems face.

    A critical infrastructure (CI) can fail with various degrees of severity due to physical and logical vulnerabilities. Since many interdependencies exist between CIs, failures can have dramatic consequences on the entire infrastructure. This paper focuses on threats that affect information and communication systems that constitute the critical information infrastructure (CII). A new collaborative access control framework called PolyOrBAC is proposed to address security problems that are specific to CIIs. The framework offers each organization participating in a CII the ability to collaborate with other organizations while maintaining control of its resources and internal security policy. The approach is demonstrated on a practical scenario involving the electrical power grid.

  14. Decontamination of Anthrax spores in critical infrastructure and critical assets.

    Decontamination of anthrax spores in critical infrastructure (e.g., subway systems, major airports) and critical assets (e.g., the interior of aircraft) can be challenging because effective decontaminants can damage materials. Current decontamination methods require the use of highly toxic and/or highly corrosive chemical solutions because bacterial spores are very difficult to kill. Bacterial spores such as Bacillus anthracis, the infectious agent of anthrax, are one of the most resistant forms of life and are several orders of magnitude more difficult to kill than their associated vegetative cells. Remediation of facilities and other spaces (e.g., subways, airports, and the interior of aircraft) contaminated with anthrax spores currently requires highly toxic and corrosive chemicals such as chlorine dioxide gas, vapor- phase hydrogen peroxide, or high-strength bleach, typically requiring complex deployment methods. We have developed a non-toxic, non-corrosive decontamination method to kill highly resistant bacterial spores in critical infrastructure and critical assets. A chemical solution that triggers the germination process in bacterial spores and causes those spores to rapidly and completely change to much less-resistant vegetative cells that can be easily killed. Vegetative cells are then exposed to mild chemicals (e.g., low concentrations of hydrogen peroxide, quaternary ammonium compounds, alcohols, aldehydes, etc.) or natural elements (e.g., heat, humidity, ultraviolet light, etc.) for complete and rapid kill. Our process employs a novel germination solution consisting of low-cost, non-toxic and non-corrosive chemicals. We are testing both direct surface application and aerosol delivery of the solutions. A key Homeland Security need is to develop the capability to rapidly recover from an attack utilizing biological warfare agents. This project will provide the capability to rapidly and safely decontaminate critical facilities and assets to return them to

    Full Text Available The new dynamics and intensity of the risks and threats posed to societal functioning and citizens’ security have acquired new meanings. Consequently, an integrated approach to the concept of ”critical infrastructure” is necessary. The critical nature of some of the basic characteristics of the critical infrastructures has made them acquire new meanings within the national/transnational strategic planning. Moreover, the complexity and importance of critical infrastructure protection for social stability have generated the correlaton of the strategies developed by states and organizations.

  16. Service Modeling Language Applied to Critical Infrastructure

    Science.gov (United States)

    Baldini, Gianmarco; Fovino, Igor Nai

    The modeling of dependencies in complex infrastructure systems is still a very difficult task. Many methodologies have been proposed, but a number of challenges still remain, including the definition of the right level of abstraction, the presence of different views on the same critical infrastructure and how to adequately represent the temporal evolution of systems. We propose a modeling methodology where dependencies are described in terms of the service offered by the critical infrastructure and its components. The model provides a clear separation between services and the underlying organizational and technical elements, which may change in time. The model uses the Service Modeling Language proposed by the W3 consortium for describing critical infrastructure in terms of interdependent services nodes including constraints, behavior, information flows, relations, rules and other features. Each service node is characterized by its technological, organizational and process components. The model is then applied to a real case of an ICT system for users authentication.

  1. Fuzzy architecture assessment for critical infrastructure resilience

    Energy Technology Data Exchange (ETDEWEB)

    Muller, George

    2012-12-01

    This paper presents an approach for the selection of alternative architectures in a connected infrastructure system to increase resilience of the overall infrastructure system. The paper begins with a description of resilience and critical infrastructure, then summarizes existing approaches to resilience, and presents a fuzzy-rule based method of selecting among alternative infrastructure architectures. This methodology includes considerations which are most important when deciding on an approach to resilience. The paper concludes with a proposed approach which builds on existing resilience architecting methods by integrating key system aspects using fuzzy memberships and fuzzy rule sets. This novel approach aids the systems architect in considering resilience for the evaluation of architectures for adoption into the final system architecture.

    The need to protect national critical infrastructure has led to the development of a threat analysis framework. The threat analysis framework can be used to identify the elements required to quantify threats against critical infrastructure assets and provide a means of distributing actionable threat information to critical infrastructure entities for the protection of infrastructure assets. This document identifies and describes five key elements needed to perform a comprehensive analysis of threat: the identification of an adversary, the development of generic threat profiles, the identification of generic attack paths, the discovery of adversary intent, and the identification of mitigation strategies.

    The presented spatial risk assessment method allows for managing critical network infrastructure in urban areas under abnormal and future conditions caused e.g.,by terrorist attacks,infrastructure deterioration or climate change.For the spatial risk assessment,vulnerability maps for critical network infrastructure are merged with hazard maps for an interfering process.Vulnerability maps are generated using a spatial sensitivity analysis of network transport models to evaluate performance decrease under investigated thread scenarios.Thereby parameters are varied according to the specific impact of a particular threat scenario.Hazard maps are generated with a geographical information system using raster data of the same threat scenario derived from structured interviews and cluster analysis of events in the past.The application of the spatial risk assessment is exemplified by means of a case study for a water supply system,but the principal concept is applicable likewise to other critical network infrastructure.The aim of the approach is to help decision makers in choosing zones for preventive measures.

    The operation of cyber infrastructures relies on both cyber and physical components, which are subject to incidental and intentional degradations of different kinds. Within the context of network and computing infrastructures, we study the strategic interactions between an attacker and a defender using game-theoretic models that take into account both cyber and physical components. The attacker and defender optimize their individual utilities, expressed as sums of cost and system terms. First, we consider a Boolean attack-defense model, wherein the cyber and physical subinfrastructures may be attacked and reinforced as individual units. Second, we consider a component attack-defense model wherein their components may be attacked and defended, and the infrastructure requires minimum numbers of both to function. We show that the Nash equilibrium under uniform costs in both cases is computable in polynomial time, and it provides high-level deterministic conditions for the infrastructure survival. When probabilities of successful attack and defense, and of incidental failures, are incorporated into the models, the results favor the attacker but otherwise remain qualitatively similar. This approach has been motivated and validated by our experiences with UltraScience Net infrastructure, which was built to support high-performance network experiments. The analytical results, however, are more general, and we apply them to simplified models of cloud and high-performance computing infrastructures. PMID:25847370

    Resiliency and security in control systems such as SCADA and Nuclear plant’s in today’s world of hackers and malware are a relevant concern. Computer systems used within critical infrastructures to control physical functions are not immune to the threat of cyber attacks and may be potentially vulnerable. Tailoring an intrusion detection system to the specifics of critical infrastructures can significantly improve the security of such systems. The IDS-NNM – Intrusion Detection System using Neural Network based Modeling, is presented in this paper. The main contributions of this work are: 1) the use and analyses of real network data (data recorded from an existing critical infrastructure); 2) the development of a specific window based feature extraction technique; 3) the construction of training dataset using randomly generated intrusion vectors; 4) the use of a combination of two neural network learning algorithms – the Error-Back Propagation and Levenberg-Marquardt, for normal behavior modeling. The presented algorithm was evaluated on previously unseen network data. The IDS-NNM algorithm proved to be capable of capturing all intrusion attempts presented in the network communication while not generating any false alerts.

    Strategic infrastructure networks include the highly complex and interconnected systems that are so vital to a city or state that any sudden disruption can result in debilitating impacts on human life, the economy and the society as a whole. Recently, various studies have applied complex network-based models to study the performance and vulnerability of infrastructure systems under various types of attacks and hazards - a major part of them is, particularly after the 9/11 incident, related to terrorism attacks. Here, vulnerability is generally defined as the performance drop of an infrastructure system under a given disruptive event. The performance can be measured by different metrics, which correspond to various levels of resilience. In this paper, we will address vulnerability and exposure of critical infrastructure in the Eastern Alps. The Federal State Tyrol is an international transport route and an essential component of the north-south transport connectivity in Europe. Any interruption of the transport flow leads to incommensurable consequences in terms of indirect losses, since the system does not feature redundant elements at comparable economic efficiency. Natural hazard processes such as floods, debris flows, rock falls and avalanches, endanger this infrastructure line, such as large flood events in 2005 or 2012, rock falls 2014, which had strong impacts to the critical infrastructure, such as disruption of the railway lines (in 2005 and 2012), highways and motorways (in 2014). The aim of this paper is to present how critical infrastructures as well as communities and societies are vulnerable and can be resilient against natural hazard risks and the relative cascading effects to different compartments (industrial, infrastructural, societal, institutional, cultural, etc.), which is the dominant by the type of hazard (avalanches, torrential flooding, debris flow, rock falls). Specific themes will be addressed in various case studies to allow cross

  16. Identification and Ranking of Critical Assets within an Electrical Grid under Threat of Cyber Attack

    Science.gov (United States)

    Boyer, Blake R.

    This paper examines the ranking of critical assets within an electrical grid under threat of cyber attack.1 Critical to this analysis is the assumption of zero hour exploits namely, the threat of an immediate attack as soon as a vulnerability is discovered. Modeling shows that over time load fluctuations as well as other system variations will change the importance of each asset in the delivery of bulk power. As opposed to classic stability studies where risk can be shown to be greatest during high load periods, the zero hour exploit-cyber-risk assumes that vulnerabilities will be attacked as soon as they are discovered. The probability of attacks is made uniform over time to include any and all possible attacks. Examining the impact of an attack and how the grid reacts immediately following an attack will identify and determine the criticality of each asset. This work endeavors to fulfill the NERC Critical Infrastructure Protection Requirements CIP-001-1 through CIP-009-2, cyber security requirements for the reliable supply of bulk power to customers throughout North America. 1Critical assets will here refer to facilities, systems, and equipment, which, if destroyed, degraded, or otherwise rendered unavailable, would affect the reliability or operability of the Bulk Electric System, NERC Glossary of Terms Used in Reliability Standards, 2009

    2014-05-01

    This paper presents a solution for visualizing the common operating picture (COP) of the critical infrastructure (CI). The purpose is to improve the situational awareness (SA) of the strategic-level actor and the source system operator in order to support decision making. The information is obtained through the Situational Awareness of Critical Infrastructure and Networks (SACIN) framework. The system consists of an agent-based solution for gathering, storing, and analyzing the information, and a user interface (UI) is presented in this paper. The UI consists of multiple views visualizing information from the CI in different ways. Different CI actors are categorized in 11 separate sectors, and events are used to present meaningful incidents. Past and current states, together with geographical distribution and logical dependencies, are presented to the user. The current states are visualized as segmented circles to represent event categories. Geographical distribution of assets is displayed with a well-known map tool. Logical dependencies are presented in a simple directed graph, and users also have a timeline to review past events. The objective of the UI is to provide an easily understandable overview of the CI status. Therefore, testing methods, such as a walkthrough, an informal walkthrough, and the Situation Awareness Global Assessment Technique (SAGAT), were used in the evaluation of the UI. Results showed that users were able to obtain an understanding of the current state of CI, and the usability of the UI was rated as good. In particular, the designated display for the CI overview and the timeline were found to be efficient.

  2. Prevention of Spoofing Attacks in the Infrastructure Wireless Networks

    2012-01-01

    Full Text Available Problem statement: Spoofing Attack is one of the vulnerabilities in the wireless networks, which is a situation in which the intruder successfully masquerades as legal one. Spoofing Attacks will decrease the performance of the network and violate many security issues. In the networks that use MAC address based filtering approach to authenticate the clients, the spoofer just needs to get a valid MAC address that belong to some authorized client in the network in order to gain an illegitimate advantage. Approach: In this article, it has proposed an algorithm that uses an additional authentication process beside MAC address filtering and periodically re-authenticates the client after sending every specific number of Data frames. The proposed additional authentication process is based on two parts. First: Using unique information that belongs to every client in the network such as computer name, CPU ID and the current time as inputs to a hash function (one-way function, then insert the hash value in the slack fields of the header of the frame (Steganography. Second: Make a modification to the access point access control list by adding that unique information belong to each client in addition to its MAC address in the access control list. Thus, when the AP receives an Authentication frame from a client, it will first check the MAC address, if it is legal; the AP will re-compute the Hash value depending on the corresponding identifiers stored in the access control list and the time of creating the frame, then compare the resulted hash value with the received one and decide whether to reject or accept the access. Results: The results has been found is that even the attacker is spoofed the MAC address; he/she cannot communicate with the network because the attacker will fail in computing the hash value that depends on the Computer name and CPU ID. Also the attacker will be prevented even if he/she enters the network after the legal client finished the

    International audience Due to physical and logical vulnerabilities, a critical infrastructure (CI) can encounter failures of various degrees of severity, and since there are many interdependencies between CIs, simple failures can have dramatic consequences on the users. In this paper, we mainly focus on malicious threats that might affect the information and communication system that controls the Critical Infrastructure, i.e., the Critical Information Infrastructure (CII). To address the s...

    The constant technological evolution in Computer Vision enabled the development of new techniques which in conjunction with the use of Unmanned Aerial Vehicles (UAVs) may extract high quality photogrammetric products for several applications. Dense Image Matching (DIM) is a Computer Vision technique that can generate a dense 3D point cloud of an area or object. The use of UAV systems and DIM techniques is not only a flexible and attractive solution to produce accurate and high qualitative photogrammetric results but also is a major contribution to cost effectiveness. In this context, this study aims to highlight the benefits of the use of the UAVs in critical infrastructure monitoring applying DIM. A Multi-View Stereo (MVS) approach using multiple images (RGB digital aerial and oblique images), to fully cover the area of interest, is implemented. The application area is an Olympic venue in Attica, Greece, at an area of 400 acres. The results of our study indicate that the UAV+DIM approach respond very well to the increasingly greater demands for accurate and cost effective applications when provided with, a 3D point cloud and orthomosaic.

    2014-01-01

    The paper outlines a bioinspired approach named "network nervous system" and methods of simulation of infrastructure attacks and protection mechanisms based on this approach. The protection mechanisms based on this approach consist of distributed procedures of information collection and processing, which coordinate the activities of the main devices of a computer network, identify attacks, and determine necessary countermeasures. Attacks and protection mechanisms are specified as structural models using a set-theoretic approach. An environment for simulation of protection mechanisms based on the biological metaphor is considered; the experiments demonstrating the effectiveness of the protection mechanisms are described.

  8. A fault diagnosis system for interdependent critical infrastructures based on HMMs

    International Nuclear Information System (INIS)

    Modern society depends on the smooth functioning of critical infrastructures which provide services of fundamental importance, e.g. telecommunications and water supply. These infrastructures may suffer from faults/malfunctions coming e.g. from aging effects or they may even comprise targets of terrorist attacks. Prompt detection and accommodation of these situations is of paramount significance. This paper proposes a probabilistic modeling scheme for analyzing malicious events appearing in interdependent critical infrastructures. The proposed scheme is based on modeling the relationship between datastreams coming from two network nodes by means of a hidden Markov model (HMM) trained on the parameters of linear time-invariant dynamic systems which estimate the relationships existing among the specific nodes over consecutive time windows. Our study includes an energy network (IEEE 30 model bus) operated via a telecommunications infrastructure. The relationships among the elements of the network of infrastructures are represented by an HMM and the novel data is categorized according to its distance (computed in the probabilistic space) from the training ones. We considered two types of cyber-attacks (denial of service and integrity/replay) and report encouraging results in terms of false positive rate, false negative rate and detection delay. - Highlights: • An HMM-based scheme is proposed for analyzing malicious events in critical infrastructures. • We use the IEEE 30 model bus operated via an emulated ICT infrastructure. • Novel data is categorized based on its probabilistic distance from the training one. • We considered two types of cyber-attacks and report results of extensive experiments

    Modern critical infrastructure networks are becoming increasingly interdependent where the failures in one network may cascade to other dependent networks, causing severe widespread national-scale failures. A number of previous efforts have been made to analyze the resiliency and robustness of interdependent networks based on different models. However, communication network, which plays an important role in today's infrastructures to detect and handle failures, has attracted little attention in the interdependency studies, and no previous models have captured enough practical features in the critical infrastructure networks. In this paper, we study the interdependencies between communication network and other kinds of critical infrastructure networks with an aim to identify vulnerable components and design resilient communication networks. We propose several interdependency models that systematically capture various features and dynamics of failures spreading in critical infrastructure networks. We also discuss several research challenges in building reliable communication solutions to handle failures in these models.

  10. Toward Developing Genetic Algorithms to Aid in Critical Infrastructure Modeling

    Energy Technology Data Exchange (ETDEWEB)

    2007-05-01

    Today’s society relies upon an array of complex national and international infrastructure networks such as transportation, telecommunication, financial and energy. Understanding these interdependencies is necessary in order to protect our critical infrastructure. The Critical Infrastructure Modeling System, CIMS©, examines the interrelationships between infrastructure networks. CIMS© development is sponsored by the National Security Division at the Idaho National Laboratory (INL) in its ongoing mission for providing critical infrastructure protection and preparedness. A genetic algorithm (GA) is an optimization technique based on Darwin’s theory of evolution. A GA can be coupled with CIMS© to search for optimum ways to protect infrastructure assets. This includes identifying optimum assets to enforce or protect, testing the addition of or change to infrastructure before implementation, or finding the optimum response to an emergency for response planning. This paper describes the addition of a GA to infrastructure modeling for infrastructure planning. It first introduces the CIMS© infrastructure modeling software used as the modeling engine to support the GA. Next, the GA techniques and parameters are defined. Then a test scenario illustrates the integration with CIMS© and the preliminary results.

    2012-01-01

    Space-based systems play an important role within national critical infrastructures. They are being integrated into advanced air-traffic management applications, rail signalling systems, energy distribution software etc. Unfortunately, the end users of communications, location sensing and timing applications often fail to understand that these infrastructures are vulnerable to a wide range of security threats. The following pages focus on concerns associated with potential cyber-attacks. These are important because future attacks may invalidate many of the safety assumptions that support the provision of critical space-based services. These safety assumptions are based on standard forms of hazard analysis that ignore cyber-security considerations This is a significant limitation when, for instance, security attacks can simultaneously exploit multiple vulnerabilities in a manner that would never occur without a deliberate enemy seeking to damage space based systems and ground infrastructures. We address this concern through the development of a combined safety and security risk assessment methodology. The aim is to identify attack scenarios that justify the allocation of additional design resources so that safety barriers can be strengthened to increase our resilience against security threats.

    Critical infrastructure control systems face many challenges entering the 21st century, including natural disasters, cyber attacks, and terrorist attacks. Revolutionary change is required to solve many existing issues, including gaining greater situational awareness and resiliency through embedding modeling and advanced control algorithms in smart sensors and control devices instead of in a central controller. To support design, testing, and component analysis, a flexible simulation and modeling capability is needed. Researchers at Idaho National Laboratory are developing and evaluating such a capability through their CIPRsim modeling and simulation framework.

    Kaminsky, Dan; Patterson, Meredith L.; Sassaman, Len

    Research unveiled in December of 2008 [15] showed how MD5's long-known flaws could be actively exploited to attack the real-worldCertification Authority infrastructure. In this paper, we demonstrate two new classes of collision, which will be somewhat trickier to address than previous attacks against X.509: the applicability of MD2 preimage attacks against the primary root certificate for Verisign, and the difficulty of validating X.509 Names contained within PKCS#10 Certificate Requests.We also draw particular attention to two possibly unrecognized vectors for implementation flaws that have been problematic in the past: the ASN.1 BER decoder required to parsePKCS#10, and the potential for SQL injection fromtext contained within its requests. Finally, we explore why the implications of these attacks are broader than some have realized - first, because Client Authentication is sometimes tied to X.509, and second, because Extended Validation certificates were only intended to stop phishing attacks from names similar to trusted brands. As per the work of Adam Barth and Collin Jackson [4], EV does not prevent an attacker who can synthesize or acquire a "low assurance" certificate for a given name from acquiring the "green bar" EV experience.

    This report describes a workshop on self-healing infrastructures conducted jointly by Sandia National Laboratories, Infrastructure & Information Division, and the Massachusetts Institute of Technology, Engineering Systems Division. The workshop was held in summer, 2002 and funded under Laboratory-Directed Research and Development (LDRD) No.5 1540. The purpose of the workshop was to obtain a working definition of a self-healing infrastructure, explore concepts for self-healing infrastructures systems, and to propose engineering studies that would lay the foundation for the realization of such systems. The workshop produced a number of useful working documents that clarified the concept of self-healing applied to large-scale system-of-systems exemplified by the US National Critical Infrastructure. The workshop eventually resulted in a joint proposal to the National Science Foundation and a continuing collaboration on intelligent agent based approaches to coordination of infrastructure systems in a self-healing regime.

  6. Critical Infrastructure Interdependency Modeling: A Survey of U.S. and International Research

    Energy Technology Data Exchange (ETDEWEB)

    2006-08-01

    The Nation’s health, wealth, and security rely on the production and distribution of certain goods and services. The array of physical assets, processes, and organizations across which these goods and services move are called "critical infrastructures".1 This statement is as true in the U.S. as in any country in the world. Recent world events such as the 9-11 terrorist attacks, London bombings, and gulf coast hurricanes have highlighted the importance of stable electric, gas and oil, water, transportation, banking and finance, and control and communication infrastructure systems. Be it through direct connectivity, policies and procedures, or geospatial proximity, most critical infrastructure systems interact. These interactions often create complex relationships, dependencies, and interdependencies that cross infrastructure boundaries. The modeling and analysis of interdependencies between critical infrastructure elements is a relatively new and very important field of study. The U.S. Technical Support Working Group (TSWG) has sponsored this survey to identify and describe this current area of research including the current activities in this field being conducted both in the U.S. and internationally. The main objective of this study is to develop a single source reference of critical infrastructure interdependency modeling tools (CIIMT) that could be applied to allow users to objectively assess the capabilities of CIIMT. This information will provide guidance for directing research and development to address the gaps in development. The results will inform researchers of the TSWG Infrastructure Protection Subgroup of research and development efforts and allow a more focused approach to addressing the needs of CIIMT end-user needs. This report first presents the field of infrastructure interdependency analysis, describes the survey methodology, and presents the leading research efforts in both a cumulative table and through individual datasheets.

  11. Development of the efficient emergency preparedness system for the nuclear critical infrastructure

    International Nuclear Information System (INIS)

    The evaluation of the critical nuclear infrastructure vulnerability to threats like human occurrences, terrorist attacks and natural disasters and the preparation of emergency response plans with the estimation of optimized costs are of the vital importance for the assurance of a safe nuclear facilities operation and the national security. In the past national emergency systems did not include vulnerability assessments of the critical nuclear infrastructure as the important part of the comprehensive preparedness framework. The fundamental aims of the efficient emergency preparedness and response system are to provide a sustained emergency readiness and to prevent an emergency situation and accidents. But when an event happens the mission is to mitigate consequences and to protect the people and environment against the nuclear and radiological damage. The efficient emergency response system, which would be activated in the case of the nuclear and/or radiological emergency and release of the radioactivity to the environment, is an important element of a comprehensive system of the nuclear and radiation safety. In the article the new methodology for the critical nuclear infrastructure vulnerability assessment as a missing part of an efficient emergency preparedness system is presented. It can help the overall national energy sectors to identify and better understand the terrorist threats and vulnerabilities of their critical infrastructure. The presented methodology could also facilitate national agencies to develop and implement a vulnerability awareness and education programs for their critical assets to enhance the security, reliability and safe operation of the whole energy infrastructure. The vulnerability assessment methodology will also assist nuclear power plants to develop, validate, and disseminate the assessment and survey of new efficient countermeasures. The significant benefits of the new vulnerability assessment research are to increase nuclear power

  12. A reference model for model-based design of critical infrastructure protection systems

    2015-05-01

    Today's war field environment is getting versatile as the activities of unconventional wars such as terrorist attacks and cyber-attacks have noticeably increased lately. The damage caused by such unconventional wars has also turned out to be serious particularly if targets are critical infrastructures that are constructed in support of banking and finance, transportation, power, information and communication, government, and so on. The critical infrastructures are usually interconnected to each other and thus are very vulnerable to attack. As such, to ensure the security of critical infrastructures is very important and thus the concept of critical infrastructure protection (CIP) has come. The program to realize the CIP at national level becomes the form of statute in each country. On the other hand, it is also needed to protect each individual critical infrastructure. The objective of this paper is to study on an effort to do so, which can be called the CIP system (CIPS). There could be a variety of ways to design CIPS's. Instead of considering the design of each individual CIPS, a reference model-based approach is taken in this paper. The reference model represents the design of all the CIPS's that have many design elements in common. In addition, the development of the reference model is also carried out using a variety of model diagrams. The modeling language used therein is the systems modeling language (SysML), which was developed and is managed by Object Management Group (OMG) and a de facto standard. Using SysML, the structure and operational concept of the reference model are designed to fulfil the goal of CIPS's, resulting in the block definition and activity diagrams. As a case study, the operational scenario of the nuclear power plant while being attacked by terrorists is studied using the reference model. The effectiveness of the results is also analyzed using multiple analysis models. It is thus expected that the approach taken here has some merits

  13. Risk analysis of critical infrastructures emphasizing electricity supply and interdependencies

    International Nuclear Information System (INIS)

    Failures in critical infrastructures can cause major damage to society. Wide-area interruptions (blackouts) in the electricity supply system have severe impacts on societal critical functions and other critical infrastructures, but there is no agreed-upon framework on how to analyze and predict the reliability of electricity supply. Thus, there is a need for an approach to cross-sector risk analyses, which facilitates risk analysis of outages in the electricity supply system and enables investigation of cascading failures and consequences in other infrastructures. This paper presents such an approach, which includes contingency analysis (power flow) and reliability analysis of power systems, as well as use of a cascade diagram for investigating interdependencies. A case study was carried out together with the Emergency Preparedness Group in the city of Oslo, Norway and the network company Hafslund Nett. The case study results highlight the need for cross-sector analyses by showing that the total estimated societal costs are substantially higher when cascading effects and consequences to other infrastructures are taken into account compared to only considering the costs of electricity interruptions as seen by the network company. The approach is a promising starting point for cross-sector risk analysis of electricity supply interruptions and consequences for dependent infrastructures.

  14. Optimal recovery sequencing for critical infrastructure resilience assessment.

    2010-09-01

    Critical infrastructure resilience has become a national priority for the U. S. Department of Homeland Security. System resilience has been studied for several decades in many different disciplines, but no standards or unifying methods exist for critical infrastructure resilience analysis. This report documents the results of a late-start Laboratory Directed Research and Development (LDRD) project that investigated the identification of optimal recovery strategies that maximize resilience. To this goal, we formulate a bi-level optimization problem for infrastructure network models. In the 'inner' problem, we solve for network flows, and we use the 'outer' problem to identify the optimal recovery modes and sequences. We draw from the literature of multi-mode project scheduling problems to create an effective solution strategy for the resilience optimization model. We demonstrate the application of this approach to a set of network models, including a national railroad model and a supply chain for Army munitions production.

  20. Identification of critical locations across multiple infrastructures for terrorist actions

    International Nuclear Information System (INIS)

    This paper presents a possible approach to ranking geographic regions that can influence multiple infrastructures. Once ranked, decision makers can determine whether these regions are critical locations based on their susceptibility to terrorist acts. We identify these locations by calculating a value for a geographic region that represents the combined values to the decision makers of all the infrastructures crossing through that region. These values, as well as the size of the geographic region, are conditional on an assumed destructive threat of a given size. In our case study, the threat is assumed to be minor, e.g., a bomb that can affect objects within 7 m of it. This approach first requires an assessment of the users of the system. During this assessment, each user is assigned a performance index (PI) based on the disutility of the loss of each infrastructure's resource via multi-attribute utility theory (MAUT). A Monte Carlo network analysis is then performed to develop importance measures (IM) for the elements of each infrastructure for their ability to service each user. We combine the IMs with the user PIs to a value that we call valued worth (VW) for each infrastructure's elements independently. Then we use spatial analysis techniques within a geographic information system (GIS) to combine the VWs of each infrastructure's elements in a geographic area, conditional on the threat, into a total value we call geographic valued worth (GVW). The GVW is displayed graphically in the GIS system in a color scheme that shows the numerical ranking of these geographic areas. The map and rankings are then submitted to the decision makers to better allocate anti-terrorism resources. A case study of this methodology is performed on the Massachusetts Institute of Technology (MIT) campus. The results of the study show how the methodology can bring attention to areas that are important when several infrastructures are considered, but may be ignored when infrastructures

    Terrorists and criminals more and more attack and destroy important infrastructures like routes, railways, bridges, tunnels, dikes and dams, important buildings. Therefore, reliable on-line and long-term monitoring systems are required to protect such critical infrastructures. Fiber optic sensors are well-suited for that. They can be installed over many kilometers and are able to measure continuously distributed strain, pressure, temperature and further mechanical and physical quantities. The very tiny optical fibers can be integrated into structures and materials and can provide information about any significant changes or damages of the structures. These so-called smart materials and smart structures are able to monitor itself or its environment. Particularly smart technical textiles with embedded fiber optic sensors have become very attractive because of their high importance for the structural health monitoring of geotechnical and masonry infrastructures. Such textiles are usually used for reinforcement of the structures; the embedded fiber optic sensors provide information about the condition of the structures and detect the presence of any damages and destructions in real time. Thus, critical infrastructures can be preventively protected. The paper will introduce this innovative field and will present the results achieved within several German and European projects.

    The projected increases in exposure to multiple climate hazards in many regions of Europe, emphasize the relevance of a multi-hazard risk assessment to comprehensively quantify potential impacts of climate change and develop suitable adaptation strategies. In this context, quantifying the future impacts of climatic extremes on critical infrastructures is crucial due to their key role for human wellbeing and their effects on the overall economy. Critical infrastructures describe the existing assets and systems that are essential for the maintenance of vital societal functions, health, safety, security, economic or social well-being of people, and the disruption or destruction of which would have a significant impact as a result of the failure to maintain those functions. We assess the direct damages of heat and cold waves, river and coastal flooding, droughts, wildfires and windstorms to energy, transport, industry and social infrastructures in Europe along the 21st century. The methodology integrates in a coherent framework climate hazard, exposure and vulnerability components. Overall damage is expected to rise up to 38 billion €/yr, ten time-folds the current climate damage, with drastic variations in risk scenarios. Exemplificative are drought and heat-related damages that could represent 70% of the overall climate damage in 2080s versus the current 12%. Many regions, prominently Southern Europe, will likely suffer multiple stresses and systematic infrastructure failures due to climate extremes if no suitable adaptation measures will be taken.

  4. Concepts to Analyze the Vulnerability of Critical Infrastructures - Taking into account Cybernetics

    Directory of Open Access Journals (Sweden)

    2010-02-01

    Full Text Available Critical Infrastructures (CIs are complex systems. For their operations, these infrastructures are increasingly using Supervisory Control And Data Acquisition (SCADA systems. Management practices are therefore highly dependent on the cyber tools, but also on the data needed to make these tools work. Therefore, CIs are greatly vulnerable to degradation of data. In this context, this paper aims at presenting the fundamentals of a method for analyzing the vulnerabilities of CIs towards the use of cyber data. By characterizing cyber vulnerability of CIs, it will be possible to improve the resilience of these networks and to foster a proactive approach to risk management not only by considering cybernetics from a cyber-attack point of view but also by considering the consequences of the use of corrupted data.

  5. Ontario-U.S. power outages : impacts on critical infrastructure

    International Nuclear Information System (INIS)

    This paper described the power outage and resulting blackout that occurred on August 14, 2003 and identified how critical infrastructure was directly and interdependently impacted in Canada. The aim of the paper was to assist critical infrastructure protection and emergency management professionals in assessing the potential impacts of large-scale critical infrastructure disruptions. Information for the study was acquired from Canadian and American media reports and cross-sectoral information sharing with provincial and federal governments and the private sector. The blackout impacted most of the sources and means of generating, transmitting and distributing power within the area, which in turn impacted all critical infrastructure sectors. Landline and cellular companies experienced operational difficulties, which meant that emergency responders were impacted. Newspapers and the electronic media struggled to release information to the public. The banking and finance industry experienced an immediate degradation of services. The power outage caused shipping and storage difficulties for commercial retailers and dairy producers. A number of incidents were reported where only partially treated waste water was released into neighbouring waterways. The timing of the blackout coincided with the closures of workplaces and created additional difficulties on transportation networks. Many gas station pumps were inoperable. Police, fire departments and ambulance services experienced a dramatic increase in the volume of calls received, and all branches of the emergency services sector encountered transportation delays and difficulties with communications equipment. Nuclear reactors were also impacted. An estimated 150,000 Government of Canada employees were unable to report to work. Estimates have indicated that the power outage cost Ontario's economy between $1 and $2 billion. The outage negatively impacted 82 per cent of small businesses in Ontario. 170 refs., 3 figs

    This paper applies the competing theories of High Reliability Organizations (HRO and Normal Accidents Theory (NAT, two competing views of risk management in highly-complex and tightly-coupled systems, in analyzing the 1998 Ice Storm and the 2003 Blackout to examine vulnerabilities in North America’s critical energy infrastructure (CEI. Inferences are then made by highlighting the similarities and differences in the two cases, which are then used to draw lessons for public managers regarding the protection of CEIs.

     

    As CEIs are highly-complex and tightly-coupled systems, failures stemming from complex and uncertain risks are inevitable. There is an increasingly low tolerance for failure in energy infrastructure because society’s critical infrastructures have become increasingly interdependent. Public managers must regulate CEIs in order to ensure an emphasis is placed on safety and security while also finding ways to reduce unnecessary complexities. It is through the adoption of such measures that public managers will aid in minimizing the cascading effects of inevitable failures.

     

  7. Critical infrastructure: impacts of natural hazards and consequences

    Science.gov (United States)

    Petrova, Elena

    2014-05-01

    Critical infrastructure such as oil and gas pipelines, transmission facilities, heat-, and water supply, lines of communications, roads, railways as well as air and water transport play the key role in social and economic development of every country. Therefore, accidents causing failures and breakdowns of critical infrastructure facilities have the most drastic consequences for the society, economy, and environment. For example, road accidents cause the highest number of fatalities and injuries all over the world, especially in the middle-income countries. The so-called "blackouts" or accidental losses of electric power and power outages entail serious social troubles and heavy economic losses. The pipeline ruptures and oil-tanker crashes accompanied by oil releases cause the most severe environmental and large material damages. Critical infrastructure facilities are most vulnerable to the impacts of natural hazards that trigger many accidents in them especially in the regions most at natural risk. The Russian Federation has more than 2.6 million km of transmission facilities, 940,000 km of roads, 102,000 km of inland waterways, 86,000 km of railways, and more than 70,000 km of trunk pipelines. Many facilities are beyond of their service life and need reconstruction. A very high level of deterioration and "human factor" are the main cause of accidents, ruptures, and crashes. However, natural hazards and disasters also play an essential (sometimes a leading) role in triggering or magnifying accidents in these objects. Thus, natural factors cause more than 70 percent of all "blackouts", about 20 percent of accidents at heat- and water supply systems and water accidents, five percent of pipeline ruptures, and about two to three percent of air crashes, road, and railway accidents. The influence of natural factors is stronger in the North-Western and Central parts of the European Russia, in Krasnodarsky Territory (South of Russia) and in Far East that are more exposed

  8. Enabling software defined networking experiments in networked critical infrastructures

    2014-05-01

    Full Text Available Nowadays, the fact that Networked Critical Infrastructures (NCI, e.g., power plants, water plants, oil and gas distribution infrastructures, and electricity grids, are targeted by significant cyber threats is well known. Nevertheless, recent research has shown that specific characteristics of NCI can be exploited in the enabling of more efficient mitigation techniques, while novel techniques from the field of IP networks can bring significant advantages. In this paper we explore the interconnection of NCI communication infrastructures with Software Defined Networking (SDN-enabled network topologies. SDN provides the means to create virtual networking services and to implement global networking decisions. It relies on OpenFlow to enable communication with remote devices and has been recently categorized as the “Next Big Technology”, which will revolutionize the way decisions are implemented in switches and routers. Therefore, the paper documents the first steps towards enabling an SDN-NCI and presents the impact of a Denial of Service experiment over traffic resulting from an XBee sensor network which is routed across an emulated SDN network.

  9. Anti-social networking: crowdsourcing and the cyber defence of national critical infrastructures.

    Science.gov (United States)

    Johnson, Chris W

    2014-01-01

    We identify four roles that social networking plays in the 'attribution problem', which obscures whether or not cyber-attacks were state-sponsored. First, social networks motivate individuals to participate in Distributed Denial of Service attacks by providing malware and identifying potential targets. Second, attackers use an individual's social network to focus attacks, through spear phishing. Recipients are more likely to open infected attachments when they come from a trusted source. Third, social networking infrastructures create disposable architectures to coordinate attacks through command and control servers. The ubiquitous nature of these architectures makes it difficult to determine who owns and operates the servers. Finally, governments recruit anti-social criminal networks to launch attacks on third-party infrastructures using botnets. The closing sections identify a roadmap to increase resilience against the 'dark side' of social networking.

  10. Entropy as a metric in critical infrastructure situational awareness

    Science.gov (United States)

    Klemetti, Markus; Puuska, Samir; Vankka, Jouko

    2016-05-01

    In this paper, we expand our previously proposed critical infrastructure (CI) model with time dependent stochastic elements. In the model, CI is presented as a directed graph where each vertex represents a discrete system and directed edges dependency relations between the systems. Each node is associated with a finite state machine (FSM) which represents the operational status of the system in question. In this paper we associate a probability distribution to each FSM, which accounts for the flow of time and previous confirmed sensor reading. As time passes, the uncertainty about the state of the system increases. By relying on statistical probabilities that have been previously observed or known, it is possible to make predictions about the current state of CI. We present a dependency graph modelling a subset of Finnish electric grid and mobile networks. CI components are modelled using FSM structure augmented by probabilistic elements for entropy-based calculations. The proposed model provides an estimate about the state of the critical infrastructure when only limited information is available, while taking into account the increasing uncertainty created by the passage of time.

    2008-03-28

    The examination of which protective measures are the most appropriate to be implemented in order to prevent, protect against, respond to, and recover from attacks on critical infrastructures and key resources typically involves a comparison of the consequences that could occur when the protective measure is implemented to those that could occur when it is not. This report describes a framework for evaluation that provides some additional capabilities for comparing optional protective measures. It illustrates some potentially important time-dependent factors, such as the implementation rate, that affect the relative pros and cons associated with widespread implementation of protective measures. It presents example results from the use of protective measures, such as detectors and pretrained responders, for an illustrative biological incident. Results show that the choice of an alternative measure can depend on whether or not policy and financial support can be maintained for extended periods of time. Choice of a time horizon greatly influences the comparison of alternatives.

  14. Critical Infrastructure Surveillance Using SecureWireless Sensor Networks

    Directory of Open Access Journals (Sweden)

    Michael Niedermeier

    2015-11-01

    Full Text Available In this work, a secure wireless sensor network (WSN for the surveillance, monitoring and protection of critical infrastructures was developed. To guarantee the security of the system, the main focus was the implementation of a unique security concept, which includes both security on the communication level, as well as mechanisms that ensure the functional safety during its operation. While there are many theoretical approaches in various subdomains of WSNs—like network structures, communication protocols and security concepts—the construction, implementation and real-life application of these devices is still rare. This work deals with these aforementioned aspects, including all phases from concept-generation to operation of a secure wireless sensor network. While the key focus of this paper lies on the security and safety features of the WSN, the detection, localization and classification capabilities resulting from the interaction of the nodes’ different sensor types are also described.

  15. Federated Modelling and Simulation for Critical Infrastructure Protection

    Science.gov (United States)

    Rome, Erich; Langeslag, Peter; Usov, Andrij

    Modelling and simulation is an important tool for Critical Infrastructure (CI) dependency analysis, for testing methods for risk reduction, and as well for the evaluation of past failures. Moreover, interaction of such simulations with external threat models, e.g., a river flood model, or economic models enable consequence analysis and thus may assist in what-if decision-making processes. The simulation of complex scenarios involving several different CI sectors requires the usage of heterogeneous federated simulations of CIs. However, common standards for modelling and interoperability of such federated CI simulations are missing. Also, creating the required abstract models from CIs and other data, setting up the individual federate simulators and integrating all subsystems is a time-consuming and complicated task that requires substantial know-how and resources. In this chapter, we outline applications and benefit of federated modelling, simulation and analysis (MS&A) for Critical Infrastructure Protection (CIP). We review the state of the art in federated MS&A for CIP and categorise common approaches and interoperability concepts like central and lateral coupling of simulators. As examples for the latter two concepts, we will present in more detail an interoperability standard from the military domain, HLA, and an approach developed in the DIESIS project. Special emphasis will also be put on describing the problem of synchronising systems with different time models. Also, we will briefly assess the state of transferring MS&A for CIP research results to practical application by comparing the situations in the USA and in Europe.

This exceptional performance is a clear sign of the high quality work done by the CMS Infrastructures unit and its supporting teams. Powering infrastructure At the end of March, the EN/EL group observed a problem with the CMS 48 V system. The problem was a lack of isolation between the negative (return) terminal and earth. Although at that moment we were not seeing any loss of functionality, in the long term it would have led to severe disruption to the CMS power system. The 48 V system is critical to the operation of CMS: in addition to feeding the anti-panic lights, essential for the safety of the underground areas, it powers all the PLCs (Twidos) that control AC power to the racks and front-end electronics of CMS. A failure of the 48 V system would bring down the whole detector and lead to evacuation of the cavern. EN/EL technicians have made an accurate search of the fault, ...

The first discussed the application of novel instrumentation, surface and airborne remote sensing techniques, as well as data processing oriented to both detection and characterization of archaeological buried remains and conservation of cultural heritage (Eppelbaum et al 2010). The second stressed the importance of an integrated and multiscale approach for the study and conservation of architectural, archaeological and artistic heritage, from SAR to GPR to imaging based diagnostic techniques (Masini and Soldovieri 2011). The third enlarged the field of analysis to civil engineering structures and infrastructures, providing an overview of the effectiveness and the limitations of single diagnostic techniques, which can be overcome through the integration of different methods and technologies and/or the use of robust and novel data processing techniques (Masini et al 2012). As a whole, the special issue put in evidence the factors that affect the choice of diagnostic strategy, such as the material, the spatial characteristics of the objects or sites, the value of the objects to be investigated (cultural or not), the aim of the investigation (knowledge, conservation, restoration) and the issues to be addressed (monitoring, decay assessment). In order to complete the overview of the application fields of sensing technologies this issue has been dedicated to monitoring of cultural heritage and critical infrastructures to address safety and security issues.

    Full Text Available In the past two years, a number of European countries, members of EU, Australia and Canada have initiated substantive actions in PIC area, establishing bodies responsible, defining procedures and methodologies, allocating significant resources to protect critical infrastructure considered essential or vital. The security concept, and implicit, the economical and energetic ones have different use and defining in relation to the history and organizational culture of every nation. A decisive contribution in the process of defining those concepts is identifying the set of values and national interests, elements that usually are the result of the public opinion perception. The increased share of non-military risks and threats has determined the national security management reconsideration, becoming more obvious the necessity of “public-private partnership” approach. Anew concept is becoming more and more present and gains maximum generality significations. This kind of process reconfigures the position and the role of social state actors: the political class, thebusiness and scientific environment, civil society and citizens.

    2012-04-01

    Full Text Available Critical infrastructure systems (CISs, such as power grids, transportation systems, communication networks and water systems are the backbone of a country’s national security and industrial prosperity. These CISs execute large numbers of workflows with very high resource requirements that can span through different systems and last for a long time. The proper functioning and synchronization of these workflows is essential since humanity’s well-being is connected to it. Because of this, the challenge of ensuring availability and reliability of these services in the face of a broad range of operating conditions is very complicated. This paper proposes an architecture which dynamically executes a scheduling algorithm using feedback about the current status of CIS nodes. Different artificial neural networks (ANNs were created in order to solve the scheduling problem. Their performances were compared and as the main result of this paper, an optimal ANN architecture for workflow scheduling in CISs is proposed. A case study is shown for a meter data management system with measurements from a power distribution management system in Serbia. Performance tests show that significant improvement of the overall execution time can be achieved by ANNs.

    Virtual Observatories can provide access to vast stores of scientific data: observations and models as well as services to analyze, visualize and assimilate multiple data sources. As these electronic resource become widely used, there is potential to improve the efficiency, interoperability, collaborative potential, and impact of a wide range of interdisciplinary scientific research. In addition, we know that as the diversity of collaborative science and volume of accompanying data and data generators/consumers grows so do the challenges. In order for Virtual Observatories to realize their potential and become indispensible infrastructure, social, political and technical challenges need to be addressed concerning (at least) roles and responsibilities, data and services policies, representations and interoperability of services, data search, access, and usability. In this presentation, we discuss several concepts and instances of the Virtual Observatory and related projects that may, and may not, be meeting the abovementioned challanges. We also argue that science driven needs and architecture development are critical in the development of sustainable (and thus agile) cyberinfrastructure. Finally we some present or emerging candidate technologies and organizational constructs that will need to be pursued.

    2015-05-01

    Full Text Available The massive data leaks by Wikileaks suggest how fragile a national security is from the perspective of information system and network sustainability. What Wikileaks have done and achieved raises some causes of concern. How do we view such leaks? Are they an act of whistle-blowing or disclosure of government misconduct in the interest of the public? Are they the champion of free press? Or are they a form of data breach or information security attack? What if it involves the critical information infrastructure (CII? Could they be classified as ‘cyber-terrorist’? The objective this paper is to outline the problems and challenges that Malaysia should anticipate and address in maintaining its national CII. The paper first looks at Wikileaks as it is the ‘icon’ of data leaks. Then it examines the causes of data breach before proceeding to foray into the concept of ‘critical information infrastructure’ in the US and Malaysia. Finally, the paper explores legal options that Malaysia can adopt in preparing herself to possible data breaches onslaught. It is the contention of the paper that the existing traditional legal framework should be reformed in line with the advances of the information and communications technologies, especially in light of the onslaught of data leaks by the new media typically represented by Wikileaks.

The second stressed the importance of an integrated and multiscale approach for the study and conservation of architectural, archaeological and artistic heritage, from SAR to GPR to imaging based diagnostic techniques (Masini and Soldovieri 2011). The third enlarged the field of analysis to civil engineering structures and infrastructures, providing an overview of the effectiveness and the limitations of single diagnostic techniques, which can be overcome through the integration of different methods and technologies and/or the use of robust and novel data processing techniques (Masini et al 2012). As a whole, the special issue put in evidence the factors that affect the choice of diagnostic strategy, such as the material, the spatial characteristics of the objects or sites, the value of the objects to be investigated (cultural or not), the aim of the investigation (knowledge, conservation, restoration) and the issues to be addressed (monitoring, decay assessment). In order to complete the overview of the application fields of sensing technologies this issue has been dedicated to monitoring of cultural heritage and critical infrastructures to address safety and security issues. Particular attention has been paid to the data processing methods of different sensing techniques, from infrared thermography through GPR to SAR. Cascini et al (2013) present the effectiveness of a

    2011-04-22

    The United States has jurisdiction over 3.4 million square miles of ocean expanse greater than the land area of all fifty states combined. This vast marine area offers researchers opportunities to investigate the ocean's role in an integrated Earth system, but also presents challenges to society, including damaging tsunamis and hurricanes, industrial accidents, and outbreaks of waterborne diseases. The 2010 Gulf of Mexico Deepwater Horizon oil spill and 2011 Japanese earthquake and tsunami are vivid reminders that a broad range of infrastructure is needed to advance our still-incomplete understanding of the ocean. The National Research Council (NRC)'s Ocean Studies Board was asked by the National Science and Technology Council's Subcommittee on Ocean Science and Technology, comprised of 25 U.S. government agencies, to examine infrastructure needs for ocean research in the year 2030. This request reflects concern, among a myriad of marine issues, over the present state of aging and obsolete infrastructure, insufficient capacity, growing technological gaps, and declining national leadership in marine technological development; issues brought to the nation's attention in 2004 by the U.S. Commission on Ocean Policy. A 15-member committee of experts identified four themes that encompass 32 future ocean research questions enabling stewardship of the environment, protecting life and property, promoting economic vitality, and increasing fundamental scientific understanding. Many of the questions in the report (e.g., sea level rise, sustainable fisheries, the global water cycle) reflect challenging, multidisciplinary science questions that are clearly relevant today, and are likely to take decades of effort to solve. As such, U.S. ocean research will require a growing suite of ocean infrastructure for a range of activities, such as high quality, sustained time series observations or autonomous monitoring at a broad range of spatial and temporal scales

  18. 'Known Secure Sensor Measurements' for Critical Infrastructure Systems: Detecting Falsification of System State

    Energy Technology Data Exchange (ETDEWEB)

    Miles McQueen; Annarita Giani

    2011-09-01

    This paper describes a first investigation on a low cost and low false alarm, reliable mechanism for detecting manipulation of critical physical processes and falsification of system state. We call this novel mechanism Known Secure Sensor Measurements (KSSM). The method moves beyond analysis of network traffic and host based state information, in fact it uses physical measurements of the process being controlled to detect falsification of state. KSSM is intended to be incorporated into the design of new, resilient, cost effective critical infrastructure control systems. It can also be included in incremental upgrades of already in- stalled systems for enhanced resilience. KSSM is based on known secure physical measurements for assessing the likelihood of an attack and will demonstrate a practical approach to creating, transmitting, and using the known secure measurements for detection.

  20. Approaches for assessment of vulnerability of critical infrastructures to weather-related hazards

    2016-04-01

    Critical infrastructures are essential components for the modern society to maintain its function, and malfunctioning of one of the critical infrastructure systems may have far-reaching consequences. Climate changes may lead to increase in frequency and intensity of weather-related hazards, creating challenges for the infrastructures. This paper outlines approaches to assess vulnerability posed by weather-related hazards to infrastructures. The approaches assess factors that affect the probability of a malfunctioning of the infrastructure should a weather-related threat occur, as well factors that affect the societal consequences of the infrastructure malfunctioning. Even if vulnerability factors are normally very infrastructure specific and hazard dependent, generic factors could be defined and analyzed. For the vulnerability and resilience of the infrastructure, such factors include e.g. robustness, buffer capacity, protection, quality, age, adaptability and transparency. For the vulnerability of the society in relation to the infrastructure, such factors include e.g. redundancy, substitutes and cascading effects. A semi-quantitative, indicator-based approach is proposed, providing schemes for ranking of the most important vulnerability indicators relevant for weather-related hazards on a relative scale. The application of the indicators in a semi-quantitative risk assessment is also demonstrated. In addition, a quantitative vulnerability model is proposed in terms of vulnerability (representing degree of loss) as a function of intensity, which is adaptable to different types of degree of loss (e.g. fraction of infrastructure users that lose their service, fraction of repair costs to full reconstruction costs). The vulnerability model can be calibrated with empirical data using deterministic calibration or a variety of probabilistic calibration approaches to account for the uncertainties within the model. The research leading to these results has received funding

  1. Evaluation of Critical Infrastructure in the Event of Earthquake: A Case Study of Delhi

    2016-04-01

    With changing paradigms of disaster preparedness, the safety and security of critical infrastructure in the event of a geo-hazard has become increasingly important. In a developing and densely populated country like India, which is vulnerable to many different geo-hazards, a lack of clear policy directive regarding safety of such infrastructure could be especially damaging both in terms of life and property. The problem is most acute in India's mega cities, where inefficient infrastructure means that facilities like transportation, communication, and electricity generation are obsolete and vulnerable to sudden disruptions. The present study takes the case of the National Capital Territory of Delhi and attempts to examine the critical infrastructures of the city in the event of an earthquake. Delhi lies in a very active seismic zone with various faults in and around the city. The Government of India has classified Delhi in Zone 4 (High Risk Zone) based on past and expected seismic activities in the Indo-Gangetic Plains. With a population of over 20 Million in the Urban Agglomeration of Delhi, any major earthquake in an already overstretched infrastructure could have a devastating impact. This study will test the critical infrastructures of the city in terms of their disaster preparedness and suggest ways and measures to increase the same.

  2. Toward an ontology framework supporting the integration of geographic information with modeling and simulation for critical infrastructure protection

    Protecting the nation's infrastructure from natural disasters, inadvertent failures, or intentional attacks is a major national security concern. Gauging the fragility of infrastructure assets, and understanding how interdependencies across critical infrastructures affect their behavior, is essential to predicting and mitigating cascading failures, as well as to planning for response and recovery. Modeling and simulation (M&S) is an indispensable part of characterizing this complex system of systems and anticipating its response to disruptions. Bringing together the necessary components to perform such analyses produces a wide-ranging and coarse-grained computational workflow that must be integrated with other analysis workflow elements. There are many points in both types of work flows in which geographic information (GI) services are required. The GIS community recognizes the essential contribution of GI in this problem domain as evidenced by past OGC initiatives. Typically such initiatives focus on the broader aspects of GI analysis workflows, leaving concepts crucial to integrating simulations within analysis workflows to that community. Our experience with large-scale modeling of interdependent critical infrastructures, and our recent participation in a DRS initiative concerning interoperability for this M&S domain, has led to high-level ontological concepts that we have begun to assemble into an architecture that spans both computational and 'world' views of the problem, and further recognizes the special requirements of simulations that go beyond common workflow ontologies. In this paper we present these ideas, and offer a high-level ontological framework that includes key geospatial concepts as special cases of a broader view.

  3. Critical supply network protection against intentional attacks: A game-theoretical model

    International Nuclear Information System (INIS)

    A crucial issue in today's critical supply chains is how to protect facilities against intentional attacks, since it has become unacceptable to ignore the high impact of low probability disruptions caused by these attacks. This article develops a game-theoretical model to deal with the protection of facilities, in the context of the uncapacitated fixed-charge location problem. Given a set of investment alternatives for protecting the facilities against identified threats, the objective is to select the optimal defence strategy. The attacker is considered as a player who tries to maximise the expected damage while weighing against the attacks expenditures. The conflict on facilities vulnerability is modelled using the concept of contest. The vulnerability of a facility is defined by its destruction probability. Contest success functions determine the vulnerability of each facility dependent on the relative investments of the defender and the attacker on each facility, and on the characteristics of the contest. A method is developed to evaluate the utilities of the players (i.e., the defender and the attacker). This method evaluates many expected costs, including the cost needed to restore disabled facilities, the backorder cost, and the cost incurred because of the increase in transportation costs after attacks. In fact, when one or several facilities are unavailable, transportation costs will increase since reassigned customers may receive shipments from facilities which are farther away. The model considers a non-cooperative two-period game between the players, and an algorithm is presented to determine the equilibrium solution and the optimal defence strategy. An illustrative example is presented. The approach is compared to other suggested strategies, and some managerial insights are provided in the context of facility location

  4. Resilience? Insights into the role of Critical Infrastructures Disaster Mitigation Strategies

    Full Text Available Critical infrastructures (CI systems provide essential services “for the maintenance of critical societal functions, including the supply chain, health, safety, security and economic or social well-being of the people” (European Commission, 2008. These systems are exposed to a great number of hazards and threats, which may result in severe consequences for the population, the socio-economic system, and the environment. The issue is particularly relevant at urban level, where the disruption of one CI system can propagate to the other systems and paralyze the entire area. It is therefore necessary, not only to protect CIs through Critical Infrastructure Protection (CIP strategies, but also to enhance the resilience of these areas. This article aims thus at providing some insights related to the evolution of the critical infrastructures disaster mitigation strategies from the sole protection towards resilience: what kind of strategies based on resilience can be developed to address CIs disruption at local or regional level? To what extent do these strategies contribute to increase the resilience level of the entire urban or metropolitan area? The first section focuses on the urban critical infrastructures systems as well as on the way their disruption can impact urban areas. The second section provides with some examples of key measures to operationalize resilience in the field of critical infrastructure disaster mitigation strategies. The last section highlights how the key measures developed to enhance the resilience against CI disruptions can benefit also to broader urban resilience.

  6. Insurance and critical infrastructure protection : is there a connection in an environment of terrorism?

    International Nuclear Information System (INIS)

    This paper investigated the potential role of the insurance industry in enhancing the protection of critical energy infrastructure (CEI). This analysis was conducted in the context of increased concerns about deliberate acts of sabotage related to terrorist activities. A theoretical insurance market analysis was applied to a CEI scenario in order to examine the effects that insurance might have on the vulnerability of the system and subsequent remediation activities. Classical insurance market structures were examined, and problems associated with adverse selection, moral hazards and the role of government were identified. Issues concerning incentive effects induced by insurance were reviewed, as well as issues concerning the interdependence between different operators of the CEI system. An updated literature review was also provided. Results of the study suggested that corporate losses to CEI owners may be far less than the social cost of energy disruption, which in turn provides a reasonable rationale for government as opposed to private intervention. In terms of remediation, the immediate impact of a crippled CEI would overwhelm any private organization, and response would need to be coordinated through public structures. Terrorism insurance, while available, provides relatively large deductibles, as insurance companies are unwilling to accept the risks of moderate damage that may arise. There does not appear to be any evidence that private insurers will be able to provide significant relief from terrorist attacks, and it is unlikely that a private insurance market for terrorism will emerge. An absence of information regarding terrorist activities constrains both insurance purchasers from choosing the best mix of risk management tools, as well as insurance companies seeking to establish the appropriate pricing and conditions for different contracts. It was concluded that governments should support CEI firms in their own efforts to understand the threats; aid in

  7. Interconnectedness and interdependencies of critical infrastructures in the US economy: Implications for resilience

    Chopra, Shauhrat S.; Khanna, Vikas

    2015-10-01

    Natural disasters in 2011 yielded close to 55 billion in economic damages alone in the United States (US), which highlights the need to reduce impacts of such disasters or other deliberate attacks. The US Department of Homeland Security (DHS) identifies a list of 16 Critical Infrastructure Sectors (CIS) whose incapacity due to disruptions would have a debilitating impact on the nation's economy. The goal of this work is to understand the implications of interdependencies among CIS on the resilience of the US economic system as a whole. We develop a framework that combines the empirical economic input-output (EIO) model with graph theory based techniques for understanding interdependencies, interconnectedness and resilience in the US economic system. By representing the US economy as a network, we are able to analyze its topology by separately looking at its unweighted and weighted forms. Topological analysis of the US EIO network suggests that it exhibits small world properties for the unweighted case, and in the weighted case, the throughput of industry sectors follows a power-law with an exponential cutoff. Implications of these topological properties are discussed in the paper. We also simulate hypothetical disruptions on CIS in order to identify industrial sectors that experience the largest economic impacts, and to quantify systemic vulnerability in economic terms. In addition, insights from community detection and hypothetical disruption scenarios help assess vulnerability of individual industrial communities to disruptions on individual CIS. These methodologies also provide insights regarding the extent of coupling between each CIS in the US EIO network. Based on our analysis, we observe that excessive interconnectedness and interdependencies of CIS results in high systemic vulnerability. This information can guide policymakers to design policies that improve resilience of economic networks, and evaluate policies that might indirectly increase coupling

    2013-08-01

    Full Text Available Since a few years, companies that runs business critical applications are increasing their focus on their support infrastructures. Indeed, it is clearly useless to pursue higher systems reliability, when the infrastructure is vulnerable. Aim of this paper is to explore the value of business continuity within the scope of the design of resilient system. The publication of the fifth revision of ANSI/TIA/EIA 942 standard provides operation managers and risk managers with a framework to plan and design resilient infrastructures. It will be shown how to use the aforementioned standard to analyse the gap between the current and the desired resilience level of a system, and suggest the proper steps to reach it, accordingly to the business continuity requirements. This approach was adopted on the case of the power system infrastructure of a primary Italian Application Service Provider, granting 24/7 mission critical services to its customers.

    Most of the work relating to Infrastructure has been concentrated in the new CSC and RPC manufactory at building 904, on the Prevessin site. Brand new gas distribution, powering and HVAC infrastructures are being deployed and the production of the first CSC chambers has started. Other activities at the CMS site concern the installation of a new small crane bridge in the Cooling technical room in USC55, in order to facilitate the intervention of the maintenance team in case of major failures of the chilled water pumping units. The laser barrack in USC55 has been also the object of a study, requested by the ECAL community, for the new laser system that shall be delivered in few months. In addition, ordinary maintenance works have been performed during the short machine stops on all the main infrastructures at Point 5 and in preparation to the Year-End Technical Stop (YETS), when most of the systems will be carefully inspected in order to ensure a smooth running through the crucial year 2012.

  11. Assessing the dynamic material criticality of infrastructure transitions: A case of low carbon electricity

    International Nuclear Information System (INIS)

    Highlights: • We present a method to analyse material criticality of infrastructure transitions. • Criticality is defined as the potential for, and exposure to, supply disruption. • Our method is dynamic reducing the probability of lock-in to at-risk technologies. • We show that supply disruption potential is reducing but exposure is increasing. - Abstract: Decarbonisation of existing infrastructure systems requires a dynamic roll-out of technology at an unprecedented scale. The potential disruption in supply of critical materials could endanger such a transition to low-carbon infrastructure and, by extension, compromise energy security more broadly because low carbon technologies are reliant on these materials in a way that fossil-fuelled energy infrastructure is not. Criticality is currently defined as the combination of the potential for supply disruption and the exposure of a system of interest to that disruption. We build on this definition and develop a dynamic approach to quantifying criticality, which monitors the change in criticality during the transition towards a low-carbon infrastructure goal. This allows us to assess the relative risk of different technology pathways to reach a particular goal and reduce the probability of being ‘locked in’ to currently attractive but potentially future-critical technologies. To demonstrate, we apply our method to criticality of the proposed UK electricity system transition, with a focus on neodymium. We anticipate that the supply disruption potential of neodymium will decrease by almost 30% by 2050; however, our results show the criticality of low carbon electricity production increases ninefold over this period, as a result of increasing exposure to neodymium-reliant technologies

  12. A Game Theoretic Approach to Cyber Attack Prediction

    Energy Technology Data Exchange (ETDEWEB)

    2005-11-28

    The area investigated by this project is cyber attack prediction. With a focus on correlation-based prediction, current attack prediction methodologies overlook the strategic nature of cyber attack-defense scenarios. As a result, current cyber attack prediction methodologies are very limited in predicting strategic behaviors of attackers in enforcing nontrivial cyber attacks such as DDoS attacks, and may result in low accuracy in correlation-based predictions. This project develops a game theoretic framework for cyber attack prediction, where an automatic game-theory-based attack prediction method is proposed. Being able to quantitatively predict the likelihood of (sequences of) attack actions, our attack prediction methodology can predict fine-grained strategic behaviors of attackers and may greatly improve the accuracy of correlation-based prediction. To our best knowledge, this project develops the first comprehensive framework for incentive-based modeling and inference of attack intent, objectives, and strategies; and this project develops the first method that can predict fine-grained strategic behaviors of attackers. The significance of this research and the benefit to the public can be demonstrated to certain extent by (a) the severe threat of cyber attacks to the critical infrastructures of the nation, including many infrastructures overseen by the Department of Energy, (b) the importance of cyber security to critical infrastructure protection, and (c) the importance of cyber attack prediction to achieving cyber security.

    In addition to the intense campaign of replacement of the leaky bushing on the Endcap circuits, other important activities have also been completed, with the aim of enhancing the overall reliability of the cooling infrastructures at CMS. Remaining with the Endcap circuit, the regulating valve that supplies cold water to the primary side of the circuit heat-exchanger, is not well adapted in flow capability and a new part has been ordered, to be installed during a stop of LHC. The instrumentation monitoring of the refilling rate of the circuits has been enhanced and we can now detect leaks as small as 0.5 cc/sec, on circuits that have nominal flow rates of some 20 litres/sec. Another activity starting now that the technical stop is over is the collection of spare parts that are difficult to find on the market. These will be stored at P5 with the aim of reducing down-time in case of component failure. Concerning the ventilation infrastructures, it has been noticed that in winter time the relative humidity leve...

    Structural failures, such as the MacArthur Maze I-880 overpass in Oakland, California and the I-35 bridge in Minneapolis, Minnesota, are recent examples of our national infrastructure's fragility and serve as an important reminder of such infrastructure in our everyday lives. These two failures, as well as the World Trade Center's collapse and the levee failures in New Orleans, highlight the national importance of protecting our infrastructure as much as possible against acts of terrorism and natural hazards. This paper describes a process for evaluating the vulnerability of critical infrastructure to large blast loads using a fully-coupled finite element approach. A description of the finite element software and modeling technique is discussed along with the experimental validation of the numerical tools. We discuss how such an approach can be used for specific problems such as modeling the progressive collapse of a building.

    2008-09-01

    The goal of the work discussed in this document is to understand the risk to the nation of cyber attacks on critical infrastructures. The large body of research results on cyber attacks against physical infrastructure vulnerabilities has not resulted in clear understanding of the cascading effects a cyber-caused disruption can have on critical national infrastructures and the ability of these affected infrastructures to deliver services. This document discusses current research and methodologies aimed at assessing the translation of a cyber-based effect into a physical disruption of infrastructure and thence into quantification of the economic consequences of the resultant disruption and damage. The document discusses the deficiencies of the existing methods in correlating cyber attacks with physical consequences. The document then outlines a research plan to correct those deficiencies. When completed, the research plan will result in a fully supported methodology to quantify the economic consequences of events that begin with cyber effects, cascade into other physical infrastructure impacts, and result in degradation of the critical infrastructure's ability to deliver services and products. This methodology enables quantification of the risks to national critical infrastructure of cyber threats. The work addresses the electric power sector as an example of how the methodology can be applied.

    Societies rely on critical services such as power, water, transport networks and manufacturing. Infrastructure may be sited to minimise exposure to natural hazards but not all can be avoided. The probability of long-range transport of a volcanic plume to a site is comparable to other external hazards that must be considered to satisfy safety assessments. Recent advances in numerical models of plume dispersion and stochastic modelling provide a formalized and transparent approach to probabilistic assessment of hazard distribution. To understand the risks to critical infrastructure far from volcanic sources, it is necessary to quantify their vulnerability to different hazard stressors. However, infrastructure assets (e.g. power plantsand operational facilities) are typically complex systems in themselves, with interdependent components that may differ in susceptibility to hazard impact. Usually, such complexity means that risk either cannot be estimated formally or that unsatisfactory simplifying assumptions are prerequisite to building a tractable risk model. We present a new approach to quantifying risk by bridging expertise of physical hazard modellers and infrastructure engineers. We use a joint expert judgment approach to determine hazard model inputs and constrain associated uncertainties. Model outputs are chosen on the basis of engineering or operational concerns. The procedure facilitates an interface between physical scientists, with expertise in volcanic hazards, and infrastructure engineers, with insight into vulnerability to hazards. The result is a joined-up approach to estimating risk from low-probability hazards to critical infrastructure. We describe our methodology and show preliminary results for vulnerability to volcanic hazards at a typical UK industrial facility. We discuss our findings in the context of developing bespoke assessment of hazards from distant sources in collaboration with key infrastructure stakeholders.

      Most of the CMS infrastructures at P5 will go through a heavy consolidation-work period during LS1. All systems, from the cryogenic plant of the superconducting magnet to the rack powering in the USC55 counting rooms, from the cooling circuits to the gas distribution, will undergo consolidation work. As announced in the last issue of the CMS Bulletin, we present here one of the consolidation projects of LS1: the installation of a new dry-gas plant for inner detectors inertion. So far the oxygen and humidity suppression inside the CMS Tracker and Pixel volumes were assured by flushing dry nitrogen gas evaporated from a large liquid nitrogen tank. For technical reasons, the maximum flow is limited to less than 100 m3/h and the cost of refilling the tank every two weeks with liquid nitrogen is quite substantial. The new dry-gas plant will supply up to 400 m3/h of dry nitrogen (or the same flow of dry air, during shut-downs) with a comparatively minimal operation cost. It has been evaluated that the...

    The various water-cooling circuits ran smoothly over the summer. The overall performance of the cooling system is satisfactory, even if some improvements are possible, concerning the endcap water-cooling and the C6F14 circuits. In particular for the endcap cooling circuit, we aim to lower the water temperature, to provide more margin for RPC detectors. An expert-on-call piquet has been established during the summer global run, assuring the continuous supervision of the installations. An effort has been made to collect and harmonize the existing documentation on the cooling infrastructures at P5. The last six months have seen minor modifications to the electrical power network at P5. Among these, the racks in USC55 for the Tracker and Sniffer systems, which are backed up by the diesel generator in case of power outage, have been equipped with new control boxes to allow a remote restart. Other interventions have concerned the supply of assured power to those installations that are essential for CMS to run eff...

    During the last six months, the main activity on the cooling circuit has essentially been preventive maintenance. At each short machine technical stop, a water sample is extracted out of every cooling circuit to measure the induced radioactivity. Soon after, a visual check of the whole detector cooling network is done, looking for water leaks in sensitive locations. Depending on sub-system availability, the main water filters are replaced; the old ones are inspected and sent to the CERN metallurgical lab in case of suspicious sediments. For the coming winter technical stop, a number of corrective maintenance activities and infrastructure consolidation work-packages are foreseen. A few faulty valves, found on the muon system cooling circuit, will be replaced; the cooling gauges for TOTEM and CASTOR, in the CMS Forward region, will be either changed or shielded against the magnetic stray field. The demineralizer cartridges will be replaced as well. New instrumentation will also be installed in the SCX5 PC farm ...

    During the last winter technical stop, a number of corrective maintenance activities and infrastructure consolidation work-packages were completed. On the surface, the site cooling facility has passed the annual maintenance process that includes the cleaning of the two evaporative cooling towers, the maintenance of the chiller units and the safety checks on the software controls. In parallel, CMS teams, reinforced by PH-DT group personnel, have worked to shield the cooling gauges for TOTEM and CASTOR against the magnetic stray field in the CMS Forward region, to add labels to almost all the valves underground and to clean all the filters in UXC55, USC55 and SCX5. Following the insertion of TOTEM T1 detector, the cooling circuit has been branched off and commissioned. The demineraliser cartridges have been replaced as well, as they were shown to be almost saturated. New instrumentation has been installed in the SCX5 PC farm cooling and ventilation network, in order to monitor the performance of the HVAC system...

    With all the technical services running, the attention has moved toward the next shutdown that will be spent to perform those modifications needed to enhance the reliability of CMS Infrastructures. Just to give an example for the cooling circuit, a set of re-circulating bypasses will be installed into the TS/CV area to limit the pressure surge when a circuit is partially shut-off. This problem has affected especially the Endcap Muon cooling circuit in the past. Also the ventilation of the UXC55 has to be revisited, allowing the automatic switching to full extraction in case of magnet quench. (Normally 90% of the cavern air is re-circulated by the ventilation system.) Minor modifications will concern the gas distribution, while the DSS action-matrix has to be refined according to the experience gained with operating the detector for a while. On the powering side, some LV power lines have been doubled and the final schematics of the UPS coverage for the counting rooms have been released. The most relevant inte...

    The long winter shut-down allows for modifications that will improve the reliability of the detector infrastructures at P5. The annual maintenance of detector services is taking place as well. This means a full stop of water-cooling circuits from November 24th with a gradual restart from mid January 09. The annual maintenance service includes the cleaning of the two SF5 cooling towers, service of the chiller plants on the surface, and the cryogenic plant serving the CMS Magnet. In addition, the overall site power is reduced from 8MW to 2MW, compatible with the switchover to the Swiss power network in winter. Full power will be available again from end of January. Among the modification works planned, the Low Voltage cabinets are being refurbished; doubling the cable sections and replacing the 40A circuit breakers with 60A types. This will reduce the overheating that has been experienced. Moreover, two new LV transformers will be bought and pre-cabled in order to assure a quick swap in case of failure of any...

    Full Text Available Critical dynamics are assumed to be an attractive mode for normal brain functioning as information processing and computational capabilities are found to be optimal in the critical state. Recent experimental observations of neuronal activity patterns following power-law distributions, a hallmark of systems at a critical state, have led to the hypothesis that human brain dynamics could be poised at a phase transition between ordered and disordered activity. A so far unresolved question concerns the medical significance of critical brain activity and how it relates to pathological conditions. Using data from invasive electroencephalogram recordings from humans we show that during epileptic seizure attacks neuronal activity patterns deviate from the normally observed power-law distribution characterizing critical dynamics. The comparison of these observations to results from a computational model exhibiting self-organized criticality (SOC based on adaptive networks allows further insights into the underlying dynamics. Together these results suggest that brain dynamics deviates from criticality during seizures caused by the failure of adaptive SOC.

    Mass gatherings (MG) are characterized by the influx of large numbers of people with the need to have infrastructural changes to support these gatherings. Thus, Public Health Emergency Operations Center (PHEOC) is critical management infrastructure for both the delivery of public health functions and for mounting adequate response during emergencies. The recognition of the importance of PHEOC at the leadership and political level is foundational for the success of any public health intervention during MG. The ability of the PHEOC to effectively function depends on appropriate design and infrastructure, staffing and command structure, and plans and procedures developed prior to the event. Multi-ministerial or jurisdictional coordination will be required and PHEOC should be positioned with such authorities. This paper outlines the essential concepts, elements, design, and operational aspects of PHEOC during MG. PMID:27580322

    Development of real-time predictive modeling to identify the dispersion and/or source(s) of airborne weapons of mass destruction including chemical, biological, radiological, and nuclear material in urban environments is needed to improve response to potential releases of these materials via either terrorist or accidental means. These models will also prove useful in defining airborne pollution dispersion in urban environments for pollution management/abatement programs. Predicting gas flow in an urban setting on a scale of less than a few kilometers is a complicated and challenging task due to the irregular flow paths that occur along streets and alleys and around buildings of different sizes and shapes, i.e., ''urban canyons''. In addition, air exchange between the outside and buildings and subway areas further complicate the situation. Transport models that are used to predict dispersion of WMD/CBRN materials or to back track the source of the release require high-density data and need defensible parameterizations of urban processes. Errors in the data or any of the parameter inputs or assumptions will lead to misidentification of the airborne spread or source release location(s). The need for these models to provide output in a real-time fashion if they are to be useful for emergency response provides another challenge. To improve the ability of New York City's (NYC's) emergency management teams and first response personnel to protect the public during releases of hazardous materials, the New York City Urban Dispersion Program (UDP) has been initiated. This is a four year research program being conducted from 2004 through 2007. This paper will discuss ground level and subway Perfluorocarbon tracer (PFT) release studies conducted in New York City. The studies released multiple tracers to study ground level and vertical transport of contaminants. This paper will discuss the results from these tests and how these results can be used for improving transport models needed for risk assessment.

  15. Multi-Model Framework for Investigating Potential Climate Change Impacts on Interdependent Critical Infrastructure

    Built infrastructure consists of a series of interconnected networks with many coupled interdependencies. Traditionally, risk and vulnerability assessments are conducted one infrastructure at a time, considering only direct impacts on built and planned assets. However, extreme events caused by climate change affect local communities in different respects and stress vital interconnected infrastructures in complex ways that cannot be captured with traditional risk assessment methodologies. We employ a combination of high-performance computing, geographical information science, and imaging methods to examine the impacts of climate change on infrastructure for cities in two different climate regions: Chicago, Illinois in the Midwest and Portland, Maine (and Casco Bay area) in the Northeast. In Illinois, we evaluate effects of changes in regional temperature and precipitation, informed by an extreme climate change projection, population growth and migration, water supply, and technological development, on electricity generation and consumption. In Maine, we determine the aggregate effects of sea level rise, changing precipitation patterns, and population shifts on the depth of the freshwater-saltwater interface in coastal aquifers and the implications of these changes for water supply in general. The purpose of these efforts is to develop a multi-model framework for investigating potential climate change impacts on interdependent critical infrastructure assessing both vulnerabilities and alternative adaptive measures.

Candidate École nationale d'administration publique Julie-Maude Normandin Ph.D. Candidate École nationale d'administration publique Marie-Christine Therrien Professor École nationale d'administration publique The proposed paper presents preliminary results on the resilience of organizations managing critical infrastructure in the Metropolitan Montreal area (Canada). A resilient city is characterized by a network of infrastructures and individuals capable of maintaining their activities in spite of a disturbance (Godschalk, 2002). Critical infrastructures provide essential services for the functioning of society. In a crisis situation, the interruption or a decrease in performance of critical infrastructures could have important impacts on the population. They are also vulnerable to accidents and cascading effects because on their complexity and tight interdependence (Perrow, 1984). For these reasons, protection and security of the essential assets and networks are one of the objectives of organizations and governments. But prevention and recovery are two endpoints of a continuum which include also intermediate concerns: ensuring organizational robustness or failing with elegance rather than catastrophically. This continuum also includes organizational resilience (or system), or the ability to recover quickly after an interruption has occurred. Wildavsky (1988) proposes that anticipation strategies work better against known problems while resilience strategies focus on unknown problems. Anticipation policies can unnecessarily immobilize investments against risks, while resilience strategies include the potential for a certain sacrifice in the interests of a more long-term survival and adaptation to changing threats. In addition, a too large confidence in anticipation strategies can bring loss of capacity of an

    Recent structural failures such as the I-35W Mississippi River Bridge in Minnesota have underscored the urgent need for improved methods and procedures for evaluating our aging transportation infrastructure. This research seeks to develop a basis for a Structural Health Monitoring (SHM) system to provide quantitative information related to the structural integrity of metallic structures to make appropriate management decisions and ensuring public safety. This research employs advanced structural analysis and nondestructive testing (NDT) methods for an accurate fatigue analysis. Metal railroad bridges in New Mexico will be the focus since many of these structures are over 100 years old and classified as fracture-critical. The term fracture-critical indicates that failure of a single component may result in complete collapse of the structure such as the one experienced by the I-35W Bridge. Failure may originate from sources such as loss of section due to corrosion or cracking caused by fatigue loading. Because standard inspection practice is primarily visual, these types of defects can go undetected due to oversight, lack of access to critical areas, or, in riveted members, hidden defects that are beneath fasteners or connection angles. Another issue is that it is difficult to determine the fatigue damage that a structure has experienced and the rate at which damage is accumulating due to uncertain history and load distribution in supporting members. A SHM system has several advantages that can overcome these limitations. SHM allows critical areas of the structure to be monitored more quantitatively under actual loading. The research needed to apply SHM to metallic structures was performed and a case study was carried out to show the potential of SHM-driven fatigue evaluation to assess the condition of critical transportation infrastructure and to guide inspectors to potential problem areas. This project combines the expertise in transportation infrastructure at New

    2013-04-01

    Full Text Available South Africa has made great strides towards protecting critical information infrastructures (CIIs. For example, South Africa recognises the significance of safeguarding places or areas that are essential to the national security of South Africa or the economic and social well-being of South African citizens. For this reason South Africa has established mechanisms to assist in preserving the integrity and security of CIIs. The measures provide inter alia for the identification of CIIs; the registration of the full names, address and contact details of the CII administrators (the persons who manage CIIs; the identification of the location(s of CIIs or their component parts; and the outlining of the general descriptions of information or data stored in CIIs.It is argued that the measures to protect CIIs in South Africa are inadequate. In particular, the measures rely on a one-size-fits-all approach to identify and classify CIIs. For this reason the South African measures are likely to lead to the adoption of a paradigm that considers every infrastructure, data or database, regardless of its significance or importance, to be key or critical.

    Virtualization technology plays a key role in cloud computing. Thus, the security issues of virtualization tools (hypervisors, emulators, etc.) should be under precise consideration. However, threats of insider attacks are underestimated. The virtualization tools and hypervisors have been poorly protected from this type of attacks. Furthermore, hypervisor is one of the most critical elements in cloud computing infrastructure. Firstly, hypervisor vulnerabilities analysis is provided. Secondly, a formal model of insider attack on hypervisor is developed. Consequently, on the basis of the formal attack model, we propose a new methodology of hypervisor stability evaluation. In this paper, certain security countermeasures are considered that should be integrated in hypervisor software architecture.

    The research project "Integrated System for Transport Infrastructure surveillance and Monitoring by Electromagnetic Sensing" (ISTIMES), was approved in the 7th Framework Programme, in the Joint Call ICT and Security and started on 1st July 2009. The purpose of ISTIMES project is to design, assess and promote an ICT-based system, exploiting distributed and local sensors, for non-destructive electromagnetic monitoring in order to achieve the critical transport infrastructures more reliable and safe. The transportation sector's components are susceptible to the consequences of natural disasters and can also be attractive as terrorist targets. The sector's size, its physically dispersed and decentralized nature, the many public and private entities involved in its operations, the critical importance of cost considerations, and the inherent requirement of convenient accessibility to its services by all users - make the transportation particularly vulnerable to security and safety threats. As well known, the surface transportation system consists of interconnected infrastructures including highways, transit systems, railroads, airports, waterways, pipelines and ports, and the vehicles, aircraft, and vessels that operate along these networks. Thus, interdependencies exist between transportation and nearly every other sector of the economy and the effective operation of this system is essential to the European economic productivity; therefore, transportation sector protection is of paramount importance since threats to it may impact other industries that rely on it. The system exploits an open network architecture that can accommodate a wide range of sensors, static and mobile, and can be easily scaled up to allow the integration of additional sensors and interfacing with other networks. It relies on heterogeneous state-of-the-art electromagnetic sensors, enabling a self-organizing, self-healing, ad-hoc networking of terrestrial sensors, supported by specific satellite

And then, three relative algorithms to construct pairing-friendly elliptic curve are put forward. 10 elliptic curves with low hamming weight 4 under 160 bits are presented to demonstrate the utility of our approach. Finally, the evaluation also indicates that it is more efficient to compute Tate pairing with our curves, than that of Bertoni et al. PMID:27564373

    2016-04-01

    This work presents the results of more than ten years of observations, performed on a regular basis, on a municipal solid waste disposal located in Italy. Observational data are generated by the combination of non-invasive techniques, involving the direct measurement of biogas release to the atmosphere and thermal infrared imaging. In fact, part of the generated biogas tends to escape from the landfill surface even when collecting systems are installed and properly working. Thus, methodologies for estimating the behaviour of a landfill system by means of direct and/or indirect measurement systems have been developed in the last decades. It is nowadays known that these infrastructures produce more than 20% of the total anthropogenic methane released to the atmosphere, justifying the need for a systematic and efficient monitoring of such infrastructures. During the last 12 years, observational data regarding a solid waste disposal site located in Tuscany (Italy) have been collected on a regular basis. The collected datasets consist in direct measurements of gas flux with the accumulation chamber method, combined with the detection of thermal anomalies by infrared radiometry. This work discusses the evolution of the estimated performance of the landfill system, its trends, the benefits and the critical aspects of such relatively long-term monitoring activity.

  8. Will climate change increase the risk for critical infrastructure failures in Europe due to extreme precipitation?

    Nissen, Katrin; Ulbrich, Uwe

    2016-04-01

    An event based detection algorithm for extreme precipitation is applied to a multi-model ensemble of regional climate model simulations. The algorithm determines extent, location, duration and severity of extreme precipitation events. We assume that precipitation in excess of the local present-day 10-year return value will potentially exceed the capacity of the drainage systems that protect critical infrastructure elements. This assumption is based on legislation for the design of drainage systems which is in place in many European countries. Thus, events exceeding the local 10-year return value are detected. In this study we distinguish between sub-daily events (3 hourly) with high precipitation intensities and long-duration events (1-3 days) with high precipitation amounts. The climate change simulations investigated here were conducted within the EURO-CORDEX framework and exhibit a horizontal resolution of approximately 12.5 km. The period between 1971-2100 forced with observed and scenario (RCP 8.5 and RCP 4.5) greenhouse gas concentrations was analysed. Examined are changes in event frequency, event duration and size. The simulations show an increase in the number of extreme precipitation events for the future climate period over most of the area, which is strongest in Northern Europe. Strength and statistical significance of the signal increase with increasing greenhouse gas concentrations. This work has been conducted within the EU project RAIN (Risk Analysis of Infrastructure Networks in response to extreme weather).

    This document presents the security automated Risk Assessment Methodology (RAM) prototype tool developed by Sandia National Laboratories (SNL). This work leverages SNL's capabilities and skills in security risk analysis and the development of vulnerability assessment/risk assessment methodologies to develop an automated prototype security RAM tool for critical infrastructures (RAM-CITM). The prototype automated RAM tool provides a user-friendly, systematic, and comprehensive risk-based tool to assist CI sector and security professionals in assessing and managing security risk from malevolent threats. The current tool is structured on the basic RAM framework developed by SNL. It is envisioned that this prototype tool will be adapted to meet the requirements of different CI sectors and thereby provide additional capabilities.

    2015-01-01

    We suggest an approach for maintaining and enhancing resilience that integrates the resilience capabilities of Critical Infrastructures (CIs) into the emergency management cycle (prevention, preparedness, response, and recovery). This allows emergency services to explicitly address resilience...... improvement measures while planning to cope with CI disruptions. To operationalise this approach we have developed a hierarchical taxonomy that classifies system resilience capabilities into intra- and interorganisational categories. Capabilities are defined as a combination of assets, resources and processes...... resilience capability building cycle completes the framework, enabling a systematic implementation of relevant capabilities and making gap analysis with regard to resilience deficits. The planning of training exercises to enhance CI resilience can also benefit from the approach....

    Full Text Available The monitoring and control of urban critical infrastructures consists of the protection of assets such as houses, offices, government and private buildings, with low cost, high quality and high dependability. In order to satisfy all these requirements at the same time, the control of a number of assets has to be performed by means of automated systems based on networks of heterogeneous sensors. This new concept idea is based on the use of unmanned operations at each of the many remote assets (each asset is monitored through a network of sensors and a man-in-the-loop automated control in a central site (Operational Center, which performs alarm detection and system management.

  13. Cyber-Physical Systems for Critical Infrastructure Protection: A Wireless Sensor Network Application for Electric Grid Monitoring

    Science.gov (United States)

    Saint, Martin

    Critical infrastructure includes resources which are essential to the function of society. Despite an increased focus on protecting U.S. critical infrastructure, some sectors including the electric grid are more vulnerable than ever. Existing critical infrastructure protection (CIP) regulations and the monitoring and control systems used to achieve them have not met performance expectations. This indicates that the next generation of grid control should explore new architectures. This thesis explores the question of whether a cyber-physical system in the form of wireless sensor networks can be used to improve CIP. We examine efforts by others to design a wireless sensor module for monitoring transmission and distribution lines, and note that this work includes little information about the performance of the communications subsystem. Laboratory testing of throughput and reliability for one example communication network are undertaken here, along with consideration of the short message service as one alternative for backhauling sensor data.

    There are many separated infrastructural objects within a harbor area that may be considered "critical", such as gas and oil terminals or anchored naval vessels. Those objects require special protection, including security systems capable of monitoring both surface and underwater areas, because an intrusion into the protected area may be attempted using small surface vehicles (boats, kayaks, rafts, floating devices with weapons and explosives) as well as underwater ones (manned or unmanned submarines, scuba divers). The paper will present the concept of multisensor security system for a harbor protection, capable of complex monitoring of selected critical objects within the protected area. The proposed system consists of a command centre and several different sensors deployed in key areas, providing effective protection from land and sea, with special attention focused on the monitoring of underwater zone. The initial project of such systems will be presented, its configuration and initial tests of the selected components. The protection of surface area is based on medium-range radar and LLTV and infrared cameras. Underwater zone will be monitored by a sonar and acoustic and magnetic barriers, connected into an integrated monitoring system. Theoretical analyses concerning the detection of fast, small surface objects (such as RIB boats) by a camera system and real test results in various weather conditions will also be presented.

  18. Building safeguards infrastructure

    International Nuclear Information System (INIS)

    Much has been written in recent years about the nuclear renaissance - the rebirth of nuclear power as a clean and safe source of electricity around the world. Those who question the nuclear renaissance often cite the risk of proliferation, accidents or an attack on a facility as concerns, all of which merit serious consideration. The integration of three areas - sometimes referred to as 3S, for safety, security and safeguards - is essential to supporting the clean and safe growth of nuclear power, and the infrastructure that supports these three areas should be robust. The focus of this paper will be on the development of the infrastructure necessary to support safeguards, and the integration of safeguards infrastructure with other elements critical to ensuring nuclear energy security

    In 2006, the Engineer Research and Development Center (ERDC) began a program designed to meet the capability gap associated with remote assessment of critical infrastructure. This program addresses issues arising from the use of geophysical techniques to solve engineering problems through persistent monitoring of critical infrastructure using infrasound. In the original 2006-2009 study of a railroad bridge in Ft. Leonard Wood, MO, the fundamental modes of motion of the structure were detected at up to 30 km away, with atmospheric excitation deemed to be the source driver. Follow-on research focused on the mechanically driven modes excited by traffic, with directional acoustic emanations. The success of the Ft. Wood ambient excitation study resulted in several subsequent programs to push the boundaries of this new technique for standoff assessment, discussed herein. Detection of scour and river system health monitoring are serious problems for monitoring civil infrastructure, from both civilian and military perspectives. Knowledge of overall system behavior over time is crucial for assessment of bridge foundations and barge navigation. This research focuses on the same steel-truss bridge from the Ft. Wood study, and analyzes 3D and 2D substructure models coupled with the superstructure reaction loads to assess the modal deformations within the infrasound bandwidth and the correlation to scour of embedment material. The Urban infrasound program is infrasound modeling, data analysis, and sensor research leading to the detection, classification and localization of threat activities in complex propagation environments. Three seismo-acoustic arrays were deployed on rooftops across the Southern Methodist University campus in Dallas, Texas, to characterize the urban infrasound environment. Structural sources within 15 km of the arrays have been identified through signal processing and confirmed through acoustical models. Infrasound is also being studied as a means of

    Natural hazard events can induce severe impacts on the built environment; they can hit wide and densely populated areas, where there is a large number of (inter)dependent technological systems whose damages could cause the failure or malfunctioning of further different services, spreading the impacts on wider geographical areas. The EU project CIPRNet (Critical Infrastructures Preparedness and Resilience Research Network) is realizing an unprecedented Decision Support System (DSS) which enables to operationally perform risk prediction on Critical Infrastructures (CI) by predicting the occurrence of natural events (from long term weather to short nowcast predictions, correlating intrinsic vulnerabilities of CI elements with the different events' manifestation strengths, and analysing the resulting Damage Scenario. The Damage Scenario is then transformed into an Impact Scenario, where punctual CI element damages are transformed into micro (local area) or meso (regional) scale Services Outages. At the smaller scale, the DSS simulates detailed city models (where CI dependencies are explicitly accounted for) that are of important input for crisis management organizations whereas, at the regional scale by using approximate System-of-Systems model describing systemic interactions, the focus is on raising awareness. The DSS has allowed to develop a novel simulation framework for predicting earthquakes shake maps originating from a given seismic event, considering the shock wave propagation in inhomogeneous media and the subsequent produced damages by estimating building vulnerabilities on the basis of a phenomenological model [1, 2]. Moreover, in presence of areas containing river basins, when abundant precipitations are expected, the DSS solves the hydrodynamic 1D/2D models of the river basins for predicting the flux runoff and the corresponding flood dynamics. This calculation allows the estimation of the Damage Scenario and triggers the evaluation of the Impact Scenario

    Full Text Available Critical infrastructure is defined as a network including telecommunications, informationservices, energy transport (electrical lines, natural gas and oil pipes, water supply, goods and personstransportation, financial, banking and emergency response services. All these are so significant that adisequilibrium or interruption of their operation would have a disturbing effect upon the daily life.Estimating the damage done by natural hazards to certain critical infrastructure sectors is considered animportant interest topic. The main purpose of this research is the estimation of the damages generatedby floods and flash-floods on the critical infrastructure in Maramureş County during 2005-2010. Thedamages analysis is based mainly on observations and quantitative data, obtained after a thoroughanalysis of literature and reports from the Ministry of Environment and Forests and the Inspectorate forEmergency Situation of Maramureş County. The results of the study were alarming. The damages causedby floods during the period subjected to study reach approximately 32 million dollars, highlighting theneed for an integrated management system for critical infrastructure protection.

    Following recommendations made in Homeland Security Presidential Directive 7, which established a national policy for the identification and increased protection of critical infrastructure and key resources (CIKR) by Federal departments and agencies, the U.S. Department of Homeland Security (DHS) in 2006 developed the Enhanced Critical Infrastructure Protection (ECIP) program. The ECIP program aimed to provide a closer partnership with state, regional, territorial, local, and tribal authorities in fulfilling the national objective to improve CIKR protection. The program was specifically designed to identify protective measures currently in place in CIKR and to inform facility owners/operators of the benefits of new protective measures. The ECIP program also sought to enhance existing relationships between DHS and owners/operators of CIKR and to build relationships where none existed (DHS 2008; DHS 2009). In 2009, DHS and its protective security advisors (PSAs) began assessing CIKR assets using the ECIP program and ultimately produced individual protective measure and vulnerability values through the protective measure and vulnerability indices (PMI/VI). The PMI/VI assess the protective measures posture of individual facilities at their 'weakest link,' allowing for a detailed analysis of the most vulnerable aspects of the facilities (Schneier 2003), while maintaining the ability to produce an overall protective measures picture. The PMI has six main components (physical security, security management, security force, information sharing, protective measures assessments, and dependencies) and focuses on actions taken by a facility to prevent or deter the occurrence of an incident (Argonne National Laboratory 2009). As CIKR continue to be assessed using the PMI/VI and owners/operators better understand how they can prevent or deter incidents, academic research, practitioner emphasis, and public policy formation have increasingly focused on resilience as a

    The US Department of Homeland Security (DHS) has directed its Protective Security Advisors (PSAs) to form partnerships with the owners and operators of assets most essential to the Nation's well being - a subclass of critical infrastructure and key resources (CIKR) - and to conduct site visits for these and other high-risk assets as part of the Enhanced Critical Infrastructure Protection (ECIP) Program. During each such visit, the PSA documents information about the facility's current CIKR protection posture and overall security awareness. The primary goals for ECIP site visits (DHS 2009) are to: (1) inform facility owners and operators of the importance of their facilities as an identified high-priority CIKR and the need to be vigilant in light of the ever-present threat of terrorism; (2) identify protective measures currently in place at these facilities, provide comparisons of CIKR protection postures across like assets, and track the implementation of new protective measures; and (3) enhance existing relationships among facility owners and operators; DHS; and various Federal, State, local tribal, and territorial partners. PSAs conduct ECIP visits to assess overall site security; educate facility owners and operators about security; help owners and operators identify gaps and potential improvements; and promote communication and information sharing among facility owners and operators, DHS, State governments, and other security partners. Information collected during ECIP visits is used to develop metrics; conduct sector-by-sector and cross-sector vulnerability comparisons; identify security gaps and trends across CIKR sectors and subsectors; establish sector baseline security survey results; and track progress toward improving CIKR security through activities, programs, outreach, and training (Snyder 2009). The data being collected are used in a framework consistent with the National Infrastructure Protection Plan (NIPP) risk criteria (DHS 2009). The

  4. Natural disaster risk analysis for critical infrastructure systems: An approach based on statistical learning theory

    International Nuclear Information System (INIS)

    Probabilistic risk analysis has historically been developed for situations in which measured data about the overall reliability of a system are limited and expert knowledge is the best source of information available. There continue to be a number of important problem areas characterized by a lack of hard data. However, in other important problem areas the emergence of information technology has transformed the situation from one characterized by little data to one characterized by data overabundance. Natural disaster risk assessments for events impacting large-scale, critical infrastructure systems such as electric power distribution systems, transportation systems, water supply systems, and natural gas supply systems are important examples of problems characterized by data overabundance. There are often substantial amounts of information collected and archived about the behavior of these systems over time. Yet it can be difficult to effectively utilize these large data sets for risk assessment. Using this information for estimating the probability or consequences of system failure requires a different approach and analysis paradigm than risk analysis for data-poor systems does. Statistical learning theory, a diverse set of methods designed to draw inferences from large, complex data sets, can provide a basis for risk analysis for data-rich systems. This paper provides an overview of statistical learning theory methods and discusses their potential for greater use in risk analysis

    2011-08-01

    Resiliency and cyber security of modern critical infrastructures is becoming increasingly important with the growing number of threats in the cyber-environment. This paper proposes an extension to a previously developed fuzzy logic based anomaly detection network security cyber sensor via incorporating Type-2 Fuzzy Logic (T2 FL). In general, fuzzy logic provides a framework for system modeling in linguistic form capable of coping with imprecise and vague meanings of words. T2 FL is an extension of Type-1 FL which proved to be successful in modeling and minimizing the effects of various kinds of dynamic uncertainties. In this paper, T2 FL provides a basis for robust anomaly detection and cyber security state awareness. In addition, the proposed algorithm was specifically developed to comply with the constrained computational requirements of low-cost embedded network security cyber sensors. The performance of the system was evaluated on a set of network data recorded from an experimental cyber-security test-bed.

  6. Attenuation of Storm Surge Flooding By Wetlands in the Chesapeake Bay: An Integrated Geospatial Framework Evaluating Impacts to Critical Infrastructure

    2014-12-01

    Areas along the Chesapeake Bay and its tributaries are extremely vulnerable to hurricane flooding, as evidenced by the costly effects and severe impacts of recent storms along the Virginia coast, such as Hurricane Isabel in 2003 and Hurricane Sandy in 2012. Coastal wetlands, in addition to their ecological importance, are expected to mitigate the impact of storm surge by acting as a natural protection against hurricane flooding. Quantifying such interactions helps to provide a sound scientific basis to support planning and decision making. Using storm surge flooding from various historical hurricanes, simulated using a coupled hydrodynamic wave model (ADCIRC-SWAN), we propose an integrated framework yielding a geospatial identification of the capacity of Chesapeake Bay wetlands to protect critical infrastructure. Spatial identification of Chesapeake Bay wetlands is derived from the National Wetlands Inventory (NWI), National Land Cover Database (NLCD), and the Coastal Change Analysis Program (C-CAP). Inventories of population and critical infrastructure are extracted from US Census block data and FEMA's HAZUS-Multi Hazard geodatabase. Geospatial and statistical analyses are carried out to develop a relationship between wetland land cover, hurricane flooding, population and infrastructure vulnerability. These analyses result in the identification and quantification of populations and infrastructure in flooded areas that lie within a reasonable buffer surrounding the identified wetlands. Our analysis thus produces a spatial perspective on the potential for wetlands to attenuate hurricane flood impacts in critical areas. Statistical analysis will support hypothesis testing to evaluate the benefits of wetlands from a flooding and storm-surge attenuation perspective. Results from geospatial analysis are used to identify where interactions with critical infrastructure are relevant in the Chesapeake Bay.

  7. Quantitative physical models of volcanic phenomena for hazards assessment of critical infrastructures

    Science.gov (United States)

    Costa, Antonio

    2016-04-01

    Volcanic hazards may have destructive effects on economy, transport, and natural environments at both local and regional scale. Hazardous phenomena include pyroclastic density currents, tephra fall, gas emissions, lava flows, debris flows and avalanches, and lahars. Volcanic hazards assessment is based on available information to characterize potential volcanic sources in the region of interest and to determine whether specific volcanic phenomena might reach a given site. Volcanic hazards assessment is focussed on estimating the distances that volcanic phenomena could travel from potential sources and their intensity at the considered site. Epistemic and aleatory uncertainties strongly affect the resulting hazards assessment. Within the context of critical infrastructures, volcanic eruptions are rare natural events that can create severe hazards. In addition to being rare events, evidence of many past volcanic eruptions is poorly preserved in the geologic record. The models used for describing the impact of volcanic phenomena generally represent a range of model complexities, from simplified physics based conceptual models to highly coupled thermo fluid dynamical approaches. Modelling approaches represent a hierarchy of complexity, which reflects increasing requirements for well characterized data in order to produce a broader range of output information. In selecting models for the hazard analysis related to a specific phenomenon, questions that need to be answered by the models must be carefully considered. Independently of the model, the final hazards assessment strongly depends on input derived from detailed volcanological investigations, such as mapping and stratigraphic correlations. For each phenomenon, an overview of currently available approaches for the evaluation of future hazards will be presented with the aim to provide a foundation for future work in developing an international consensus on volcanic hazards assessment methods.

    CERN Document Server

    Laprie, Jean-Claude; Kaaniche, Mohamed

    2008-01-01

    The aim of this paper is to provide qualitative models characterizing interdependencies related failures of two critical infrastructures: the electricity infrastructure and the associated information infrastructure. The interdependen-cies of these two infrastructures are increasing due to a growing connection of the power grid networks to the global information infrastructure, as a conse-quence of market deregulation and opening. These interdependencies increase the risk of failures. We focus on cascading, escalating and common-cause fail-ures, which correspond to the main causes of failures due to interdependencies. We address failures in the electricity infrastructure, in combination with acci-dental failures in the information infrastructure, then we show briefly how ma-licious attacks in the information infrastructure can be addressed.

    The telecommunications sector plays a pivotal role in the system of increasingly connected and interdependent networks that make up national infrastructure. An assessment of the probable structure and function of the bit-moving industry in the twenty-first century must include issues associated with the surety of telecommunications. The term surety, as used here, means confidence in the acceptable behavior of a system in both intended and unintended circumstances. This paper outlines various engineering approaches to surety in systems, generally, and in the telecommunications infrastructure, specifically. It uses the experience and expectations of the telecommunications system of the US as an example of the global challenges. The paper examines the principal factors underlying the change to more distributed systems in this sector, assesses surety issues associated with these changes, and suggests several possible strategies for mitigation. It also studies the ramifications of what could happen if this sector became a target for those seeking to compromise a nation`s security and economic well being. Experts in this area generally agree that the U. S. telecommunications sector will eventually respond in a way that meets market demands for surety. Questions remain open, however, about confidence in the telecommunications sector and the nation`s infrastructure during unintended circumstances--such as those posed by information warfare or by cascading software failures. Resolution of these questions is complicated by the lack of clear accountability of the private and the public sectors for the surety of telecommunications.

    2011-06-01

    The United States has jurisdiction over 3.4 million square miles of ocean—an expanse greater than the land area of all 50 states combined. This vast marine area offers researchers opportunities to investigate the ocean's role in an integrated Earth system but also presents challenges to society, including damaging tsunamis and hurricanes, industrial accidents, and outbreaks of waterborne diseases. The 2010 Gulf of Mexico Deepwater Horizon oil spill and 2011 Japanese earthquake and tsunami are vivid reminders that a broad range of infrastructure is needed to advance scientists' still incomplete understanding of the ocean. The National Research Council's (NRC) Ocean Studies Board was asked by the National Science and Technology Council's Subcommittee on Ocean Science and Technology, comprising 25 U.S. government agencies, to examine infrastructure needs for ocean research in the year 2030. This request reflects concern, among a myriad of marine issues, over the present state of aging and obsolete infrastructure, insufficient capacity, growing technological gaps, and declining national leadership in marine technological development; these issues were brought to the nation's attention in 2004 by the U.S. Commission on Ocean Policy.

  15. Policies to Avoid Cost Overruns in Infrastructure Projects: Critical Evaluation and Recommendations

    Directory of Open Access Journals (Sweden)

    2014-09-01

    Full Text Available Many infrastructure projects have cost overruns and there has been a lot of research both on why these cost overruns occur and what can be done to reduce hem. Bent Flyvbjerg is the leading researcher in the area and in this article his proposals are used as the starting point. Besides a literature review, a questionnaire was sent out to experienced Swedish project managers to find out what they thought could reduce cost overruns. The literature review and the questionnaire were the foundation for the proposals formulated in this article. Proposals concerned three areas: (1. Organisational macro-structure, e.g. using more PPP projects but also decentralisation of budgets where cost overruns in one project in a region lead to less alternative projects in the specific region. (2. Organisational quality: It should be easy to see when and where cost overruns occur and who was responsible. There should be a well-developed knowledge management system in the organisation and an organisation culture of openness with a focus on improvements. (3. Organisational processes, e.g. a systematic use of external reviewers in different stages of a project.   Keywords: Cost overruns, Infrastructure projects, Policy measures

    2005-01-01

    Integrated System Health Management (ISHM) architectures for spacecraft will include hard real-time, critical subsystems and soft real-time monitoring subsystems. Interaction between these subsystems will be necessary and an architecture supporting multiple criticality levels will be required. Demonstration hardware for the Integrated Safety-Critical Advanced Avionics Communication & Control (ISAACC) system has been developed at NASA Marshall Space Flight Center. It is a modular system using a commercially available time-triggered protocol, ?Tp/C, that supports hard real-time distributed control systems independent of the data transmission medium. The protocol is implemented in hardware and provides guaranteed low-latency messaging with inherent fault-tolerance and fault-containment. Interoperability between modules and systems of modules using the TTP/C is guaranteed through definition of messages and the precise message schedule implemented by the master-less Time Division Multiple Access (TDMA) communications protocol. "Plug-and-play" capability for sensors and actuators provides automatically configurable modules supporting sensor recalibration and control algorithm re-tuning without software modification. Modular components of controlled physical system(s) critical to control algorithm tuning, such as pumps or valve components in an engine, can be replaced or upgraded as "plug and play" components without modification to the ISAACC module hardware or software. ISAACC modules can communicate with other vehicle subsystems through time-triggered protocols or other communications protocols implemented over Ethernet, MIL-STD- 1553 and RS-485/422. Other communication bus physical layers and protocols can be included as required. In this way, the ISAACC modules can be part of a system-of-systems in a vehicle with multi-tier subsystems of varying criticality. The goal of the ISAACC architecture development is control and monitoring of safety critical systems of a

    There are many separated infrastructural objects within a harbor area that may be considered "critical", such as gas and oil terminals or anchored naval vessels. Those objects require special protection, including security systems capable of monitoring both surface and underwater areas, because an intrusion into the protected area may be attempted using small surface vehicles (boats, kayaks, rafts, floating devices with weapons and explosives) as well as underwater ones (manned or unmanned submarines, scuba divers). The cameras used in security systems operate in several different spectral ranges in order to improve the probability of detection of incoming objects (potential threats). The cameras should then have adequate range parameters for detection, recognition and identification and those parameters, both measured and obtained through numerical simulations, will be presented in the paper. The range parameters of thermal cameras were calculated using NVTherm software package. Parameters of four observation thermal cameras were also measured on a specialized test stand at Institute of Optoelectronics, MUT. This test stand makes it also possible to test visual cameras. The parameters of five observation cameras working in the visual range were measured and on the basis of those data the detection, recognition and identification ranges were determined. The measurement results and simulation data will be compared. The evaluation of range parameters obtained for the tested camera types will define their usability in the real security system for the protection of selected critical infrastructure of a seaport.small surface objects (such as RIB boats) by a camera system and real test results in various weather conditions will also be presented.

    Extreme storm rainfall data in the Southeastern United States are being collected and analyzed to assess their potential impacts on design precipitation amounts. Probable Maximum Precipitation (PMP) from National Weather Service Hydromet Report 51 is currently used for design rainfall estimates in the eastern U.S. The design precipitation estimates are based on an Army Corps of Engineers storm depth-area duration (D-A-D) catalog that is nearly 40 years old. We develop an electronic D-A-D database of SE U.S. storms for the period 1889-1972 from existing sources, describe the spatial and temporal limitations of those data, and how design estimates based on these data have changed over time. An electronic database of individual extreme storms that have occurred since 1972 near the Carolinas is under development. NWS WSR-88D archive radar data, NOAA Multisensor Precipitation Reanalysis data, NCDC COOP station precipitation data, and NOAA HURDAT information are used in storm analysis. We focus on warm-season tropical cyclones, as these systems are the critical storm rainfall-producing mechanisms in the SE U.S. that result in extreme floods. We examine orographic enhancement of rainfall in the Appalachians, in addition to Piedmont and coastal areas. Exceedance probabilities and uncertainties of design precipitation amounts are being estimated, so that risk-based hazard assessments can potentially be explored. Potential effects of climate variability on the extreme storm estimates, at time-scales of interest in design precipitation applications, are also under investigation.

    The majority of restoration strategies in the wake of large-scale disasters have focused on short-term emergency response solutions. Few consider medium- to long-term restoration strategies to reconnect urban areas to national supply chain interdependent critical infrastructure systems (SCICI). These SCICI promote the effective flow of goods, services, and information vital to the economic vitality of an urban environment. To re-establish the connectivity that has been broken during a disaster between the different SCICI, relationships between these systems must be identified, formulated, and added to a common framework to form a system-level restoration plan. To accomplish this goal, a considerable collection of SCICI data is necessary. The aim of this paper is to review what data are required for model construction, the accessibility of these data, and their integration with each other. While a review of publically available data reveals a dearth of real-time data to assist modeling long-term recovery following an extreme event, a significant amount of static data does exist and these data can be used to model the complex interdependencies needed. For the sake of illustration, a particular SCICI (transportation) is used to highlight the challenges of determining the interdependencies and creating models capable of describing the complexity of an urban environment with the data publically available. Integration of such data as is derived from public domain sources is readily achieved in a geospatial environment, after all geospatial infrastructure data are the most abundant data source and while significant quantities of data can be acquired through public sources, a significant effort is still required to gather, develop, and integrate these data from multiple sources to build a complete model. Therefore, while continued availability of high quality, public information is essential for modeling efforts in academic as well as government communities, a more

    Nuclear facility personnel expend considerable efforts to ensure that their facilities can maintain continuity of operations against both natural and man-made threats. Historically, most attention has been placed on physical security. Recently however, the threat of cyber-related attacks has become a recognized and growing world-wide concern. Much attention has focused on the vulnerability of the electric grid and chemical industries to cyber attacks, in part, because of their use of Supervisory Control and Data Acquisition (SCADA) systems. Lessons learned from work in these sectors indicate that the cyber threat may extend to other critical infrastructures including sites where nuclear and radiological materials are now stored. In this context, this white paper presents a hypothetical scenario by which a determined adversary launches a cyber attack that compromises the physical protection system and results in a reduced security posture at such a site. The compromised security posture might then be malevolently exploited in a variety of ways. The authors conclude that the cyber threat should be carefully considered for all nuclear infrastructures.

    Full Text Available Disaster risk information is spatial in nature and Geographic Information Systems (GIS and Remote Sensing (RS play an important key role by the services they provide to society. In this context, to risk management and governance, in general, and to civil protection, specifically (termed differently in many countries, and includes, for instance: civil contingencies in the UK, homeland security in the USA, disaster risk reduction at the UN level. The main impetus of this article is to summarize key contributions and challenges in utilizing and accepting GIS and RS methods and data for disaster risk governance, which includes public bodies, but also risk managers in industry and practitioners in search and rescue organizations. The article analyzes certain method developments, such as vulnerability indicators, crowdsourcing, and emerging concepts, such as Volunteered Geographic Information, but also investigates the potential of the topic Critical Infrastructure as it could be applied on spatial assets and GIS and RS itself. Intended to stimulate research on new and emerging fields, this article’s main contribution is to move spatial research toward a more reflective stance where opportunities and challenges are equally and transparently addressed in order to gain more scientific quality. As a conclusion, GIS and RS can play a pivotal role not just in delivering data but also in connecting and analyzing data in a more integrative, holistic way.

    2013-01-01

    In the Wordwide LHC Computing Grid (WLCG) project the Tier centres are of paramount importance for storing and accessing experiment data and for running the batch jobs necessary for experiment production activities. Although Tier2 sites provide a significant fraction of the resources a non-availability of resources at the Tier0 or the Tier1s can seriously harm not only WLCG Operations but also the experiments' workflow and the storage of LHC data which are very expensive to reproduce. This is why availability requirements for these sites are high and committed in the WLCG Memorandum of Understanding (MoU). In this talk we describe the workflow of GGUS ALARMs, the only 24/7 mechanism available to LHC experiment experts for reporting to the Tier0 or the Tier1s problems with their Critical Services. Conclusions and experience gained from the detailed drills performed in each such ALARM for the last 4 years are explained and the shift with time of Type of Problems met. The physical infrastructure put in place to ...

    High-energy muons generated from cosmic-ray particle showers have been shown to exhibit properties ideal for imaging the interior of large structures. This paper explores the possibility of using a single portable muon detector in conjunction with image reconstruction methods used in nuclear medicine to reconstruct a 3D image of the interior of critical infrastructure such as the Zero Energy Deuterium (ZED-2) research reactor at Canadian Nuclear Laboratories' Chalk River site. The ZED-2 reactor core and muon detector arrangement are modeled in GEANT4 and Monte Carlo measurements of the resultant muon throughput and angular distribution at several angles of rotation around the reactor are generated. Statistical analysis is then performed on these measurements based on the well-defined flux and angular distribution of muons expected near the surface of the earth. The results of this analysis are shown to produce reconstructed images of the spatial distribution of nuclear fuel within the core for multiple fuel c...

    a flux-splitting technique with a reviewed Roe-Riemann solver and appropriate source-term formulations to ensure full conservativeness. Additionally, STAV-2D features Lagrangian-Eulerian coupling enabling solid transport simulation under both continuum and discrete approaches, and has been validated with both laboratory data and paleo-tsunami evidence (Conde, 2013a; Conde, 2013b). The interactions between the inundating flow and coal stockpiles or natural mobile bed reaches were simulated using a continuum debris-flow approach, featuring fractional solid transport, while the containers at the new terminal were advected with an explicit Lagrangian method. The meshwork employed at the port models the existing geometry and structures in great detail, enabling explicitly resolved interactions between the current infrastructure and the overland propagating tsunami. The obtained preliminary results suggest that several structures, some of them critical in a nationwide context, are exposed to tsunami actions. The coal deposition pattern and the final location of monitored containers were determined for two magnitude scenarios (8.5 Mw and 9.5 Mw) in the case of a tsunami generated at the Horseshoe fault and one magnitude scenario (9.5 Mw) for a tsunami generated at the Gorringe bank. The inland washing of the coal stockpiles may impose great loss of both economical and environmental value, while the impact of large mobile debris, such as the containers in the terminal area, significantly increases the severity of infrastructural damage.

    Full Text Available The minimization of power in wireless sensor network is big issue. If the process of energy constraints is optimized increase the reliability and security of mobile ADHOC network. The management of ADHOC network is great challenge due to dynamic infrastructure and mobility of node. Due to mobility of node routing path of network and security of communication suffered. In the process of node mobility and path discovery of routing protocol take huge amount of power and decrease the life of network. For the improvement of power and secured communication various protocol are designed but all are limitation in terms of group communication in ADHOC network. A security constraint in mobile ADHOC network is very critical task. Some critical security issue such as black hole attack, wormhole attack, sinkhole attack, prevention and detection of attack is major challenge. For the detection of wormhole attack various authors used various technique such as clock synchronization, threshold based technique, nearest neighbor node selection method.

    In several critical infrastructures correlations between the constituent systems represent certain vulnerabilities: disruptions to one may propagate to others and possibly to the entire infrastructure. The correlations between the systems are characterized in two ways in this paper: (i) the aggregate failure correlation function specifies the conditional failure probability of the infrastructure given the failure of an individual system, and (ii) the pairwise correlation function between two systems specifies the failure probability of one system given the failure of the other. The survival probabilities of individual systems satisfy firstorder differential conditions that generalize the contest success functions and statistical independence conditions. We formulate a problem of ensuring the resilience of an infrastructure as a game between the provider and attacker; their utility functions are sums of infrastructure survival probability terms and cost terms, both expressed in terms of the numbers of system components attacked and reinforced. We derive Nash Equilibrium conditions and sensitivity functions that highlight the dependence of infrastructure resilience on the cost terms, correlation functions, and individual system survival probabilities. We apply these results to models of distributed cloud computing and energy grid infrastructures.

    2016-04-01

    The adoption of smart meters, distributed sensor networks and industrial control systems has largely improved the level of service provided by modern water supply systems. Yet, the progressive computerization exposes these critical infrastructures to cyber-physical attacks, which are generally aimed at stealing critical information (cyber-espionage) or causing service disruption (denial-of-service). Recent statistics show that water and power utilities are undergoing frequent attacks - such as the December power outage in Ukraine - , attracting the interest of operators and security agencies. Taking the security of Water Distribution Networks (WDNs) as domain of study, our work seeks to characterize the vulnerability of WDNs to cyber-physical attacks, so as to conceive adequate defense mechanisms. We extend the functionality of EPANET, which models hydraulic and water quality processes in pressurized pipe networks, to include a cyber layer vulnerable to repeated attacks. Simulation results on a medium-scale network show that several hydraulic actuators (valves and pumps, for example) can be easily attacked, causing both service disruption - i.e., water spillage and loss of pressure - and structural damages - e.g., pipes burst. Our work highlights the need for adequate countermeasures, such as attacks detection and reactive control systems.

  10. Critical analysis of the Bennett-Riedel attack on secure cryptographic key distributions via the Kirchhoff-Law-Johnson-noise scheme.

    Directory of Open Access Journals (Sweden)

    Laszlo B Kish

    Full Text Available Recently, Bennett and Riedel (BR (http://arxiv.org/abs/1303.7435v1 argued that thermodynamics is not essential in the Kirchhoff-law-Johnson-noise (KLJN classical physical cryptographic exchange method in an effort to disprove the security of the KLJN scheme. They attempted to demonstrate this by introducing a dissipation-free deterministic key exchange method with two batteries and two switches. In the present paper, we first show that BR's scheme is unphysical and that some elements of its assumptions violate basic protocols of secure communication. All our analyses are based on a technically unlimited Eve with infinitely accurate and fast measurements limited only by the laws of physics and statistics. For non-ideal situations and at active (invasive attacks, the uncertainly principle between measurement duration and statistical errors makes it impossible for Eve to extract the key regardless of the accuracy or speed of her measurements. To show that thermodynamics and noise are essential for the security, we crack the BR system with 100% success via passive attacks, in ten different ways, and demonstrate that the same cracking methods do not function for the KLJN scheme that employs Johnson noise to provide security underpinned by the Second Law of Thermodynamics. We also present a critical analysis of some other claims by BR; for example, we prove that their equations for describing zero security do not apply to the KLJN scheme. Finally we give mathematical security proofs for each BR-attack against the KLJN scheme and conclude that the information theoretic (unconditional security of the KLJN method has not been successfully challenged.

    2015-08-01

    The United States' power infrastructure is aging, underfunded, and vulnerable to cyber attack. Emerging smart grid technologies may take some of the burden off of existing systems and make the grid as a whole more efficient, reliable, and secure. The Pacific Northwest National Laboratory (PNNL) is funding research into several aspects of smart grid technology and grid security, creating a software simulation tool that will allow researchers to test power infrastructure control and distribution paradigms by utilizing different smart grid technologies to determine how the grid and these technologies react under different circumstances. Understanding how these systems behave in real-world conditions will lead to new ways to make our power infrastructure more resilient and secure. Demonstrating security in embedded systems is another research area PNNL is tackling. Many of the systems controlling the U.S. critical infrastructure, such as the power grid, lack integrated security and the aging networks protecting them are becoming easier to attack.

    Full Text Available Industrial Control Systems (ICS are open to security attacks when they are integrated with IT systems and wireless technologies for enhanced processing and remote control. These Critical Infrastructures (CIs are highly important as they provide service for an entire nation and causes serious danger even when interrupted for a while. Some of the common SCADA (Supervisory Control and Data Acquisition systems involve energy and water distribution systems. In this paper, the energy distribution SCADA system comprising several substations is considered. A secure framework is proposed that combines the energy control system with Wireless Sensor Networks (WSNs, Mobile Ad hoc Networks (MANETs, and the Internet, providing anomaly prevention and status management. SCADA attacks occur at the state estimators of the power systems which are used to route power flows and detect faulty devices. These estimators are located in the SCADA control center which is a sensitive area and measurements must be transmitted over a secure communication channel. The attack-resistance of the SCADA system is enhanced by increasing the hardness and complexity of the attack problem. The Attack-Resistant and Secure (ARS SCADA system is evaluated against existing techniques like NAMDIA (Network-Aware Mitigation of Data Integrity Attacks, Retrofit IDS (Intrusion Detection System, and CSBF (Critical State-Based Filtering for enhancing the attack-resistance and security of SCADA systems. It is found that the performance of ARS SCADA system is good compared to the existing methods in terms of maximum normalized attack impact and latency.

    During the 2011 Mississippi River Basin flood, the U.S. Geological Survey evaluated aspects of critical river infrastructure at the request of and in support of local, State, and Federal Agencies. Geotechnical and hydrographic data collected by the U.S. Geological Survey at numerous locations were able to provide needed information about 2011 flood effects to those managing the critical infrastructure. These data were collected and processed in a short time frame to provide managers the ability to make a timely evaluation of the safety of the infrastructure and, when needed, to take action to secure and protect critical infrastructure. Critical infrastructure surveyed by the U.S. Geological Survey included levees, bridges, pipeline crossings, power plant intakes and outlets, and an electrical transmission tower. Capacitively coupled resistivity data collected along the flood-protection levees surrounding the Omaha Public Power District Nebraska City power plant (Missouri River Levee Unit R573), mapped the near-subsurface electrical properties of the levee and the materials immediately below it. The near-subsurface maps provided a better understanding of the levee construction and the nature of the lithology beneath the levee. Comparison of the capacitively coupled resistivity surveys and soil borings indicated that low-resistivity value material composing the levee generally is associated with lean clay and silt to about 2 to 4 meters below the surface, overlying a more resistive layer associated with sand deposits. In general, the resistivity structure becomes more resistive to the south and the southern survey sections correlate well with the borehole data that indicate thinner clay and silt at the surface and thicker sand sequences at depth in these sections. With the resistivity data Omaha Public Power District could focus monitoring efforts on areas with higher resistivity values (coarser-grained deposits or more loosely compacted section), which typically are

    Resilient PV, which is solar paired with storage ('solar-plus-storage'), provides value both during normal grid operation and power outages as opposed to traditional solar PV, which functions only when the electric grid is operating. During normal grid operations, resilient PV systems help host sites generate revenue and/or reduce electricity bill charges. During grid outages, resilient PV provides critical emergency power that can help people in need and ease demand on emergency fuel supplies. The combination of grid interruptions during recent storms, the proliferation of solar PV, and the growing deployment of battery storage technologies has generated significant interest in using these assets for both economic and resiliency benefits. This report analyzes the technical and economic viability for resilient PV on three critical infrastructure sites in New York City (NYC): a school that is part of a coastal storm shelter system, a fire station, and a NYCHA senior center that serves as a cooling center during heat emergencies. This analysis differs from previous solar-plus-storage studies by placing a monetary value on resiliency and thus, in essence, modeling a new revenue stream for the avoided cost of a power outage. Analysis results show that resilient PV is economically viable for NYC's critical infrastructure and that it may be similarly beneficial to other commercial buildings across the city. This report will help city building owners, managers, and policymakers better understand the economic and resiliency benefits of resilient PV. As NYC fortifies its building stock against future storms of increasing severity, resilient PV can play an important role in disaster response and recovery while also supporting city greenhouse gas emission reduction targets and relieving stress to the electric grid from growing power demands.

  3. Making green infrastructure healthier infrastructure

    2015-11-01

    Full Text Available Increasing urban green and blue structure is often pointed out to be critical for sustainable development and climate change adaptation, which has led to the rapid expansion of greening activities in cities throughout the world. This process is likely to have a direct impact on the citizens’ quality of life and public health. However, alongside numerous benefits, green and blue infrastructure also has the potential to create unexpected, undesirable, side-effects for health. This paper considers several potential harmful public health effects that might result from increased urban biodiversity, urban bodies of water, and urban tree cover projects. It does so with the intent of improving awareness and motivating preventive measures when designing and initiating such projects. Although biodiversity has been found to be associated with physiological benefits for humans in several studies, efforts to increase the biodiversity of urban environments may also promote the introduction and survival of vector or host organisms for infectious pathogens with resulting spread of a variety of diseases. In addition, more green connectivity in urban areas may potentiate the role of rats and ticks in the spread of infectious diseases. Bodies of water and wetlands play a crucial role in the urban climate adaptation and mitigation process. However, they also provide habitats for mosquitoes and toxic algal blooms. Finally, increasing urban green space may also adversely affect citizens allergic to pollen. Increased awareness of the potential hazards of urban green and blue infrastructure should not be a reason to stop or scale back projects. Instead, incorporating public health awareness and interventions into urban planning at the earliest stages can help insure that green and blue infrastructure achieves full potential for health promotion.

    Full Text Available Wormhole attacks enable an attacker with limited Resources and no cryptographic material to wreak havoc on wireless networks. Initial research focused that this attack is possible only on Adhoc networks, but in present condition wormhole attack is possible on infrastructure based wireless LANs also. We propose architecture and analyze the possibility of wormhole attack along with a countermeasure to avoid such an attack. The proposed mechanism involves the shared information between communicating Access Points to prevent Rouge Access Points from masquerading as false neighbours. Our defense greatly diminishes the threat of wormhole attacks and requires no location information or clock synchronization.

    Threat characterization is a key component in evaluating the threat faced by control systems. Without a thorough understanding of the threat faced by critical infrastructure networks, adequate resources cannot be allocated or directed effectively to the defense of these systems. Traditional methods of threat analysis focus on identifying the capabilities and motivations of a specific attacker, assessing the value the adversary would place on targeted systems, and deploying defenses according to the threat posed by the potential adversary. Too many effective exploits and tools exist and are easily accessible to anyone with access to an Internet connection, minimal technical skills, and a significantly reduced motivational threshold to be able to narrow the field of potential adversaries effectively. Understanding how hackers evaluate new IT security research and incorporate significant new ideas into their own tools provides a means of anticipating how IT systems are most likely to be attacked in the future. This research, Attack Methodology Analysis (AMA), could supply pertinent information on how to detect and stop new types of attacks. Since the exploit methodologies and attack vectors developed in the general Information Technology (IT) arena can be converted for use against control system environments, assessing areas in which cutting edge exploit development and remediation techniques are occurring can provide significance intelligence for control system network exploitation, defense, and a means of assessing threat without identifying specific capabilities of individual opponents. Attack Methodology Analysis begins with the study of what exploit technology and attack methodologies are being developed in the Information Technology (IT) security research community within the black and white hat community. Once a solid understanding of the cutting edge security research is established, emerging trends in attack methodology can be identified and the gap between

    Design, construction, maintenance and upgrading of civil engineering infrastructure requires fresh thinking to minimize use of materials, energy and labour. This can only be achieved by understanding the performance of the infrastructure, both during its construction and throughout its design life, through innovative monitoring. Advances in sensor systems offer intriguing possibilities to radically alter methods of condition assessment and monitoring of infrastructure. In this paper, it is hypothesized that the future of infrastructure relies on smarter information; the rich information obtained from embedded sensors within infrastructure will act as a catalyst for new design, construction, operation and maintenance processes for integrated infrastructure systems linked directly with user behaviour patterns. Some examples of emerging sensor technologies for infrastructure sensing are given. They include distributed fibre-optics sensors, computer vision, wireless sensor networks, low-power micro-electromechanical systems, energy harvesting and citizens as sensors.

    From transportation networks to complex infrastructures, and to social and economic networks, a large variety of systems can be described in terms of multiplex networks formed by a set of nodes interacting through different network layers. Network robustness, as one of the most successful application areas of complex networks, has attracted great interest in a myriad of research realms. In this regard, how multiplex networks respond to potential attack is still an open issue. Here we study the robustness of multiplex networks under layer node-based random or targeted attack, which means that nodes just suffer attacks in a given layer yet no additional influence to their connections beyond this layer. A theoretical analysis framework is proposed to calculate the critical threshold and the size of giant component of multiplex networks when nodes are removed randomly or intentionally. Via numerous simulations, it is unveiled that the theoretical method can accurately predict the threshold and the size of giant component, irrespective of attack strategies. Moreover, we also compare the robustness of multiplex networks under multiplex node-based attack and layer node-based attack, and find that layer node-based attack makes multiplex networks more vulnerable, regardless of average degree and underlying topology.

    The robustness of a network of networks (NON) under random attack has been studied recently [Gao , Phys. Rev. Lett.PRLTAO0031-900710.1103/PhysRevLett.107.195701 107, 195701 (2011)]. Understanding how robust a NON is to targeted attacks is a major challenge when designing resilient infrastructures. We address here the question how the robustness of a NON is affected by targeted attack on high- or low-degree nodes. We introduce a targeted attack probability function that is dependent upon node degree and study the robustness of two types of NON under targeted attack: (i) a tree of n fully interdependent Erdős-Rényi or scale-free networks and (ii) a starlike network of n partially interdependent Erdős-Rényi networks. For any tree of n fully interdependent Erdős-Rényi networks and scale-free networks under targeted attack, we find that the network becomes significantly more vulnerable when nodes of higher degree have higher probability to fail. When the probability that a node will fail is proportional to its degree, for a NON composed of Erdős-Rényi networks we find analytical solutions for the mutual giant component P∞ as a function of p, where 1-p is the initial fraction of failed nodes in each network. We also find analytical solutions for the critical fraction pc, which causes the fragmentation of the n interdependent networks, and for the minimum average degree k¯min below which the NON will collapse even if only a single node fails. For a starlike NON of n partially interdependent Erdős-Rényi networks under targeted attack, we find the critical coupling strength qc for different n. When q>qc, the attacked system undergoes an abrupt first order type transition. When q≤qc, the system displays a smooth second order percolation transition. We also evaluate how the central network becomes more vulnerable as the number of networks with the same coupling strength q increases. The limit of q=0 represents no dependency, and the results are consistent with

    2014-01-01

    The robustness of complex networks against node failure and malicious attack has been of interest for decades, while most of the research has focused on random attack or hub-targeted attack. In many real-world scenarios, however, attacks are neither random nor hub-targeted, but localized, where a group of neighboring nodes in a network are attacked and fail. In this paper we develop a percolation framework to analytically and numerically study the robustness of complex networks against such localized attack. In particular, we investigate this robustness in Erd\\H{o}s-R\\'{e}nyi networks, random-regular networks, and scale-free networks. Our results provide insight into how to better protect networks, enhance cybersecurity, and facilitate the design of more robust infrastructures.

    Full Text Available Public-private cooperation on the level of project finance, and provision of large-scale infrastructure projects, is increasing on the global level. This paper uses a multi-actor analysis, in order to explore the critical success factors (CSFs for sound implementation of public-private partnerships (PPPs in the port context, and to determine the diverging opinions of stakeholders with regard to the importance of these CSFs. The results indicate that eight CSFs are of superior importance in port PPPs: the concreteness and preciseness of the concession agreement, the ability to appropriately allocate and share risk, the technical feasibility of the project, the commitment made by partners, the attractiveness of the financial package, a clear definition of responsibilities, the presence of a strong private consortium and a realistic cost/benefit assessment. The reason for their importance is their deal-breaking character, which can lead to a total failure of PPP projects during the early stages of project conception.

    2012-01-01

    Cyber security for industrial control systems has received significant attention in the past two years. The news coverage of the Stuxnet attack, believed to be targeted at the control system for a uranium enrichment plant, brought the issue to the attention of news media and policy makers. This has led to increased scrutiny of control systems for critical infrastructure such as power generation and distribution, and industrial systems such as chemical plants and petroleum refineries. The past two years have also seen targeted network attacks aimed at corporate and government entities including US Department of Energy National Laboratories. Both of these developments have potential repercussions for the control systems of particle accelerators. The need to balance risks from potential attacks with the operational needs of an accelerator present a unique challenge for the system architecture and access model.

    Full Text Available The Internet threat monitoring (ITM systems have been deployed to detect widespread attacks on the Internet in recent years. However, the effectiveness of ITM systems critically depends on the confidentiality of the location of their monitors. If adversaries learn the monitor locations of an ITM system, they can bypass the monitors and focus on the uncovered IP address space without being detected. In this paper, we study a new class of attacks, the invisible LOCalization (iLOC attack. The iLOC attack can accurately and invisibly localize monitors of ITM systems. In the iLOC attack, the attacker launches low-rate port-scan traffic, encoded with a selected pseudo noise code (PN-code, to targeted networks. While the secret PN-code is invisible to others, the attacker can accurately determine the existence of monitors in the targeted networks based on whether the PN-code is embedded in the report data queried from the data center of the ITM system. We formally analyze the impact of various parameters on attack effectiveness. We implement the iLOC attack and conduct the performance evaluation on a real-world ITM system to demonstrate the possibility of such attacks. We also conduct extensive simulations on the iLOC attack using real-world traces. Our data show that the iLOC attack can accurately identify monitors while being invisible to ITM systems. Finally, we present a set of guidelines to counteract the iLOC attack.

    Unprecedented growth of required telecommunications services and telecommunications applications change the way the INL does business today. High speed connectivity compiled with a high demand for telephony and network services requires a robust communications infrastructure.   The current state of the MFC communication infrastructure limits growth opportunities of current and future communication infrastructure services. This limitation is largely due to equipment capacity issues, aging cabling infrastructure (external/internal fiber and copper cable) and inadequate space for telecommunication equipment. While some communication infrastructure improvements have been implemented over time projects, it has been completed without a clear overall plan and technology standard.   This document identifies critical deficiencies with the current state of the communication infrastructure in operation at the MFC facilities and provides an analysis to identify needs and deficiencies to be addressed in order to achieve target architectural standards as defined in STD-170. The intent of STD-170 is to provide a robust, flexible, long-term solution to make communications capabilities align with the INL mission and fit the various programmatic growth and expansion needs.

    Full Text Available Mobile Ad-hoc NETwork (MANET is an application of wireless network with self-configuring mobile nodes. MANET does not require any fixed infrastructure. Its development never has any threshold range. Nodes in MANET can communicate with each other if and only if all the nodes are in the same range. This wide distribution of nodes makes MANET vulnerable to various attacks, packet dropping attack or black hole attack is one of the possible attack. It is very hard to detect and prevent. To prevent from packet dropping attack, detection of misbehavior links and selfish nodes plays a vital role in MANETs. In this paper, a omprehensive investigation on detection of misbehavior links and malicious nodes is carried out.

    This paper investigates collaborative cyber attacks based on social network analysis. An Attack Social Graph (ASG) is defined to represent cyber attacks on the Internet. Features are extracted from ASGs to analyze collaborative patterns. We use principle component analysis to reduce the feature space, and hierarchical clustering to group attack sources that exhibit similar behavior. Experiments with real world data illustrate that our framework can effectively reduce from large dataset to clusters of attack sources exhibiting critical collaborative patterns.

    RFID systems became widespread in variety of applications because of their simplicity in manufacturing and usability. In the province of critical infrastructure protection, RFID systems are usually employed to identify and track people, objects and vehicles that enter restricted areas. The most important vulnerability which is prevalent among all protocols employed in RFID systems is against relay attacks. Until now, to protect RFID systems against this kind of attack, the only approach is the utilization of distance-bounding protocols which are not applicable over low-cost devices such as RFID passive tags. This work presents a novel technique using emerging quantum technologies to detect relay attacks on RFID systems. Recently, it is demonstrated that quantum key distribution (QKD) can be implemented in a client-server scheme where client only requires an on-chip polarization rotator that may be integrated into a handheld device. Now we present our technique for a tag-reader scenario which needs similar resources as the mentioned QKD scheme. We argue that our technique requires less resources and provides lower probability of false alarm for the system, compared with distance-bounding protocols, and may pave the way to enhance the security of current RFID systems.

  11. Revisiting the Estonian Cyber Attacks: Digital Threats and Multinational Responses

    2011-01-01

    Full Text Available In April 2007, the Estonian Government moved a memorial commemorating the Soviet liberation of the country from the Nazis to a less prominent and visible location in Tallinn. This decision triggered rioting among Russian-speaking minorities and cyber terrorism targeting Estonia's critical economic and political infrastructure. Drawing upon the Estonian cyber attacks, this article argues that globalization and the Internet have enabled transnational groups—such as the Russian diaspora—to avenge their grievances by threatening the sovereignty of nation-states in cyberspace. Sophisticated and virtually untraceable political "hacktivists" may now possess the ability to disrupt or destroy government operations, banking transactions, city power grids, and even military weapon systems. Fortunately, western countries banded together to effectively combat the Estonian cyber attacks and minimize their effects. However, this article concludes that in the age of globalization, interdependence, and digital interconnectedness, nation-states must engage in increased cooperative cyber-defense activities to counter and prevent devastating Internet attacks and their implications.

    2000-01-06

    The executive branch of the United States government has acknowledged and identified threats to the water supply infrastructure of the United States. These threats include contamination of the water supply, aging infrastructure components, and malicious attack. Government recognition of the importance of providing safe, secure, and reliable water supplies has a historical precedence in the water works of the ancient Romans, who recognized the same basic threats to their water supply infrastructure the United States acknowledges today. System surety is the philosophy of ''designing for threats, planning for failure, and managing for success'' in system design and implementation. System surety is an alternative to traditional compliance-based approaches to safety, security, and reliability. Four types of surety are recognized: reactive surety; proactive surety, preventative surety; and fundamental, inherent surety. The five steps of the system surety approach can be used to establish the type of surety needed for the water infrastructure and the methods used to realize a sure water infrastructure. The benefit to the water industry of using the system surety approach to infrastructure design and assessment is a proactive approach to safety, security, and reliability for water transmission, treatment, distribution, and wastewater collection and treatment.

  15. INTRUSION DETECTION IN MOBILE AD HOC NETWORK USING SECURE ROUTING FOR ATTACKER IDENTIFICATION PROTOCOL

    Directory of Open Access Journals (Sweden)

    S. Gopalakrishnan

    2014-01-01

    Full Text Available In past few decades, the migration of communication takes place from wired networks to wireless networks because of its mobility and scalability and Mobile Ad hoc Network (MANET is a unique and significant application in recent years which does not necessitates any pre-existing network infrastructure. Each node can act as both transmitters as well as receivers that are communicating with each other when they are in same communication/transmission range. Otherwise, these nodes depend on neighbor nodes to transmit their packets and they possess self-configuring ability which makes MANETs popular in various critical mission applications such as military and other emergency applications. In general, MANETs are open medium network and their nodes are widely distributed which makes the network more vulnerable to various attackers. Some times, the transmitted packets are viewed or modified or corrupted by the attackers through the way to reach destination and the destination could not find such type of packets. So, the receiver can deliver modified packets with wrong information. Thus, it is essential to present an efficient secure routing protocol to preserve MANET from several attacks. In this study, we are going to propose and implement a novel routing protocol named Secure Routing for Attacker Identification (SRAI protocol that executes at receiver/destination side to discover the modified packets in delivered nodes and generate misbehaviour report to the source. Compared to modern approaches, SRAI protocol establishes higher attacker identification rates in certain considerations.

    Full Text Available Mobile Ad-Hoc networks are self-configuring and self-organizing multi-hop wireless networks. They do not have any fixed infrastructure or centralized management. Due to this, the ad hoc networks are vulnerable to attacks. The routing protocol for MANET considered in this paper is AODV(Ad hoc On-demand Distance Vector Routing Protocol. Blackhole and Wormhole nodes are malicious nodeswhich degrade the performance of the network. They actively participate in the network and conform to forward packets to the destination. The Watchdog Mechanism is used to correct the network from both blackhole and wormhole attacks. The networks originally, with the attacks and after being prevented from attacks are compared on the basis of packets received, throughput, end-to-end delay and packet delivery ratio. ns2 software is used for the simulation.

    2013-01-01

    Full Text Available Mobile Ad hoc Networks (MANET are easily prone to attacks due to its network infrastructure. In previous routing attacks the malicious node is isolated using naive fuzzy response decisions. In this paper a new technology of broadcasting the awareness information about attacker node to all the existing nodes in the network is discussed. The awareness approach is based on an extended Dempster-Shafer mathematical theory(D-S Theory. Dempster-Shafer mathematical theory is used to collect the evidence notion of importance factors. The adaptiveness of the mechanism allows to systematically cope with the identified MANET routing attacks. The intrusion response action in MANET was addressed by isolating uncooperative nodes based on the node reputation derived from their behaviors. Here the effectiveness of the approach with the consideration of the packet delivery ratio and routing cost were demonstrated using java swing concepts

    In most organizations, IT (information technology) infrastructure exists to support the organization's mission. The threat of cyber attacks poses risks to this mission. Current network security research focuses on the threat of cyber attacks to the organization's IT infrastructure; however, the risks to the overall mission are rarely analyzed or formalized. This connection of IT infrastructure to the organization's mission is often neglected or carried out ad-hoc. Our work bridges this gap and introduces analyses and formalisms to help organizations understand the mission risks they face from cyber attacks. Modeling an organization's mission vulnerability to cyber attacks requires a description of the IT infrastructure (network model), the organization mission (business model), and how the mission relies on IT resources (correlation model). With this information, proper analysis can show which cyber resources are of tactical importance in a cyber attack, i.e., controlling them enables a large range of cyber attacks. Such analysis also reveals which IT resources contribute most to the organization's mission, i.e., lack of control over them gravely affects the mission. These results can then be used to formulate IT security strategies and explore their trade-offs, which leads to better incident response. This paper presents our methodology for encoding IT infrastructure, organization mission and correlations, our analysis framework, as well as initial experimental results and conclusions.

Based on maps of a socio......-technical system, the attack navigator identifies routes to an attacker goal. Specific attacker properties such as skill or resources can be included through attacker profiles. This enables defenders to explore attack scenarios and the effectiveness of defense alternatives under different threat conditions....

  4. Vulnerabilities of the security of nuclear material due to cyber attacks

    International Nuclear Information System (INIS)

    Full text: The spread of new communication and computer technologies is now the potential for a dedicated, sophisticated adversary to conduct coordinated strikes against the computers, communications systems, and databases of nuclear material security systems. All weapons of cyber war, like viruses, Trojans, access to computer systems are potential risks for the security of nuclear material. New forms of destruction of electronic devices, e.g. Transient Electromagnetic Devices (TED), that could, in the hands of enemies, criminals, or terrorist pose a significant threat to nuclear safety infrastructure components that are based on micro-circuits and computer or micro-processor control. These examples shows the necessity to clearly identify possible risks as: information and communication based disorders and other disruptions and attacks; partial or complete failure of systems causing the risk of unexpected reaction or unmanageable situations; cracking of access codes and elimination of alarm equipment could give easy access to nuclear material; computer manipulation or complete computer and system takeover due to brute force attacks, viruses, Trojans and worms could lead to malfunctions, disruptions and nuclear disasters; computer spying and brute force attacks could give detailed information about technical, organizational and organizational data; combined actions of physical, electronic and computer attacks. The paper gives an overview of potential computer and communication safety gaps and points out strategic implications as the identification of the critical infrastructure, surveillance of computer systems, data access and communication paths. The basic necessity of the development of computer and communication breakdown backup systems as well as measures of precaution against cyber attacks is shown in the paper. (author)

    Happenny, Sean F. [Pacific Northwest National Lab. (PNNL), Richland, WA (United States)

    2015-08-01

    The United States’ power infrastructure is aging, underfunded, and vulnerable to cyber attack. Emerging smart grid technologies may take some of the burden off of existing systems and make the grid as a whole more efficient, reliable, and secure. The Pacific Northwest National Laboratory (PNNL) is funding research into several aspects of smart grid technology and grid security, creating a software simulation tool that will allow researchers to test power distribution networks utilizing different smart grid technologies to determine how the grid and these technologies react under different circumstances. Demonstrating security in embedded systems is another research area PNNL is tackling. Many of the systems controlling the U.S. critical infrastructure, such as the power grid, lack integrated security and the networks protecting them are becoming easier to breach. Providing a virtual power substation network to each student team at the National Collegiate Cyber Defense Competition, thereby supporting the education of future cyber security professionals, is another way PNNL is helping to strengthen the security of the nation’s power infrastructure.

  8. Composite Dos Attack Model

    2012-04-01

    Full Text Available Preparation for potential threats is one of the most important phases ensuring system security. It allows evaluating possible losses, changes in the attack process, the effectiveness of used countermeasures, optimal system settings, etc. In cyber-attack cases, executing real experiments can be difficult for many reasons. However, mathematical or programming models can be used instead of conducting experiments in a real environment. This work proposes a composite denial of service attack model that combines bandwidth exhaustion, filtering and memory depletion models for a more real representation of similar cyber-attacks. On the basis of the introduced model, different experiments were done. They showed the main dependencies of the influence of attacker and victim’s properties on the success probability of denial of service attack. In the future, this model can be used for the denial of service attack or countermeasure optimization.

  10. Towards risk-based management of critical infrastructures : enabling insights and analysis methodologies from a focused study of the bulk power grid.

    Energy Technology Data Exchange (ETDEWEB)

    Richardson, Bryan T.; LaViolette, Randall A.; Cook, Benjamin Koger

    2008-02-01

    This report summarizes research on a holistic analysis framework to assess and manage risks in complex infrastructures, with a specific focus on the bulk electric power grid (grid). A comprehensive model of the grid is described that can approximate the coupled dynamics of its physical, control, and market components. New realism is achieved in a power simulator extended to include relevant control features such as relays. The simulator was applied to understand failure mechanisms in the grid. Results suggest that the implementation of simple controls might significantly alter the distribution of cascade failures in power systems. The absence of cascade failures in our results raises questions about the underlying failure mechanisms responsible for widespread outages, and specifically whether these outages are due to a system effect or large-scale component degradation. Finally, a new agent-based market model for bilateral trades in the short-term bulk power market is presented and compared against industry observations.

  11. Use of Attack Graphs in Security Systems

    2014-01-01

    Full Text Available Attack graphs have been used to model the vulnerabilities of the systems and their potential exploits. The successful exploits leading to the partial/total failure of the systems are subject of keen security interest. Considerable effort has been expended in exhaustive modeling, analyses, detection, and mitigation of attacks. One prominent methodology involves constructing attack graphs of the pertinent system for analysis and response strategies. This not only gives the simplified representation of the system, but also allows prioritizing the security properties whose violations are of greater concern, for both detection and repair. We present a survey and critical study of state-of-the-art technologies in attack graph generation and use in security system. Based on our research, we identify the potential, challenges, and direction of the current research in using attack graphs.

  12. Scenario Planning to Address Critical Uncertainties for Robust and Resilient Water–Wastewater Infrastructures under Conditions of Water Scarcity and Rapid Development

    Directory of Open Access Journals (Sweden)

    Kerri Jean Ormerod

    2012-11-01

    Full Text Available Ensuring water availability for multiple needs represents a sustainable development challenge globally. Rigid planning for fixed water supply and reuse targets with estimated demand growth and static assumptions of water availability can prove inflexible in responding to changing conditions. Formal methods to adaptively respond to these challenges are needed, particularly in regions with limited natural resources and/or where multiple uncertain forces can influence water-resource availability and supply reliability. This paper assesses the application of Scenario Planning in one such region—Tucson, Arizona, USA—over the coming 40 years, and highlights broader lessons for addressing complex interrelationships of water management, infrastructure development, and population growth. Planners from multiple jurisdictions and researchers identified ten key forces and prioritized three with the greatest uncertainty and the greatest impact for water and development planning: (1 changing demands based on potential future density, layout, and per capita water use/reuse; (2 adequacy of current water supplies to meet future demands; and (3 evolving public perceptions of water reuse including potential options to supplement potable water supplies. Detailed scenario modeling using GIS and infrastructure cost optimization is under development and is now beginning to produce results, to be discussed in future publications. The process has clearly demonstrated the value of Scenario Planning as a tool for bringing stakeholders into agreement over highly complex and historically divisive problems, and for prioritizing amongst diverse uncertainties. The paper concludes by characterizing possible outcomes for this case and draws lessons for other water scarce regions experiencing rapid development.

    2016-07-01

    Full Text Available lack of infrastructure in ad hoc networks makes their deployment easier. Each node in an ad hoc network can route data using a routing protocol, which decreases the level of security. Ad hoc networks are exposed to several attacks such as the blackhole attack. In this article, a study has been made on the impact of the attack on the hybrid routing protocol ZRP (Zone Routing Protocol. In this attack a malicious node is placed between two or more nodes in order to drop data. The trick of the attack is simple, the malicious node declares to have the most reliable way to the destination so that the wife destination chooses this path. In this study, NS2 is used to assess the impact of the attack on ZRP. Two metrics measure, namely the packet delivered ratio and end to end delay.

  17. Performance Analysis of Manet Before and After Black Hole Attack

    2012-01-01

    Full Text Available A Mobile ad-hoc network is a temporary network set up by wireless mobile computers (or nodes moving arbitrary in the places that have no network infrastructure. Due to security vulnerabilities of the routing protocols, wireless ad-hoc networks are unprotected to attacks of the malicious nodes. One of the prominent attacks is the Black Hole Attack which absorbs all data packets in the network. Since the data packets do not reach the destination node on account of this attack, data loss will occur. In this paper we simulated MANETs with and without Black Hole to study the effects of Black hole attack on network performance. Because of Black Hole Attack the average packet drop increased form 0.25% to 90.69% . The throughput of the network decreased 93.56% due to Black Hole effect.

  18. Mining IP to Domain Name Interactions to Detect DNS Flood Attacks on Recursive DNS Servers

    Directory of Open Access Journals (Sweden)

    Roberto Alonso

    2016-08-01

    Full Text Available The Domain Name System (DNS is a critical infrastructure of any network, and, not surprisingly a common target of cybercrime. There are numerous works that analyse higher level DNS traffic to detect anomalies in the DNS or any other network service. By contrast, few efforts have been made to study and protect the recursive DNS level. In this paper, we introduce a novel abstraction of the recursive DNS traffic to detect a flooding attack, a kind of Distributed Denial of Service (DDoS. The crux of our abstraction lies on a simple observation: Recursive DNS queries, from IP addresses to domain names, form social groups; hence, a DDoS attack should result in drastic changes on DNS social structure. We have built an anomaly-based detection mechanism, which, given a time window of DNS usage, makes use of features that attempt to capture the DNS social structure, including a heuristic that estimates group composition. Our detection mechanism has been successfully validated (in a simulated and controlled setting and with it the suitability of our abstraction to detect flooding attacks. To the best of our knowledge, this is the first time that work is successful in using this abstraction to detect these kinds of attacks at the recursive level. Before concluding the paper, we motivate further research directions considering this new abstraction, so we have designed and tested two additional experiments which exhibit promising results to detect other types of anomalies in recursive DNS servers.

    Dry, Carolyn

    2007-04-01

    The goal of our research has been to develop self-repairing matrices with unique toughness and strength for infrastructure and vehicles. Our revolutionary approach involves the autonomous release of repair chemicals from within the matrix itself. The repair agents are contained in hollow, structural fibers or beads that are embedded within the matrix. Under stress, the matrix senses external environmental factors and reacts by releasing the repair agents from within the hollow vessels. This autonomous response occurs wherever and whenever cracking, debonding or other matrix damage transpires. Superior performance over the life of the matrix is achieved through this self-repairing mechanism. The advantages are safely executed trips, fewer repairs and eventually lighter bridges and vehicles. Research to assess and clarify the impact of the various factors involved in self-repair of matrix materials has been the focus of our work for several years. Our research has addressed the issues by correlating the impact of the various factors, such as 1) delivery vessel, shape/size, coating, chemicals released, release trigger and efficacy and impact on matrix properties 2) influence of end use such as the importance of speed and force of release (airplane skin repair) 3) impact of processing methods that involve heat and pressure on the repair vessels. Our self repairing system can: be processed at temperatures of 350F, repairs in less than 30 seconds, and does not damage the matrix by repair fiber insertion. Unique toughness and strength is developed at damaged areas and material interfaces. Findings are based on testing in compression after impact, compression, fatigue, flexural toughness and flexure modes. The presentation will focus on highlighting the issues that were resolved in creating autonomous, self-repairing structures and vehicles.

  8. Secluding Efficient Geographic Multicast Protocol against Multicast Attacks

    2013-09-01

    Full Text Available A Mobile Ad-hoc Network (MANETs is composed of Mobile Nodes without any infrastructure. The network nodes in MANETs, not only act as ordinary network nodes but also as the routers for other peer devices. The dynamic topology, lack of a fixed infrastructure and the wireless nature make MANETs susceptible to the security attacks. To add to that, due to the inherent, severe constraints in power, storage and computational resources in the MANET nodes, incorporating sound defense mechanisms against such attacks is also non-trivial. Therefore, interest in research of Mobile Ad-hoc NETworks has been growing since last few years. Security is a big issue in MANETs as they are infrastructure-less and autonomous. The main objective of this paper is to address some basic security concerns in EGMP protocol which is a multicast protocol found to be more vulnerable towards attacks like blackhole, wormhole and flooding attacks. The proposed technique uses the concepts of certificate to prevent these attacks and to find the malicious node. These attacks are simulated using NS2.28 version and the proposed proactive technique is implemented. The following metrics like packet delivery ratio, control overhead, total overhead and End to End delay are used to prove that the proposed solution is secure and robust.

    2010-11-01

    A Mobile Ad Hoc Network (MANET) is a temporary network set up by a wireless mobile computers moving arbitrary in the places that have no network infrastructure. These nodes maintain connectivity in a decentralized manner. Since the nodes communicate with each other, they cooperate by forwarding data packets to other nodes in the network. Thus the nodes find a path to the destination node using routing protocols. However, due to security vulnerabilities of the routing protocols, mobile ad-hoc networks are unprotected to attacks of the malicious nodes. One of these attacks is the Black Hole Attack against network integrity absorbing all data packets in the network. Since the data packets do not reach the destination node on account of this attack, data loss will occur. In this paper, we simulated the black hole attack in various mobile ad-hoc network scenarios using AODV routing protocol of MANET and have tried to find a effect if number of nodes are increased with increase in malicious nodes.

    Full Text Available In order to increase employee productivity within a feasible budget, we have to track newtechnologies, investigate and choose the best plan and implementation of these technologies.WLAN is vulnerable to malicious attacks due to their shared medium in unlicensed frequencyspectrum, thus requiring security features for a variety of applications.This paper will discuss some techniques and approaches which can help to detect, localize andidentify wireless network attacks, which present a unique set of challenges to IT and securityprofessionals. All efforts were focusing on the ability to identity based attacks in which amalicious device uses forged MAC addresses to masquerade as a specific client or to createmultiple illegitimate identities. Also, to be sure that the network is able to robustly identify eachtransmitter independently of packet contents, allowing detection of a large class of identity-basedattacks with high probability.The attacker can listen to all wireless traffic, compromise encryption and Use attenuators,amplifiers, directional antennas, software radios, but he cannot be at the location of user or at thelocation of access points. However, we have to choose the best design, implementation, andevaluation techniques in order to secure our network from attackers, where our choice willdepend on a technical implementation to mitigate the risk on the enterprise network infrastructure.

    2006-05-01

    The pervasiveness of software and networked information systems is evident across a broad spectrum of business and government sectors. Such reliance provides an ample opportunity not only for the nefarious exploits of lone wolf computer hackers, but for more systematic software attacks from organized entities. Much effort and focus has been placed on preventing and ameliorating network and OS attacks, a concomitant emphasis is required to address protection of mission critical software. Typical software protection technique and methodology evaluation and verification and validation (V&V) involves the use of a team of subject matter experts (SMEs) to mimic potential attackers or hackers. This manpower intensive, time-consuming, and potentially cost-prohibitive approach is not amenable to performing the necessary multiple non-subjective analyses required to support quantifying software protection levels. To facilitate the evaluation and V&V of software protection solutions, we have designed and developed a prototype adaptive cyber attack modeling system. Our approach integrates an off-line mechanism for rapid construction of Bayesian belief network (BN) attack models with an on-line model instantiation, adaptation and knowledge acquisition scheme. Off-line model construction is supported via a knowledge elicitation approach for identifying key domain requirements and a process for translating these requirements into a library of BN-based cyber-attack models. On-line attack modeling and knowledge acquisition is supported via BN evidence propagation and model parameter learning.

    As technology continues to advance, services and capabilities become computerized, and an ever increasing amount of business is conducted electronically the threat of cyber attacks gets compounded by the complexity of such attacks and the criticality of the information which must be secured. A new age of virtual warfare has dawned in which seconds can differentiate between the protection of vital information and/or services and a malicious attacker attaining their goal. In this paper we present a novel approach in the real-time detection of multistage coordinated cyber attacks and the promising initial testing results we have obtained. We introduce INFERD (INformation Fusion Engine for Real-time Decision-making), an adaptable information fusion engine which performs fusion at levels zero, one, and two to provide real-time situational assessment and its application to the cyber domain in the ECCARS (Event Correlation for Cyber Attack Recognition System) system. The advantages to our approach are fourfold: (1) The complexity of the attacks which we consider, (2) the level of abstraction in which the analyst interacts with the attack scenarios, (3) the speed at which the information fusion is presented and performed, and (4) our disregard for ad-hoc rules or a priori parameters.

    Full Text Available Wireless ad hoc network is a collection of wireless mobile nodes that dynamically self-organize in arbitrary and temporary network topologies. As compared to conventional network, wireless ad hocnetwork are more vulnerable to the security attacks. The nature and structure of wireless ad hoc network makes it very attractive to attackers, because there is no fixed infrastructure and administrativeapproach in it. “Sinkhole attack” is one of the severe attacks in this type of network; this makes trustable nodes to malicious nodes that result in loss of secure information. This paper focuses on sinkhole attacks on routing protocols such as DSR, AODV. To overcome the problems occur due to sinkhole we discuss about Security-aware routing (SAR which helps to reduce the impact of such attack.

    Teixeira, André; Sandberg, Henrik; Johansson, Karl H

    2010-01-01

    The electrical power network is a critical infrastructure in today's society, so its safe and reliable operation is of major concern. State estimators are commonly used in power networks, for example, to detect faulty equipment and to optimally route power flows. The estimators are often located in control centers, to which large numbers of measurements are sent over unencrypted communication channels. Therefore cyber security for state estimators becomes an important issue. In this paper we analyze the cyber security of state estimators in supervisory control and data acquisition (SCADA) for energy management systems (EMS) operating the power network. Current EMS state estimation algorithms have bad data detection (BDD) schemes to detect outliers in the measurement data. Such schemes are based on high measurement redundancy.

    Full Text Available The panic-respiration connection has been presented with increasing evidences in the literature. We report three panic disorder patients with nocturnal panic attacks with prominent respiratory symptoms, the overlapping of the symptoms with the sleep apnea syndrome and a change of the diurnal panic attacks, from spontaneous to situational pattern. The implication of these findings and awareness to the distinct core of the nocturnal panic attacks symptoms may help to differentiate them from sleep disorders and the search for specific treatment.

    2014-03-01

    Full Text Available A Mobile Ad Hoc Network (MANET is a self organizing, infrastructure less, multi-hop network. The wireless and distributed nature of MANETs poses a great challenge to system security designers. Ad hoc networks are by nature very open to anyone. Anyone with the proper hardware and knowledge of the network topology and protocols can connect to the network. This allows potential attackers to infiltrate the network and carry out attacks on its participants with the purpose of stealing or altering information. A specific type of attack, the Wormhole attack does not require exploiting any nodes in the network and can interfere with the route establishment process. It does not require any cryptographic primitives. This attack targets specifically routing control packets, the nodes that are close to the attackers are shielded from any alternative routes with more than one or two hops to the remote location. All routes are thus directed to the wormhole established by the attackers. The entire routing system in MANET can even be brought down using the wormhole attack. We have presented several existing techniques to detect wormhole attack in mobile ad hoc networks.

    Full Text Available The ad-hoc networks are the temporarily established wireless networks which does not require fixedinfrastructure it is also called as infrastructure less network. Because of some flaws of adhoc networksuch as shared wireless medium and lack of any central coordination makes them more prone to attacksin comparison with the wired network. Among all the attacks wormhole attack is the most severe attack.In this attack an attacker capture the packets at one location in the network and send it two anotherattacker at a distant location through tunnels which is established through different ways like packetencapsulation, using high power transmission or by using direct antennas. This tunnel between twocolluding attackers is virtual and it is called as a wormhole. The wormhole attack is possible even if theattacker has not comprised any hosts, and all communication provides authenticity and confidentiality.By using the various approaches for finding the solution over wormhole attack, the dynamic informationof the packets could still be modified. So in order to give more robust protection in some special scenariolike battlefields, which requires highly secured information, there is need of developing some securedmechanism for wormhole detection and prevention. Taking into consideration this problem the proposedscheme is developed. This paper discusses proposed works on wormhole attack along with its availablecounter measures in ad-hoc wireless network.

    A successful attack strategy in neural cryptography is presented. The neural cryptosystem, based on synchronization of neural networks by mutual learning, has been recently shown to be secure under different attack strategies. The success of the advanced attacker presented here, called the "majority-flipping attacker," does not decay with the parameters of the model. This attacker's outstanding success is due to its using a group of attackers which cooperate throughout the synchronization process, unlike any other attack strategy known. An analytical description of this attack is also presented, and fits the results of simulations.

    Using a recently introduced network model with node and connection diversity, we study the breakdown of different scale-free networks under intentional attacks. Our simulation results show that inhomogeneous networks are more sensitive to intentional attack than the homogeneous ones and that the centralization of the networks is an important variable, reflecting the characteristics of the network under intentional attack. Using a recently introduced method we can theoretically develop the critical point of the inhomogeneous networks.

    Terrorist attacks on transportation networks have traumatized modern societies. With a single blast, it has become possible to paralyze airline traffic, electric power supply, ground transportation or Internet communication. How and at which cost can one restructure the network such that it will become more robust against a malicious attack? We introduce a unique measure for robustness and use it to devise a method to mitigate economically and efficiently this risk. We demonstrate its efficiency on the European electricity system and on the Internet as well as on complex networks models. We show that with small changes in the network structure (low cost) the robustness of diverse networks can be improved dramatically while their functionality remains unchanged. Our results are useful not only for improving significantly with low cost the robustness of existing infrastructures but also for designing economically robust network systems.

    2014-01-01

    Full Text Available A Mobile Ad-Hoc Network (MANET is a self configuring, infrastructure less network of mobile devices connected by wireless links. Loopholes like wireless medium, lack of a fixed infrastructure, dynamic topology, rapid deployment practices, and the hostile environments in which they may be deployed, make MANET vulnerable to a wide range of security attacks and Wormhole attack is one of them. During this attack a malicious node captures packets from one location in the network, and tunnels them to another colluding malicious node at a distant point, which replays them locally. This paper presents a cluster based Wormhole attack avoidance technique. The concept of hierarchical clustering with a novel hierarchical 32- bit node addressing scheme is used for avoiding the attacking path during the route discovery phase of the DSR protocol, which is considered as the under lying routing protocol. Pinpointing the location of the wormhole nodes in the case of exposed attack is also given by using this method.

    Full Text Available A mobile ad-hoc network (MANET consists of mobile hosts equipped with wireless communication devices. A Mobile Ad hoc Network is a self-organizing, infrastructure less, multi-hop network. The transmission of a mobile host is received by all hosts within its transmission range due to the broadcast nature of wireless communication and unidirectional antenna. If two wireless hosts are out of their transmission ranges in the ad hoc networks, other mobile hosts located between them can forward their message, which effectively builds connected networks among the mobile hosts in the deployed area. One main challenge in design of these networks is their vulnerable nature to security attack. These attacks can be deployed by insider or outsider attacker. Sometime, the node from network can be attacker. This is happen because of mobility of nodes and changing network topology. There are different kind of attacks available in literature and can be implemented on MANET. One of these attacks is Grey Hole attack that has dangerous effect on Mobile Ad-Hoc Network. In this paper, we study the effect of Grey Hole attack on Dynamic Source Routing (DSR protocol in Mobile Ad-Hoc Network.

    2009-10-01

    This report documents the architecture and implementation of a Parallel Digital Forensics infrastructure. This infrastructure is necessary for supporting the design, implementation, and testing of new classes of parallel digital forensics tools. Digital Forensics has become extremely difficult with data sets of one terabyte and larger. The only way to overcome the processing time of these large sets is to identify and develop new parallel algorithms for performing the analysis. To support algorithm research, a flexible base infrastructure is required. A candidate architecture for this base infrastructure was designed, instantiated, and tested by this project, in collaboration with New Mexico Tech. Previous infrastructures were not designed and built specifically for the development and testing of parallel algorithms. With the size of forensics data sets only expected to increase significantly, this type of infrastructure support is necessary for continued research in parallel digital forensics. This report documents the implementation of the parallel digital forensics (PDF) infrastructure architecture and implementation.

    2013-01-01

    Compromises attributable to the Advanced Persistent Threat (APT) highlight the necessity for constant vigilance. The APT provides a new perspective on security metrics (e.g., statistics based cyber security) and quantitative risk assessments. We consider design principals and models/tools that provide high assurance for energy delivery systems (EDS) operations regardless of the state of compromise. Cryptographic keys must be securely exchanged, then held and protected on either end of a communications link. This is challenging for a utility with numerous substations that must secure the intelligent electronic devices (IEDs) that may comprise complex control system of systems. For example, distribution and management of keys among the millions of intelligent meters within the Advanced Metering Infrastructure (AMI) is being implemented as part of the National Smart Grid initiative. Without a means for a secure cryptographic key management system (CKMS) no cryptographic solution can be widely deployed to protect the EDS infrastructure from cyber-attack. We consider 1) how security modeling is applied to key management and cyber security concerns on a continuous basis from design through operation, 2) how trusted models and key management architectures greatly impact failure scenarios, and 3) how hardware-enabled trust is a critical element to detecting, surviving, and recovering from attack.

  5. Improving the Resilience of Major Ports and Critical Supply Chains to Extreme Coastal Flooding: a Combined Artificial Neural Network and Hydrodynamic Simulation Approach to Predicting Tidal Surge Inundation of Port Infrastructure and Impact on Operations.

    French, J.

    2015-12-01

    Ports are vital to the global economy, but assessments of global exposure to flood risk have generally focused on major concentrations of population or asset values. Few studies have examined the impact of extreme inundation events on port operation and critical supply chains. Extreme water levels and recurrence intervals have conventionally been estimated via analysis of historic water level maxima, and these vary widely depending on the statistical assumptions made. This information is supplemented by near-term forecasts from operational surge-tide models, which give continuous water levels but at considerable computational cost. As part of a NERC Infrastructure and Risk project, we have investigated the impact of North Sea tidal surges on the Port of Immingham, eastern, UK. This handles the largest volume of bulk cargo in the UK and flows of coal and biomass that are critically important for national energy security. The port was partly flooded during a major tidal surge in 2013. This event highlighted the need for improved local forecasts of surge timing in relation to high water, with a better indication of flood depth and duration. We address this problem using a combination of data-driven and numerical hydrodynamic models. An Artificial Neural Network (ANN) is first used to predict the surge component of water level from meteorological data. The input vector comprises time-series of local wind (easterly and northerly wind stress) and pressure, as well as regional pressure and pressure gradients from stations between the Shetland Islands and the Humber estuary. The ANN achieves rms errors of around 0.1 m and can generate short-range (~ 3 to 12 hour) forecasts given real-time input data feeds. It can also synthesize water level events for a wider range of tidal and meteorological forcing combinations than contained in the observational records. These are used to force Telemac2D numerical floodplain simulations using a LiDAR digital elevation model of the port

    1997-12-31

    A major part of technological advancement has involved the development of complex infrastructure systems, including electric power generation, transmission, and distribution networks; oil and gas pipeline systems; highway and rail networks; and telecommunication networks. Dependence on these infrastructure systems renders them attractive targets for conflict in the twenty-first century. Hostile governments, domestic and international terrorists, criminals, and mentally distressed individuals will inevitably find some part of the infrastructure an easy target for theft, for making political statements, for disruption of strategic activities, or for making a nuisance. The current situation regarding the vulnerability of the infrastructure can be summarized in three major points: (1) our dependence on technology has made our infrastructure more important and vital to our everyday lives, this in turn, makes us much more vulnerable to disruption in any infrastructure system; (2) technologies available for attacking infrastructure systems have changed substantially and have become much easier to obtain and use, easy accessibility to information on how to disrupt or destroy various infrastructure components means that almost anyone can be involved in this destructive process; (3) technologies for defending infrastructure systems and preventing damage have not kept pace with the capability for destroying such systems. A brief review of these points will illustrate the significance of infrastructure and the growing dangers to its various elements.

We show both analytically and numerically, how the coupling strength and clustering coefficient effect the percolation threshold, size of giant component, critical coupling point where the behavior of phase transition changes from second order to first order with the increase of coupling strength between the networks. Last, we study the two types of clustering network: one type is same with double clustering network in which each subnetwork satisfies ...

    numbers they want (several millions per year). The crossover point where building a dedicated facility becomes a realistic option, can differ very much depending on technology complexity, numbers and market value. Also history plays a role, companies with past experience in the production of a product and the necessary facilities and equipment will tend to achieve captive production. Companies not having a microtechnology history will tend to outsource, offering business opportunities for foundries. The number of foundries shows a steady growth over the years. The total availability of foundries, however, and their flexibility will, undoubtedly, rely on market potential and its size. Unlike design houses, foundries need to realise a substantial return on the "large" investments they make in terms of capital and infrastructure. These returns will be maximised through mass-produced products aimed at "killer" applications (accelerometers are only one example). The existence of professional suppliers of MOEMS packaging and assembly is an essential element in the supply chain and critical for the manufacturing and commercialisation of MOEMS products. In addition, the incorporation of packaging and assembly techniques at the front-end of the engineering cycle will pay back in terms of financial savings and shorter timescales to market. Packaging and assembly for MOEMS are, in general, more costly than their equivalents for standard integrated circuits. This is, primarily, due to the diversity of the interconnections (which are multi-functional and may incorporate: electrical, optical, fluidic etc). In addition, the high levels of accuracy and the potential sensitivity of the devices to mechanical and external influences play a major role in the cost aspects of the final MNT product. This article will give an overview of the package/assembly providers and foundry business models and analyse their contribution to the MOEMS supply chain illustrated with some typical examples. As

    Full Text Available In this paper, we discuss the methods for detecting and preventing the DDoS Attacks and Replay Attacks, which have been posing the problems for the Internet. We explained a scheme AMFDR (AttackPatterns for Marking Filtering DoS and Replay attacks that identifies the attack packets from the packets that are sent by legitimate users and filters the attack packets. A Denial of service attack is generally launched to make a service unavailable even to an unauthorized user. If this attack uses many computers across the world, it is called Distributed Denial of service attack. Replay attack is retransmission of a data transmission which used to gain authentication in a fraudulent manner. These replayed packets or attack packets are identified. This scheme is less expensive and the implementation of this scheme needs minimal interaction with routers. The scheme is like firewall system, so that the occurrence of an attack is recognized quickly and a punitive action is taken without any loss genuine packets.

    Full Text Available While terror attacks that are a part of a coordinated effort receive attention in the popular media, they have not received much attention in the academic literature. The decision to carry out simultaneous attacks should be examined as one of the choices a terrorist organisation makes about the method of attack. Determining the impact of simultaneous attacks vis-à-vis a single attack can explain why groups would use this method. Up to one quarter of all attacks coded in two major databases, GTD and ITERATE, may be part of a simultaneous campaign. Empirical analysis shows simultaneous attacks are more likely to be successful and cause more fatalities, though not in a one-to-one fashion. These results underline the importance of considering simultaneous attacks in empirical analysis.

    Mobile ad hoc networks (MANETs) are dynamic wireless networks without any infrastructure. These networks are weak against many types of attacks. One of these attacks is the black hole. In this attack, a malicious node advertises itself as having freshest or shortest path to specific node to absorb packets to itself. The effect of black hole attack on ad hoc network using AODV as a routing protocol will be examined in this research. Furthermore, we investigate solution for increasing security in these networks. Simulation results using OPNET simulator depict that packet delivery ratio in the presence of malicious nodes, reduces notably.

    The common assumption that female candidates on the campaign trail should not go on the attack, because such tactics contradict gender stereotypes, has not received consistent support. We argue that in some circumstances gender stereotypes will favor female politicians going negative. To test this proposition, this study examines how gender cues affect voter reactions to negative ads in the context of a political sex scandal, a context that should prime gender stereotypes that favor females. Using an online experiment involving a national sample of U.S. adults (N = 599), we manipulate the gender and partisan affiliation of a politician who attacks a male opponent caught in a sex scandal involving sexually suggestive texting to a female intern. Results show that in the context of a sex scandal, a female candidate going on the attack is evaluated more positively than a male. Moreover, while female participants viewed the female sponsor more favorably, sponsor gender had no effect on male participants. Partisanship also influenced candidate evaluations: the Democratic female candidate was evaluated more favorably than her Republican female counterpart. PMID:26399945

    Full Text Available To cope up the network security measures with the financial restrictions in the corporate world is still a challenge. At global scenario the tradeoff between the protection of IT infrastructure and the financial boundation for any organization using IT as valuable resource is quite essential. Every organization has different security needs and different budgets for coping with that therefore whether it has to look as single objective or as multiple objectives with fault tolerant feature is a critical issue. In the present paper an attempt has been taken to optimize and analyze the effectiveness of security hardening measures considering attack tree model as base. In short we can say that the main attention in the paper is-to rectify, to describe the notations of the attack tree model and to suggest a model which may be able to quantitatively specify the possible threats as well as cost of the security control while implementing the security hardening measures.

    Full Text Available In the present era Internet has changed the way of traditional essential services such as banking, transportation, power, health, and defence being operated. These operations are being replacedby cheaper, more efficient Internet-based applications. It is all because of rapid growth and success of Internet in every sector. Unfortunately with the growth of Internet, count of attacks on Internet has also increased incredibly fast. Denial-of-service attack is one of them, which poses immense threat on the availability. Since, the World is highly dependent on the Internet, availability of the Internet is very critical for the socio-economic growth of the society. Denial-of-service attacks occur almost every day,and the frequency and the volume of these attacks are increasing day by day. One of the biggest challenges before researchers is to find the details of such attacks because due to damaging reputationissues, most of the commercial sites do not even disclose that they were blitzed by such attacks. Details of attacks can guide very well in the formulation of comprehensive defensive solution for such attacks. In this paper, an overview on DDoS problem, major factors causing DDoS attacks are demonstrated, brief detail of most recent DDoS incidents on online organizations is outlined and finally, the need for a comprehensive distributed solution is highlighted.

    Full Text Available Web applications suffer from cross-site scripting (XSS attacks that resulting from incomplete or incorrect input sanitization. Learning the structure of attack vectors could enrich the variety of manifestations in generated XSS attacks. In this study, we focus on generating more threatening XSS attacks for the state-of-the-art detection approaches that can find potential XSS vulnerabilities in Web applications, and propose a mechanism for structural learning of attack vectors with the aim of generating mutated XSS attacks in a fully automatic way. Mutated XSS attack generation depends on the analysis of attack vectors and the structural learning mechanism. For the kernel of the learning mechanism, we use a Hidden Markov model (HMM as the structure of the attack vector model to capture the implicit manner of the attack vector, and this manner is benefited from the syntax meanings that are labeled by the proposed tokenizing mechanism. Bayes theorem is used to determine the number of hidden states in the model for generalizing the structure model. The paper has the contributions as following: (1 automatically learn the structure of attack vectors from practical data analysis to modeling a structure model of attack vectors, (2 mimic the manners and the elements of attack vectors to extend the ability of testing tool for identifying XSS vulnerabilities, (3 be helpful to verify the flaws of blacklist sanitization procedures of Web applications. We evaluated the proposed mechanism by Burp Intruder with a dataset collected from public XSS archives. The results show that mutated XSS attack generation can identify potential vulnerabilities.

  3. A Study of Direct and Indirect Costs Resulting from a Radiological Attack by Terrorists

    International Nuclear Information System (INIS)

    An uncontrolled release of radioactivity caused by a terrorist attack is expected to result in an - incident of national significance - and have the potential consequence of a significant economic impact. The magnitude of the economic impact and the range of impacted entities are somewhat controversial. This paper will discuss the elements and methodology that comprise the buildup of an estimate for a specific critical infrastructure. The radiological attack event was studied by the Department of Homeland Security (DHS) to estimate the health and economic impacts of a radionuclide attack. The cost estimate was based on response actions outlined in the DHS National Response Plan and the Environmental Protection Agency (EPA) Response Protocol Toolbox: Planning for and Responding to Drinking Water Contamination Threats and Incidents. A response plan was developed to support the options for the estimate. Several response and cleanup options were evaluated to determine a range of potential costs. It is the breakdown of the cost elements and their relative size that is discussed in this paper. The first step in the estimating process was the development of the terrorist attack characteristics that were to be estimated. Example response timelines were developed to determine what immediate operational response actions are possible to mitigate the attack consequences. Based on the attack assumptions, costs were estimated for a number of response and remediation options that may be employed. Finally, each parameter was evaluated to account for the range of values possible and its effect on the total cost. Cost estimates were based on data from standard references, internet searches on specific subjects, and information from recent terrorist activities. These costs were broken down into Micro-economic Level Costs (primarily associated with Medical Treatment, Remediation, and Business Interruption) and Macroeconomic Level Costs (primarily associated with the value of life lost

  6. Improving Attack Graph Visualization through Data Reduction and Attack Grouping

    John Homer; Ashok Varikuti; Xinming Ou; Miles A. McQueen

    2008-09-01

    Various tools exist to analyze enterprise network systems and to produce attack graphs detailing how attackers might penetrate into the system. These attack graphs, however, are often complex and difficult to comprehend fully, and a human user may find it problematic to reach appropriate configuration decisions. This paper presents methodologies that can 1) automatically identify portions of an attack graph that do not help a user to understand the core security problems and so can be trimmed, and 2) automatically group similar attack steps as virtual nodes in a model of the network topology, to immediately increase the understandability of the data. We believe both methods are important steps toward improving visualization of attack graphs to make them more useful in configuration management for large enterprise networks. We implemented our methods using one of the existing attack-graph toolkits. Initial experimentation shows that the proposed approaches can 1) significantly reduce the complexity of attack graphs by trimming a large portion of the graph that is not needed for a user to understand the security problem, and 2) significantly increase the accessibility and understandability of the data presented in the attack graph by clearly showing, within a generated visualization of the network topology, the number and type of potential attacks to which each host is exposed.

    The information technology infrastructure of an organization, whether it is a private, non-profit, federal, or academic institution, is key to delivering timely and high-quality products and services to its customers and stakeholders. With the evolution of the Internet and the World Wide Web, resources that were once "centralized" in nature are now distributed across the organization in various locations and often remote regions of the country. This presents tremendous challenges to the information technology managers, users, and CEOs of large world-wide corporations who wish to exchange information or get access to resources in today's global marketplace. Several tools and technologies have been developed over recent years that play critical roles in ensuring that the proper information infrastructure exists within the organization to facilitate this global information marketplace Such tools and technologies as JAVA, Proxy Servers, Virtual Private Networks (VPN), multi-platform database management solutions, high-speed telecommunication technologies (ATM, ISDN, etc.), mass storage devices, and firewall technologies most often determine the organization's success through effective and efficient information infrastructure practices. This session will address several of these technologies and provide options related to those that may exist and can be readily applied within Eastern Europe. ?? 2004 - IOS Press and the authors.

    McLaughlin, Stephen; Podkuiko, Dmitry; McDaniel, Patrick

    Global energy generation and delivery systems are transitioning to a new computerized "smart grid". One of the principle components of the smart grid is an advanced metering infrastructure (AMI). AMI replaces the analog meters with computerized systems that report usage over digital communication interfaces, e.g., phone lines. However, with this infrastructure comes new risk. In this paper, we consider adversary means of defrauding the electrical grid by manipulating AMI systems. We document the methods adversaries will use to attempt to manipulate energy usage data, and validate the viability of these attacks by performing penetration testing on commodity devices. Through these activities, we demonstrate that not only is theft still possible in AMI systems, but that current AMI devices introduce a myriad of new vectors for achieving it.

  13. Security Challenges and Attacks in Mobile Ad Hoc Networks

    Directory of Open Access Journals (Sweden)

    CH.V. Raghavendran

    2013-09-01

    Full Text Available Mobile Ad hoc Network (MANET is an autonomous collection of mobile nodes that form a temporary network without of any existing network infrastructure or central access point. The popularity of these networks created security challenges as an important issue. The traditional routing protocols perform well with dynamically changing topology but are not designed to defense against security challenges. In this paper we discuss about current challenges in an ad hoc environment which includes the different types of potential attacks that are possible in the Mobile Ad hoc Networks that can harm its working and operation. We have done literature study and gathered information relating to various types of attacks. In our study, we have found that there is no general algorithm that suits well against the most commonly known attacks. But the complete security solution requires the prevention, detection and reaction mechanisms applied in MANET. To develop suitable security solutions for such environments, we must first understand how MANETs can be attacked. This paper provides a comprehensive study of attacks against mobile ad hoc networks. We present a detailed classification of the attacks against MANETs.

    2012-05-14

    Supervisory Control and Data Acquisition (SCADA) Systems are a type of Industrial Control System characterized by the centralized (or hierarchical) monitoring and control of geographically dispersed assets. SCADA systems combine acquisition and network components to provide data gathering, transmission, and visualization for centralized monitoring and control. However these integrated capabilities, especially when built over legacy systems and protocols, generally result in vulnerabilities that can be exploited by attackers, with potentially disastrous consequences. Our research project proposal was to investigate new approaches for secure and survivable SCADA systems. In particular, we were interested in the resilience and adaptability of large-scale mission-critical monitoring and control infrastructures. Our research proposal was divided in two main tasks. The first task was centered on the design and investigation of algorithms for survivable SCADA systems and a prototype framework demonstration. The second task was centered on the characterization and demonstration of the proposed approach in illustrative scenarios (simulated or emulated).

    2009-03-20

    Lawrence Livermore National Laboratory (LLNL) is working with the Department of Homeland Security's Science and Technology Directorate, the Transportation Security Administration, and several infrastructure partners to characterize and help mitigate principal structural vulnerabilities to explosive threats. Given the importance of infrastructure to the nation's security and economy, there is a clear need for applied research and analyses (1) to improve understanding of the vulnerabilities of these systems to explosive threats and (2) to provide decision makers with time-critical technical assistance concerning countermeasure and mitigation options. Fully-coupled high performance calculations of structural response to ideal and non-ideal explosives help bound and quantify specific critical vulnerabilities, and help identify possible corrective schemes. Experimental validation of modeling approaches and methodologies builds confidence in the prediction, while advanced stochastic techniques allow for optimal use of scarce computational resources to efficiently provide infrastructure owners and decision makers with timely analyses.

  19. Impact of Rushing attack on Multicast in Mobile Ad Hoc Network

    CERN Document Server

    Palanisamy, V

    2009-01-01

    A mobile ad hoc network (MANETs) is a self-organizing system of mobile nodes that communicate with each other via wireless links with no fixed infrastructure or centralized administration such as base station or access points. Nodes in a MANETs operate both as host as well as routers to forward packets for each other in a multihop fashion. For many applications in wireless networks, multicasting is an important and frequent communication service. By multicasting, since a single message can be delivered to multiple receivers simultaneously. It greatly reduces the transmission cost when sending the same packet to multiple recipients. The security issue of MANETs in group communications is even more challenging because of involvement of multiple senders and multiple receivers. At that time of multicasting, mobile ad hoc network are unprotected by the attacks of malicious nodes because of vulnerabilities of routing protocols. Some of the attacks are Rushing attack, Blackhole attack, Sybil attack, Neighbor attack ...

    Full Text Available WSNs are vulnerable to attacks and have deemed special attention for developing mechanism for securing against various threats that could effect the overall infrastructure. WSNs are open to miscellaneous classes of attacks and security breaches are intolerable in WSNs. Threats like untrusted data transmissions, settlement in open and unfavorable environments are still open research issues. Safekeeping is an essential and complex requirement in WSNs. These issues raise the need to develop a security-based mechanism for Wireless Sensor Network to categorize the different attacks based on their relevance. A detailed survey of active attacks is highlighted based on the nature and attributes of those attacks. An Ontology based mechanism is developed and tested for active attack in WSNs.

    Full Text Available A Mobile Ad hoc NETwork (MANETs is a continuously changing wireless network that can be created without any pre-existing infrastructure in which each node can operate as a router. MANETs has no clear line of control, so it is accessible to both legitimate network users and malicious attackers. The main challenge in MANETs is to design a secure solution which can protect the MANET from various kinds of security attacks.In this paper, we put a first step towards securing multicast routing protocol for ad hoc network. Specifically we examine the vulnerabilities of PUMA (Protocol for Unified Multicasting through Announcements which is a representative of mesh based routing protocol. In this proposed work, we have presented a trust based approach where in which the secure route is selected for the receivers not only based on current trust values of its neighbor nodes but also its past experience is considered for blackhole and wormhole attack

    For many years CERN had a very sophisticated print server infrastructure [13] which supported several different protocols (AppleTalk, IPX and TCP/IP) and many different printing standards. Today's situation differs a lot: we have a much more homogenous network infrastructure, where TCP/IP is used everywhere and we have less printer models, which almost all work using current standards (i.e. they all provide PostScript drivers). This change gave us the possibility to review the printing architecture aiming at simplifying the infrastructure in order to achieve full automation of the service. The new infrastructure offers both: LPD service exposing print queues to Linux and Mac OS X computers and native printing for Windows based clients. The printer driver distribution is automatic and native on Windows and automated by custom mechanisms on Linux, where the appropriate Foomatic drivers are configured. Also the process of printer registration and queue creation is completely automated following the printer regis...

    2010-06-01

    Panic attacks are sudden debilitating attacks of intense distress often accompanied by physical symptoms such as shortness of breath and heart palpitations. Numerous brain regions, hormones, and neurotransmitter systems are putatively involved, but the etiology and neurocircuitry of panic attacks is far from established. One particular brain region of interest is the ventromedial hypothalamus (VMH). In cats and rats, electrical stimulation delivered to the VMH has been shown to evoke an emotional "panic attack-like" escape behavior, and in humans, stimulation targeting nuclei just posterior or anterior to the VMH has reportedly induced panic attacks. The authors report findings obtained in an awake patient undergoing bilateral implantation of deep brain stimulation electrodes into the hypothalamus that strongly implicates the VMH as being critically involved in the genesis of panic attacks. First, as the stimulating electrode progressed deeper into the VMH, the intensity of stimulation required to evoke an attack systematically decreased; second, while stimulation of the VMH in either hemisphere evoked panic, stimulation that appeared to be in the center of the VMH was more potent. Thus, this evidence supports the role of the VMH in the induction of panic attacks purported by animal studies. PMID:19852539

    I use a simple optimal stopping model to derive policy relevant insights on the timing of one-shot attacks by small autonomous terrorist units or “lone wolf” individuals. A main insight is that an increase in proactive counterterrorism measures can lead to a short term increase in the number...... of attempted terrorist attacks because it makes it more risky for existing terrorist units to pursue further development of capabilities. This is consistent with the events in London in 2005 where a terrorist attack on 7 July was followed by a similar but unsuccessful attack two weeks later....

    Full Text Available New infrastructures, new landscapes AbstractThe paper will discuss one recent Italian project that share a common background: the relevance of the existing maritime landscape as a non negotiable value. The studies will be discussed in details a feasibility study for the new port in Monfalcone. National infrastructural policies emphasize competitiveness and connection as a central issue incultural, economic and political development of communities . Based on networks and system development along passageways that make up the European infrastructural armor; the two are considered at the meantime as cause and effect of "territorialisation”. These two views are obviously mutually dependent. It's hard to think about a strong attractiveness out of the network, and to be part of the latter encourages competitiveness. Nonetheless this has proved to be conflictual when landscape values and the related attractiveness are considered.The presented case study project, is pursuing the ambition to promote a new approach in realizing large infrastructures; its double role is to improve connectivity and to generate lasting and positive impact on the local regions. It deal with issues of inter-modality and the construction of nodes and lines which connects Europe, and its markets.Reverting the usual approach which consider landscape project as as a way to mitigate or to compensate for the infrastructure, the goal is to succeed in realizing large infrastructural works by conceiving them as an occasion to reinterpret a region or, as extraordinary opportunities, to build new landscapes.The strategy proposed consists in achieving structural images based on the reinforcement of the environmental and historical-landscape systems. Starting from the reinterpretation of local maritime context and resources it is possible not just to preserve the attractiveness of a specific landscape but also to conceive infrastructure in a more efficient way.

    This report summarizes work fimded jointly by the U.S. Department of Energy (DOE) and by the Gas Research Institute (GRI) to (1) identi& barriers to establishing sustainable natural gas vehicle (NGV) infrastructure and (2) develop planning information that can help to promote a NGV infrastructure with self-sustaining critical maw. The need for this work is driven by the realization that demand for NGVS has not yet developed to a level that provides sufficient incentives for investment by the commercial sector in all necessary elements of a supportive infrastructure. The two major objectives of this project were: (1) to identifi and prioritize the technical barriers that may be impeding growth of a national NGV infrastructure and (2) to develop input that can assist industry in overcoming these barriers. The approach used in this project incorporated and built upon the accumulated insights of the NGV industry. The project was conducted in three basic phases: (1) review of the current situation, (2) prioritization of technical infrastructure btiiers, and (3) development of plans to overcome key barriers. An extensive and diverse list of barriers was obtained from direct meetings and telephone conferences with sixteen industry NGV leaders and seven Clean Cities/Clean Corridors coordinators. This information is filly documented in the appendix. A distillation of insights gained in the interview process suggests that persistent barriers to developing an NGV market and supporting infrastructure can be grouped into four major categories: 1. Fuel station economics 2. Value of NGVs from the owner/operator perspective 3. Cooperation necessary for critical mass 4. Commitment by investors. A principal conclusion is that an efficient and effective approach for overcoming technical barriers to developing an NGV infrastructure can be provided by building upon and consolidating the relevant efforts of the NGV industry and government. The major recommendation of this project is the

    Full Text Available The scope of the paper is to overview the different approaches for evaluation of urban infrastructure sustainability. In this context, urban infrastructure covers transportation, energy, water, sewage and information networks as well as waste management and blue-green infrastructure, in terms of both the supply and demand side. A common effort of partners in the European project “C8—Best Practice in Sustainable Urban Infrastructure”, developed under the Cooperation in Science and Technology program (COST, in brief COST C8, was focused on defining the methods, indicators and criteria for evaluation of sustainability, and resulted in a guidebook for decision-makers in local authorities. Here, the COST C8 matrix for simple sustainability assessment of urban infrastructure is applied to The Path (POT case—a circular memorial and recreational park around the city of Ljubljana, Slovenia. The applicability and acceptance of the matrix in 43 other cases of sustainable urban infrastructure, collected in the COST C8 project, is presented and discussed.

  16. Metrics for Assessment of Smart Grid Data Integrity Attacks

    There is an emerging consensus that the nation’s electricity grid is vulnerable to cyber attacks. This vulnerability arises from the increasing reliance on using remote measurements, transmitting them over legacy data networks to system operators who make critical decisions based on available data. Data integrity attacks are a class of cyber attacks that involve a compromise of information that is processed by the grid operator. This information can include meter readings of injected power at remote generators, power flows on transmission lines, and relay states. These data integrity attacks have consequences only when the system operator responds to compromised data by redispatching generation under normal or contingency protocols. These consequences include (a) financial losses from sub-optimal economic dispatch to service loads, (b) robustness/resiliency losses from placing the grid at operating points that are at greater risk from contingencies, and (c) systemic losses resulting from cascading failures induced by poor operational choices. This paper is focused on understanding the connections between grid operational procedures and cyber attacks. We first offer two examples to illustrate how data integrity attacks can cause economic and physical damage by misleading operators into taking inappropriate decisions. We then focus on unobservable data integrity attacks involving power meter data. These are coordinated attacks where the compromised data are consistent with the physics of power flow, and are therefore passed by any bad data detection algorithm. We develop metrics to assess the economic impact of these attacks under re-dispatch decisions using optimal power flow methods. These metrics can be use to prioritize the adoption of appropriate countermeasures including PMU placement, encryption, hardware upgrades, and advance attack detection algorithms.

    Attacks on classical cryptographic protocols are usually modeled by allowing an adversary to ask queries from an oracle. Security is then defined by requiring that as long as the queries satisfy some constraint, there is some problem the adversary cannot solve, such as compute a certain piece...... string model. While our protocol is classical, it is sound against a cheating unbounded quantum prover and computational zero-knowledge even if the verifier is allowed a superposition attack. Finally, we consider multiparty computation and show that for the most general type of attack, simulation based...... of information. In this paper, we introduce a fundamentally new model of quantum attacks on classical cryptographic protocols, where the adversary is allowed to ask several classical queries in quantum superposition. This is a strictly stronger attack than the standard one, and we consider the security...

  19. Genetic Algorithms for Agent-Based Infrastructure Interdependency Modeling and Analysis

    2007-03-01

    Today’s society relies greatly upon an array of complex national and international infrastructure networks such as transportation, electric power, telecommunication, and financial networks. This paper describes initial research combining agent-based infrastructure modeling software and genetic algorithms (GAs) to help optimize infrastructure protection and restoration decisions. This research proposes to apply GAs to the problem of infrastructure modeling and analysis in order to determine the optimum assets to restore or protect from attack or other disaster. This research is just commencing and therefore the focus of this paper is the integration of a GA optimization method with a simulation through the simulation’s agents.

    This paper examines the impact of public infrastructure on industrial location when increasing returns are present. Poor infrastructure implies costs of Samuelson's `iceberg' form and alter trade both within and between countries. Trade integration implies that firms tend to locate in countries with better infrastructure so that regional policies that affect the level of public infrastructure influence economic geography. The effectiveness of such policies decreases when infrastructure improv...

    The simulation software for the ATLAS Experiment at the Large Hadron Collider is being used for large-scale production of events on the LHC Computing Grid. This simulation requires many components, from the generators that simulate particle collisions, through packages simulating the response of the various detectors and triggers. All of these components come together under the ATLAS simulation infrastructure. In this paper, that infrastructure is discussed, including that supporting the detector description, interfacing the event generation, and combining the GEANT4 simulation of the response of the individual detectors. Also described are the tools allowing the software validation, performance testing, and the validation of the simulated output against known physics processes.

    Depleted Uranium (DU) is a byproduct of the uranium enrichment for producing nuclear reactor or nuclear weapon. DU is used in the military as an armor-piercing projectile due to its hardness, strength, and density. A lot of DU weapons were fired in the Gulf War, and bring about critical environmental and internal contamination. Therefore, DU becomes suddenly a hot issue. Some toxicological problems after DU weapons attacked have been reviewed, which include features of internal DU contamination. Hazard of wound contamination and inhalation with insoluble uranium, and other urgent toxicological issues. The healthy effects of implanted with depleted uranium pellets were illustrated in particular

  7. WILD PIG ATTACKS ON HUMANS

    2013-04-12

    Attacks on humans by wild pigs (Sus scrofa) have been documented since ancient times. However, studies characterizing these incidents are lacking. In an effort to better understand this phenomenon, information was collected from 412 wild pig attacks on humans. Similar to studies of large predator attacks on humans, data came from a variety of sources. The various attacks compiled occurred in seven zoogeographic realms. Most attacks occurred within the species native range, and specifically in rural areas. The occurrence was highest during the winter months and daylight hours. Most happened under non-hunting circumstances and appeared to be unprovoked. Wounded animals were the chief cause of these attacks in hunting situations. The animals involved were typically solitary, male and large in size. The fate of the wild pigs involved in these attacks varied depending upon the circumstances, however, most escaped uninjured. Most human victims were adult males traveling on foot and alone. The most frequent outcome for these victims was physical contact/mauling. The severity of resulting injuries ranged from minor to fatal. Most of the mauled victims had injuries to only one part of their bodies, with legs/feet being the most frequent body part injured. Injuries were primarily in the form of lacerations and punctures. Fatalities were typically due to blood loss. In some cases, serious infections or toxemia resulted from the injuries. Other species (i.e., pets and livestock) were also accompanying some of the humans during these attacks. The fates of these animals varied from escaping uninjured to being killed. Frequency data on both non-hunting and hunting incidents of wild pig attacks on humans at the Savannah River Site, South Carolina, showed quantitatively that such incidents are rare.

    2007-01-01

    For many years CERN had a very sophisticated print server infrastructure [13] which supported several different protocols (AppleTalk, IPX and TCP/IP) and many different printing standards. Today’s situation differs a lot: we have a much more homogenous network infrastructure, where TCP/IP is used everywhere and we have less printer models, which almost all work using current standards (i.e. they all provide PostScript drivers). This change gave us the possibility to review the printing architecture aiming at simplifying the infrastructure in order to achieve full automation of the service. The new infrastructure offers both: LPD service exposing print queues to Linux and Mac OS X computers and native printing for Windows based clients. The printer driver distribution is automatic and native on Windows and automated by custom mechanisms on Linux, where the appropriate Foomatic drivers are configured. Also the process of printer registration and queue creation is completely automated following the printer ...

    2008-11-01

    Full Text Available A mobile ad hoc network (MANET is a dynamic wireless network that can be formed without any pre-existing infrastructure in which each node can act as a router. MANET has no clear line of defense, so, it is accessible to both legitimate network users and malicious attackers. In the presence of malicious nodes, one of the main challenges in MANET is to design the robust security solution that can protect MANET from various routing attacks. Different mechanisms have been proposed using various cryptographic techniques to countermeasure the routing attacks against MANET. However, these mechanisms are not suitable for MANET resource constraints, i.e., limited bandwidth and battery power, because they introduce heavy traffic load to exchange and verifying keys. In this paper, the current security issues in MANET are investigated. Particularly, we have examined different routing attacks, such as flooding, blackhole, link spoofing, wormhole, and colluding misrelay attacks, as well as existing solutions to protect MANET protocols.

  13. Nanotechnology and MEMS-based systems for civil infrastructure safety and security: Opportunities and challenges

    Robinson, Nidia; Saafi, Mohamed

    2006-03-01

    Critical civil infrastructure systems such as bridges, high rises, dams, nuclear power plants and pipelines present a major investment and the health of the United States' economy and the lifestyle of its citizens both depend on their safety and security. The challenge for engineers is to maintain the safety and security of these large structures in the face of terrorism threats, natural disasters and long-term deterioration, as well as to meet the demands of emergency response times. With the significant negative impact that these threats can have on the structural environment, health monitoring of civil infrastructure holds promise as a way to provide information for near real-time condition assessment of the structure's safety and security. This information can be used to assess the integrity of the structure for post-earthquake and terrorist attacks rescue and recovery, and to safely and rapidly remove the debris and to temporary shore specific structural elements. This information can also be used for identification of incipient damage in structures experiencing long-term deterioration. However, one of the major obstacles preventing sensor-based monitoring is the lack of reliable, easy-to-install, cost-effective and harsh environment resistant sensors that can be densely embedded into large-scale civil infrastructure systems. Nanotechnology and MEMS-based systems which have matured in recent years represent an innovative solution to current damage detection systems, leading to wireless, inexpensive, durable, compact, and high-density information collection. In this paper, ongoing research activities at Alabama A&M University (AAMU) Center for Transportation Infrastructure Safety and Security on the application of nanotechnology and MEMS to Civil Infrastructure for health monitoring will presented. To date, research showed that nanotechnology and MEMS-based systems can be used to wirelessly detect and monitor different damage mechanisms in concrete structures

    Different scaling properties for the complexity of bidirectional synchronization and unidirectional learning are essential for the security of neural cryptography. Incrementing the synaptic depth of the networks increases the synchronization time only polynomially, but the success of the geometric attack is reduced exponentially and it clearly fails in the limit of infinite synaptic depth. This method is improved by adding a genetic algorithm, which selects the fittest neural networks. The probability of a successful genetic attack is calculated for different model parameters using numerical simulations. The results show that scaling laws observed in the case of other attacks hold for the improved algorithm, too. The number of networks needed for an effective attack grows exponentially with increasing synaptic depth. In addition, finite-size effects caused by Hebbian and anti-Hebbian learning are analyzed. These learning rules converge to the random walk rule if the synaptic depth is small compared to the square root of the system size.

  3. Vulnerability to terrorist attacks in European electricity decarbonisation scenarios: Comparing renewable electricity imports to gas imports

    International Nuclear Information System (INIS)

    The decarbonised future European electricity system must remain secure: reliable electricity supply is a prerequisite for the functioning of modern society. Scenarios like Desertec, which partially rely on solar power imports from the Middle East and North Africa, may be attractive for decarbonisation, but raise concerns about terrorists interrupting supply by attacking the long, unprotected transmission lines in the Sahara. In this paper, I develop new methods and assess the European vulnerability to terrorist attacks in the Desertec scenario. I compare this to the vulnerability of today's system and a decarbonisation scenario in which Europe relies on gas imports for electricity generation. I show that the vulnerability of both gas and electricity imports is low, but electricity imports are more vulnerable than gas imports, due to their technical characteristics. Gas outages (and, potentially, resulting blackouts) are the very unlikely consequence even of very high-number attacks against the gas import system, whereas short blackouts are the potential consequence of a few attacks against the import electricity lines. As the impacts of all except extreme attacks are limited, terrorists cannot attack energy infrastructure and cause spectacular, fear-creating outages. Both gas and electricity import infrastructure are thus unattractive and unlikely terrorist targets. - Highlights: • A comparison of terrorism risks of importing solar power and gas for power generation. • Both scenarios show low vulnerability to terrorist attacks. • Within low vulnerabilities, gas imports are less vulnerable than electricity imports. • Causing spectacular, large and long outages is very difficult for attacker. • The attractiveness of gas and power import infrastructure as terrorist target is low

    Full Text Available The decrease of the cerebral blood flow below the threshold of autoregulation led to changes of cerebral ischemia and necrosis that traduce in signs and symtoms of focal neurologic dysfunction called acute cerebrovascular symdrome (ACS or stroke. Two big groups according to its etiology are included in this category the hemorragic that constitue a 20% and the ischemic a 80% of cases. Great interest has wom the ischemic ACS because of its high social burden, being the third cause of no violent death in the world and the first of disability. Many risk factors favor the presentation of these events and some of them are susceptible of modification and therfore are objetives of primary prevention just as the control of diabetes, hypertension and the practice of healthy habits of life. The advances in the knowledge of the physiopatology, had taken to sustantial change in the nomenclature and management of ischemic ACS. Within these changes it was substituted the term cerebrovascular accident fo acute stroke, making emphasis in the key rol of a timely management with goals of time similiar to the acute coronary syndrome. It was redefined the time of acute ischemic attack to a one hour. Once stablished the cerebrovascular attack the semiology of symtoms with frecuency will led us make a topographic diagnosis of the in injury that joined to the cerebral TAC will allow us to exclude an hemorragic event and to start the treatment. In the management of these patients its essential the coordination of the differents teams of work, from the early recognition of symtoms on the part of patients andthe family, the rapid activation and response of emergency systems and the gearing of health care institutions. Are pillars of treatment: the abcde of reanimatiion, to avoid the hiperpirexis, the seizures, the hipoglicemy, the hiperglicemy, to achieve the thrombolysis in the first three hours of the begining of symtoms, to use antiplatelets, antithrombotic profilaxis

  6. A Novel Solution for Discriminating Wormhole Attacks in MANETs from Congested Traffic using RTT and Transitory Buffer

    Directory of Open Access Journals (Sweden)

    Maria Sebastian

    2013-06-01

    Full Text Available Nowadays, the computing and communication services are accessed while on the move. Setting up of fixed access points and backbone infrastructure is not always viable. So in order to provide communication where there is lack of infrastructure or inconvenience in using the existing infrastructure, Mobile Adhoc Networks (MANETs are used. This inherent flexibility allows MANETs to be used for a wide range of applications such as rescue operations, military applications, vehicular communication, and business meetings. As there is no apriori trust relationship between the nodes of an ad hoc network and basic network functions like packet forwarding and routing are performed by the available nodes, security is an essential component in MANETs. Various attacks in MANETs are blackhole attack, byzantine attack, resource consumption attack, rushing attack, and wormhole attack. Wormhole attack is a severe threat among the other threats in MANET. Existing solutions to detect wormhole attacks include Packet Leashes, SECTOR, DelPHI, RTT-TC, TTM, etc. These solutions require special hardware or strict synchronized clocks or cause message overhead. Some solutions do not locate the wormhole, and some other may generate false alarms or does not consider network congestion into account. In this paper, wormhole attack detection is proposed based on RTT between successive nodes and congestion detection mechanism. If the RTT between two successive nodes is higher than the threshold value, a wormhole attack is suspected. If a wormhole is suspected, node's transitory buffer is probed to determine whether the long delay between the nodes is due to wormhole or not, as delays can be caused due to congestion or by queuing delays. The proposed method prevents both the hidden and the exposed attack. Advantage of our proposed solution is that it does not require any specialized hardware or synchronized clocks.

    2013-03-12

    Air Products and Chemicals, Inc. has completed a comprehensive, multiyear project to demonstrate a hydrogen infrastructure in California. The specific primary objective of the project was to demonstrate a model of a real-world retail hydrogen infrastructure and acquire sufficient data within the project to assess the feasibility of achieving the nation's hydrogen infrastructure goals. The project helped to advance hydrogen station technology, including the vehicle-to-station fueling interface, through consumer experiences and feedback. By encompassing a variety of fuel cell vehicles, customer profiles and fueling experiences, this project was able to obtain a complete portrait of real market needs. The project also opened its stations to other qualified vehicle providers at the appropriate time to promote widespread use and gain even broader public understanding of a hydrogen infrastructure. The project engaged major energy companies to provide a fueling experience similar to traditional gasoline station sites to foster public acceptance of hydrogen. Work over the course of the project was focused in multiple areas. With respect to the equipment needed, technical design specifications (including both safety and operational considerations) were written, reviewed, and finalized. After finalizing individual equipment designs, complete station designs were started including process flow diagrams and systems safety reviews. Material quotes were obtained, and in some cases, depending on the project status and the lead time, equipment was placed on order and fabrication began. Consideration was given for expected vehicle usage and station capacity, standard features needed, and the ability to upgrade the station at a later date. In parallel with work on the equipment, discussions were started with various vehicle manufacturers to identify vehicle demand (short- and long-term needs). Discussions included identifying potential areas most suited for hydrogen fueling

    Full Text Available Mobile wirelesses networks are generally open to various attacks like information and physical security attacks than fixed wired networks. Securing wireless ad hoc networks is particularly more difficult for many of the reasons for example vulnerability of channels and nodes, absence of infrastructure, dynamically changing topology etc. After that we initialize the number of nodes. Then implement protocol for the communication of nodes. Due to these protocols communication start. And this will be then implemented in CRNs which stand for cognitive radio network in which channel sensing is done. By the use of CRN security will be improved and performance will be enhanced. Find the malicious nodes occur in the network. One malicious node uses routing protocol to claim itself of being shortest path to last node but drops routing packets and doesn’t send packets to its neighbors. In last evaluate the parameters.

    Many methods have been developed to secure the network infrastructure and communication over the Internet. Intrusion detection is a relatively new addition to such techniques. Intrusion detection systems (IDS) are used to find out if someone has intrusion into or is trying to get it the network. One big problem is amount of Intrusion which is increasing day by day. We need to know about network attack information using IDS, then analysing the effect. Due to the nature of IDSs which are solely signature based, every new intrusion cannot be detected; so it is important to introduce artificial intelligence (AI) methods / techniques in IDS. Introduction of AI necessitates the importance of normalization in intrusions. This work is focused on classification of AI based IDS techniques which will help better design intrusion detection systems in the future. We have also proposed a support vector machine for IDS to detect Smurf attack with much reliable accuracy.

    Full Text Available s a result of the increased dependency on obtaining information and connecting each computer togetherfor ease of access/communication, organizations risk being attacked and losing private information through breaches or insecure business activities. To help protect organizations and their assets, companies need to develop a strong understanding of the risks imposed on their company and the security solutions designed to prevent/minimize vulnerabilities. To reduce the impact threats have on a network, organizations need to: design a defense layer system that provides multiple instances of protection to prevent unauthorized access to core information, implement a strong network hardware/intrusion prevention system, and create all-inclusive network/security policies that detail user rules and company rights. In order to enhance the overall security of a basic infrastructure, this paper will provide a detailed look into gathering the organizational requirements, designing and implementing a secure physical network layout, and selecting the standards needed to prevent unauthorized access.

  18. A Simple Hybrid Wormhole Algorithm for Detection and Removal of Wormhole Attacks for Secure Routing In Ad Hoc Wireless Networks

    A.VANI,

    2011-06-01

    Full Text Available The infrastructure of a Mobile Ad hoc Network (MANET has no routers for routing, and all nodes must share the same routing protocol to assist each other when transmitting messages. However, almost allcommon routing protocols at present consider performance as first priority, and have little defense capability against the malicious nodes. Many researches have proposed various protocols of higher safety to defend against attacks; however, each has specific defense objects, and is unable to defend against particular attacks. Of all the types of attacks, the wormhole attack poses the greatest threat and is very difficult to prevent; therefore, this paper focuses on the wormhole attack, by combing three techniques. So that our proposed scheme has three techniques based on hop count, decision anomaly, neighbor list count methods are combined to detect andisolate wormhole attacks in ad hoc networks. That manages how the nodes are going to behave and which to route the packets in secured way.

    Modern world builds on the resilience of interdependent infrastructures characterized as complex networks. Recently, a framework for analysis of interdependent networks has been developed to explain the mechanism of resilience in interdependent networks. Here we extend this interdependent network model by considering flows in the networks and study the system's resilience under different attack strategies. In our model, nodes may fail due to either overload or loss of interdependency. Under the interaction between these two failure mechanisms, it is shown that interdependent scale-free networks show extreme vulnerability. The resilience of interdependent SF networks is found in our simulation much smaller than single SF network or interdependent SF networks without flows.

  1. RESIST SRP AGAINST WORMHOLE ATTACK

    2013-06-01

    Full Text Available Ad-hoc networks refer to temporary or interim networks which form for special purposes. Actually they are wireless networks with mobile nodes. These networks use no network assisting element for path routing and in these networks available nodes are responsible for path routing. Therefore when malicious nodes want to find a way to interfere with the path routing then the existence of a secure route protocol (SRP can prevent the interference. SRP protocol is one of the secure algorithms of path routing protocol but it is notresistant against wormhole attack. Wormhole attack is considered as a subtle attack in which two malicious nodes make a short connection in network's topology through private or implicit connection and represent two non neighbor nodes as neighbors and prevent the correctoperation of path routing protocol by using this method. One of the methods of preventing wormhole attack is by using packet leashes. We try to decrease the wormhole attack occurrence in this routing protocol by a kind of packet leashes called temporal leashes. We alsowill minimize problems resulting from using temporal leashes by different methods and modifications in its structure.

  2. Analysis of AODV and DSR in Presence of Wormhole Attack in Mobile Ad-hoc Network

    2010-11-01

    Full Text Available An ad hoc network is a collection of mobile nodes that dynamically form a temporary network. It operates without the use of existing infrastructure. As mobile ad hoc network applications are deployed, security emerges as a central requirement. In this paper, we introduce the wormhole attack, a severe security attack in ad hocnetworks that is particularly challenging to defend against. The wormhole attack is possible even if the attacker has not compromised any hosts and even if all communication provides authenticity and confidentiality. In the wormhole attack, an attacker records packets (or bits at one location in the network, tunnels them (possiblyselectively to another location, and retransmits them there into the network. The wormhole attack can form a serious threat in wireless networks, especially against many ad hoc network routing protocols and locationbased wireless security systems. This paper analyses the performance of AODV and DSR routing protocols with and without wormhole attack. This would be a great help for the people conducting research on real world problems in MANET security.

  3. Study of DSR and AODV under Sinkhole Attack and Its Proposed Prevention Technique

    2014-03-01

    Full Text Available Mobile Ad-hoc Networks (MANET are wireless mobile nodes that communicate without any predefined infrastructure. This allows MANETs to be easily setup in geographical and terrestrial constraints. To achieve this kind of communication MANET routing protocols play an important role. Two routing protocols, DSR and AODV are studied in detail. This basic trait of a MANET makes its routing protocols very vulnerable to security attacks. One such attack is the ‘Sinkhole’ attack which lures packets towards the sinkhole node. A malicious Sinkhole node severely degrades the network once the attack is in progress. This paper describes two of the popular MANET routing protocols, DSR and AODV and the sinkhole attack on these protocols. Prior research carried out to prevent the sinkhole attack is analyzed. Multiple procedures are documented to prevent and mitigate the problem of Sinkhole in MANETs. The proposed solution relies on tackling the sequence number discontinuity to contain Sinkhole attacks. A prevention technique is proposed that relies on the fact that the sequence number discontinuity if tackled can go a long way in containing Sinkhole attacks.

  4. Radiation protection infrastructure

    International Nuclear Information System (INIS)

    A prerequisite for the safe use of ionizing radiation in a country is the availability of an adequate infrastructure to achieve the desired degree of protection. The extent of such an infrastructure, generally comprising regulatory mechanisms and technical capabilities for application and enforcement of regulations, has to be commensurate with the stage of technological development. The expanding application of ionizing radiation in medicine, industry and research calls for vigorous promotion of effective radiation protection efforts, not only to prevent any unsafe practices but also to assess correctly and provide authoritative information on the safety of adopted practices. Experience reveals that radiation protection practices vary considerably from one country to another. The regulatory structures and type of organization with regard to radiation protection are very different, depending on a number of factors such as the constitutional framework, the legal and administrative systems of the country concerned, the state of technical development, the status of application of radiation sources, the existence of research and associated institutions, and the technical skills and financial resources available. Radiation protection principles evolve with time as further experience is gained and as new research evidence becomes available. Regulation of radiation protection has to take account of such changes and adapt to changing conditions. Forty-eight papers from 29 Member States and two International Organizations were presented in nine scientific sessions. Topics included radiation protection regulation and licensing notification, registration, inspection and control programmes, education and training, the role of supporting institutions such as national laboratories and research institutes, the role of professional associations, the contribution of radiation protection services, and international activities. A concluding panel addressed development strategies to

    2014-12-01

    The management of water is among the most important attributes of urbanization. Provision of sufficient quantities and quality of freshwater, treatment and disposal of wastewater and flood protection are critical for urban sustainability. Over the last century, two major shifts in water management paradigms have occurred, the first to improve public health with the provision of infrastructure for centralized sanitary effluent collection and treatment, and the rapid drainage and routing of stormwater. A current shift in paradigm is now occurring in response to the unintended consequences of sanitary and stormwater management, which have degraded downstream water bodies and shifted flood hazard downstream. Current infrastructure is being designed and implemented to retain, rather than rapidly drain, stormwater, with a focus on infiltration based methods. In urban areas, this amounts to a shift in hydrologic behavior to depression focused recharge. While stormwater is defined as surface flow resulting from developed areas, an integrated hydrologic systems approach to urban water management requires treatment of the full critical zone. In urban areas this extends from the top of the vegetation and building canopy, to a subsurface depth including natural soils, fill, saprolite and bedrock. In addition to matric and network flow in fracture systems, an urban "karst" includes multiple generations of current and past infrastructure, which has developed extensive subsurface pipe networks for supply and drainage, enhancing surface/groundwater flows and exchange. In this presentation, Band will discuss the need to focus on the urban critical zone, and the development and adaptation of new modeling and analytical approaches to understand and plan green infrastructure based on surface/groundwater/ecosystem interactions, and implications for the restoration and new design of cities.

    Full Text Available Throughout its history, the oil and gas industry has been a subject of environmental protests, labour disputes, tensions with local communities, and it has also been a target of various violent activities ranging from vandalism to political violence, which have impinged on the security of oil industry workers and interfered with operational activities of oil companies on numerous occasions. Although a considerable number of attacks on oil and gas infrastructure occurred over the course of the industry’s existence, most of those attacks were directed against onshore petroleum targets. Compared to onshore petroleum infrastructure, attacks on offshore oil and gas installations are relatively rare. The following chronology provides details of attacks, unlawful interferences, and security incidents involving offshore oil and gas installations that happened between 1975 and 2010.

    2015-02-01

    The nuclear hybrid energy concept is becoming a reality for the US energy infrastructure where combinations of the various potential energy sources (nuclear, wind, solar, biomass, and so on) are integrated in a hybrid energy system. This paper focuses on challenges facing a hybrid system with a Small Modular Reactor at its core. The core of the paper will discuss efforts required to develop supervisory control center that collects data, supports decision-making, and serves as an information hub for supervisory control center. Such a center will also be a model for integrating future technologies and controls. In addition, advanced operations research, thermal cycle analysis, energy conversion analysis, control engineering, and human factors engineering will be part of the supervisory control center. Nuclear hybrid energy infrastructure would allow operators to optimize the cost of energy production by providing appropriate means of integrating different energy sources. The data needs to be stored, processed, analyzed, trended, and projected at right time to right operator to integrate different energy sources.

    2013-03-12

    Air Products and Chemicals, Inc. has completed a comprehensive, multiyear project to demonstrate a hydrogen infrastructure in California. The specific primary objective of the project was to demonstrate a model of a “real-world” retail hydrogen infrastructure and acquire sufficient data within the project to assess the feasibility of achieving the nation’s hydrogen infrastructure goals. The project helped to advance hydrogen station technology, including the vehicle-to-station fueling interface, through consumer experiences and feedback. By encompassing a variety of fuel cell vehicles, customer profiles and fueling experiences, this project was able to obtain a complete portrait of real market needs. The project also opened its stations to other qualified vehicle providers at the appropriate time to promote widespread use and gain even broader public understanding of a hydrogen infrastructure. The project engaged major energy companies to provide a fueling experience similar to traditional gasoline station sites to foster public acceptance of hydrogen. Work over the course of the project was focused in multiple areas. With respect to the equipment needed, technical design specifications (including both safety and operational considerations) were written, reviewed, and finalized. After finalizing individual equipment designs, complete station designs were started including process flow diagrams and systems safety reviews. Material quotes were obtained, and in some cases, depending on the project status and the lead time, equipment was placed on order and fabrication began. Consideration was given for expected vehicle usage and station capacity, standard features needed, and the ability to upgrade the station at a later date. In parallel with work on the equipment, discussions were started with various vehicle manufacturers to

    Full Text Available Wireless or Mobile Networks emerged to replace the wired networks. The new generation of wireless network is relatively different than the comparisons of traditional wired network in many aspects like resource sharing, power usage, reliability, efficient, ease to handle, network infrastructure and routing protocols, etc. Mobile Ad-Hoc Networks (MANETs are autonomous and decentralized wireless systems. MANETs consist of mobile nodes that are free in moving in and out in the network. There is an increasing threat of attacks on the MANET. Thus, in MANET black hole attack are mostly serious security attacks. In this paper, we have examined certain black hole attacks prevention routing protocols. Finally, we have compared some routing protocols using some important parameters and then addressed major issues related to this.

  14. Neighbor Attack And Detection Mechanism In Mobile Ad-Hoc Networks

    2012-04-01

    Full Text Available In Mobile Ad-Hoc Networks (MANETs, security is one of the most important concerns because a MANETs system is much more vulnerable to attacks than a wired or infrastructure-based wireless network. Designing an effective security protocol for MANET is a very challenging task. This is mainlydue to the unique characteristics of MANETs, namely shared broadcast radio channel, insecure operatingenvironment, lack of central authority, lack of association among users, limited availability of resources, and physical vulnerability. In this paper we present simulation based study of the impact of neighbor attack on mesh-based Mobile Ad-Hoc Network (MANET. And also we study the number of attackers and position affects the performance metrics such as packet delivery ratio and throughput. The study enables us to propose a secure neighbor detection mechanism (SNDM. A generic detection mechanism against neighbor attack for On Demand Routing Protocols is simulated on GlomoSim environment.

  15. The Derivation and Use of a Scalable Model for Network Attack Identification and Path Prediction

    Directory of Open Access Journals (Sweden)

    2008-04-01

    Full Text Available The rapid growth of the Internet has triggered an explosion in the number of applications that leverage its capabilities. Unfortunately, many are designed to burden or destroy the capabilities of their peers and the network's infrastructure. Hence, considerable effort has been focused on detecting and predicting the security breaches they propagate. However, the enormity of the Internet poses a formidable challenge to analyzing such attacks using scalable models. Furthermore, the lack of complete information on network vulnerabilities makes forecasting the systems that may be exploited by such applications in the future very hard. This paper presents a technique for deriving a scalable model for representing network attacks, and its application to identify actual attacks with greater certainty amongst false positives and false negatives. It also presents a method to forecast the propagation of security failures proliferated by an attack over time and its likely targets in the future.

    The expected urbanization of the planet in the coming century coupled with aging infrastructure in developed regions, increasing complexity of man-made systems, and pressing climate change impacts have created opportunities for reassessing the role of infrastructure and technologies in cities and how they contribute to greenhouse gas (GHG) emissions. Modern urbanization is predicated on complex, increasingly coupled infrastructure systems, and energy use continues to be largely met from fossil fuels. Until energy infrastructures evolve away from carbon-based fuels, GHG emissions are critically tied to the urbanization process. Further complicating the challenge of decoupling urban growth from GHG emissions are lock-in effects and interdependencies. This paper synthesizes state-of-the-art thinking for transportation, fuels, buildings, water, electricity, and waste systems and finds that GHG emissions assessments tend to view these systems as static and isolated from social and institutional systems. Despite significant understanding of methods and technologies for reducing infrastructure-related GHG emissions, physical, institutional, and cultural constraints continue to work against us, pointing to knowledge gaps that must be addressed. This paper identifies three challenge themes to improve our understanding of the role of infrastructure and technologies in urbanization processes and position these increasingly complex systems for low-carbon growth. The challenges emphasize how we can reimagine the role of infrastructure in the future and how people, institutions, and ecological systems interface with infrastructure.

  17. FLOODING ATTACK AWARE SECURE AODV

    Directory of Open Access Journals (Sweden)

    S. Madhavi

    2013-01-01

    Full Text Available Providing security in a Mobile Ad hoc Network (MANET is a challenging task due to its inherent nature. Flooding is a type of Denial of Service (DoS attack in MANET. Intentional flooding may lead to disturbances in the networking operation. This kind of attack consumes battery power, storage space and bandwidth. Flooding the excessive number of packets may degrade the performance of the network. This study considers hello flooding attack. As the hello packets are continuously flooded by the malicious node, the neighbor node is not able to process other packets. The functioning of the legitimate node is diverted and destroys the networking operation. Absence of hello packet during the periodical hello interval may lead to wrong assumption that the neighbor node has moved away. So one of the intermediate neighbor nodes sends Route Error (RERR message and the source node reinitiates the route discovery process. In a random fashion the hello interval values are changed and convey this information to other nodes in the network in a secured manner. This study identifies and prevents the flooding attack. This methodology considers the performance parameters such as packet delivery ratio, delay and throughput. This algorithm is implemented in Secure AODV and tested in ad hoc environment. The result of the proposed algorithm decreases the control overhead by 2%.

    One significant drawback to currently available security products is their inabilty to correlate diverse sensor input. For instance, by only using network intrusion detection data, a root kit installed through a weak username-password combination may go unnoticed. Similarly, an administrator may never make the link between deteriorating response times from the database server and an attacker exfiltrating trusted data, if these facts aren't presented together. Current Security Information Management Systems (SIMS) can collect and represent diverse data but lack sufficient correlation algorithms. By using a Process Query System, we were able to quickly bring together data flowing from many sources, including NIDS, HIDS, server logs, CPU load and memory usage, etc. We constructed PQS models that describe dynamic behavior of complicated attacks and failures, allowing us to detect and differentiate simultaneous sophisticated attacks on a target network. In this paper, we discuss the benefits of implementing such a multistage cyber attack detection system using PQS. We focus on how data from multiple sources can be combined and used to detect and track comprehensive network security events that go unnoticed using conventional tools.

  1. [Polygraphy of a panic attack].

    2001-09-01

    We studied a 24-year old female patient with Type 1 diabetes mellitus suffering for 4 weeks from a major depressive episode combined with panic disorder without agoraphobia. A spontaneous panic attack was serendipitously recorded by polygraph while the subject was at rest. Electrocardiogram, finger blood-flow, respiratory rhythm and muscle tone (forearm, forehead) were recorded. A triphasic course consisting of a "dynamic phase" (appr. 80 s) preceded by a discrete "initial phase" (appr. 140 s) and a "declining phase" (appr. 180 s) was observed. The dynamic phase is characterized by an acute increase of fingertip vasoconstriction and heart rate. The patient was not aware of the panic attack before the dynamic phase. The recognisable central regulation confirms previously published findings indicating a sympathetic-norepinephrine activation at the beginning of the panic attack without activating the musculoskeletal system. Furthermore, a paradoxical phenomenon involving heart and respiratory rate was observed before the onset of anxiety, i.e. an increase of the heart rate and a simultaneous decline of the respiratory rate, suggesting a non-antagonistic regulation of the ergotropic-trophotropic system. The autonomic state of the patient points to a lability in homeostasis from which panic attacks as a form of CNS response could develop. PMID:11572106

    2016-01-01

    Vulnerabilities of complex networks have became a trend topic in complex systems recently due to its real world applications. Most real networks tend to be very fragile to high betweenness adaptive attacks. However, recent contributions have shown the importance of interconnected nodes in the integrity of networks and module-based attacks have appeared promising when compared to traditional malicious non-adaptive attacks. In the present work we deeply explore the trade-off associated with attack procedures, introducing a generalized robustness measure and presenting an attack performance index that takes into account both robustness of the network against the attack and the run-time needed to obtained the list of targeted nodes for the attack. Besides, we introduce the concept of deactivation point aimed to mark the point at which the network stops to function properly. We then show empirically that non-adaptive module-based attacks perform better than high degree and betweenness adaptive attacks in networks ...

    The capability to assess the impacts of large-scale biological attacks and the efficacy of containment policies is critical and requires knowledge-intensive reasoning about social response and disease transmission within a complex social system. There is a close linkage among social networks, transportation networks, disease spread, and early detection. Spatial dimensions related to public gathering places such as hospitals, nursing homes, and restaurants, can play a major role in epidemics [Klovdahl et. al. 2001]. Like natural epidemics, bioterrorist attacks unfold within spatially defined, complex social systems, and the societal and networked response can have profound effects on their outcome. This paper focuses on bioterrorist attacks, but the model has been applied to emergent and familiar diseases as well.

    2012-03-30

    This is the final report for a grant-funded project to financially assist and otherwise provide support to projects that increase E85 infrastructure in Michigan at retail fueling locations. Over the two-year project timeframe, nine E85 and/or flex-fuel pumps were installed around the State of Michigan at locations currently lacking E85 infrastructure. A total of five stations installed the nine pumps, all providing cost share toward the project. By using cost sharing by station partners, the $200,000 provided by the Department of Energy facilitated a total project worth $746,332.85. This project was completed over a two-year timetable (eight quarters). The first quarter of the project focused on project outreach to station owners about the incentive on the installation and/or conversion of E85 compatible fueling equipment including fueling pumps, tanks, and all necessary electrical and plumbing connections. Utilizing Clean Energy Coalition (CEC) extensive knowledge of gasoline/ethanol infrastructure throughout Michigan, CEC strategically placed these pumps in locations to strengthen the broad availability of E85 in Michigan. During the first and second quarters, CEC staff approved projects for funding and secured contracts with station owners; the second through eighth quarters were spent working with fueling station owners to complete projects; the third through eighth quarters included time spent promoting projects; and beginning in the second quarter and running for the duration of the project was spent performing project reporting and evaluation to the US DOE. A total of 9 pumps were installed (four in Elkton, two in Sebewaing, one in East Lansing, one in Howell, and one in Whitmore Lake). At these combined station locations, a total of 192,445 gallons of E85, 10,786 gallons of E50, and 19,159 gallons of E30 were sold in all reporting quarters for 2011. Overall, the project has successfully displaced 162,611 gallons (2,663 barrels) of petroleum, and reduced

    Highly lethal terrorist attacks, which we define as those killing 21 or more people, account for 50% of the total number of people killed in all terrorist attacks combined, yet comprise only 3.5% of terrorist attacks. Given the disproportionate influence of these incidents, uncovering systematic patterns in attacks that precede and anticipate these highly lethal attacks may be of value for understanding attacks that exact a heavy toll on life. Here we examined whether the activity of terrorist groups escalates--both in the number of people killed per attack and in the frequency of attacks--leading up to highly lethal attacks. Analyses of terrorist attacks drawn from a state-of-the-art international terrorism database (The Global Terrorism Database) showed evidence for both types of escalation leading up to highly lethal attacks, though complexities to the patterns emerged as well. These patterns of escalation do not emerge among terrorist groups that never commit a highly lethal attack.

    Sandia National Laboratories hosted a workshop on the future of infrastructure security on February 27-28, 2013, in Albuquerque, NM. The 17 participants came from backgrounds as diverse as federal policy, the insurance industry, infrastructure management, and technology development. The purpose of the workshop was to surface key issues, identify directions forward, and lay groundwork for cross-sectoral and cross-disciplinary collaborations. The workshop addressed issues such as the problem space (what is included in infrastructure problems?), the general types of threats to infrastructure (such as acute or chronic, system-inherent or exogenously imposed) and definitions of secure and resilient infrastructures. The workshop concluded with a consideration of stakeholders and players in the infrastructure world, and identification of specific activities that could be undertaken by the Department of Homeland Security (DHS) and other players.

    broadening of the avenues of possible inquiry could be timely in relation to Facebook. What can we learn from Facebook as a venue for organizing in emergencies or around public issues? In order start answering this question I examine a recent controversy over plans to build a new road-pricing infrastructure...... to curb congestion in Copenhagen. The so-called payment ring project has now been officially dropped, but only after becoming one of the most heated topics in Danish politics in recent years. Thousands of people mobilized on Facebook pages for and against the actualization of the payment ring. I suggest...... that such issue-oriented pages represent an interesting reappropriation of the Facebook platform, whose ’pages’ feature is mainly targeted at commercial brands and other institutions. The majority of the pages founded in reaction to the payment ring were marked by sharp protests, something that generates...

    The objective of Energy Transmission and Infrastructure Northern Ohio (OH) was to lay the conceptual and analytical foundation for an energy economy in northern Ohio that will: • improve the efficiency with which energy is used in the residential, commercial, industrial, agricultural, and transportation sectors for Oberlin, Ohio as a district-wide model for Congressional District OH-09; • identify the potential to deploy wind and solar technologies and the most effective configuration for the regional energy system (i.e., the ratio of distributed or centralized power generation); • analyze the potential within the district to utilize farm wastes to produce biofuels; • enhance long-term energy security by identifying ways to deploy local resources and building Ohio-based enterprises; • identify the policy, regulatory, and financial barriers impeding development of a new energy system; and • improve energy infrastructure within Congressional District OH-09. This objective of laying the foundation for a renewable energy system in Ohio was achieved through four primary areas of activity: 1. district-wide energy infrastructure assessments and alternative-energy transmission studies; 2. energy infrastructure improvement projects undertaken by American Municipal Power (AMP) affiliates in the northern Ohio communities of Elmore, Oak Harbor, and Wellington; 3. Oberlin, OH-area energy assessment initiatives; and 4. a district-wide conference held in September 2011 to disseminate year-one findings. The grant supported 17 research studies by leading energy, policy, and financial specialists, including studies on: current energy use in the district and the Oberlin area; regional potential for energy generation from renewable sources such as solar power, wind, and farm-waste; energy and transportation strategies for transitioning the City of Oberlin entirely to renewable resources and considering pedestrians, bicyclists, and public transportation as well as drivers

    Full Text Available The article discusses the concept of "institutional infrastructure" and clarifies its essential content in relation to market cars. In terms of the industry market the main purpose of the institutional infrastructure is achieving the maximum economic benefit within limited resources. The main tasks that need to be solved in order to achieve this goal were formulated. We have developed and proved structurally-logical chart of the elements of the institutional infrastructure. The content of the institutional infrastructure of the car are presented and justified. The analysis condition of the car market’s institutional infrastructure showed the problems associated with the state of institutions which have an impact on the functioning of the car market. Measures to stimulate the car market does not cover entire sector as a whole, and imported institutions do not give the expected effect because of inconsistency formal and informal elements of the institutional infrastructure. Presented assessment of the institutional infrastructure of the car market confirms the dependence of the state of the industry market cars from institutional infrastructure. Only reforming the institutions at all levels of the industry, from production to car sales can have a positive effect on the industry. Changes in the institutional infrastructure should be focused on improving the competitiveness, stability and independence from external factors

  15. Can Sensors Solve the Deterioration Problems of Public Infrastructure?

    Various deteriorations are detected in public infrastructures, such as bridges, viaducts, piers and tunnels and caused fatal accidents in some cases. The possibility of the applications of health monitoring by using sensors is the issues of this lecture. The inspection and diagnosis are essential in the maintenance works which include appropriate rehabilitations and replacements. The introduction of monitoring system may improve accuracy and efficiency of inspection and diagnosis. This seems to be innovation of maintenance, old structures may change smart structures by the installation of nerve network and brain, specifically. Cost- benefit viewpoint is also important point, because of public infrastructures. The modes of deterioration are fatigue, corrosion, and delayed fracture in steel, and carbonization and alkali aggregate reaction in concrete. These are like adult disease in human bodies. The developments of Infrastructures in Japan were concentrated in the 1960th and 1970th. These ages are approaching 50 and deterioration due to aging has been progress gradually. The attacks of earthquakes are also a major issue. Actually, these infrastructures have been supporting economic and social activities in Japan and the deterioration of public infrastructure has become social problems. How to secure the same level of safety and security for all public infrastructures is the challenge we face now. The targets of monitoring are external disturbances such as traffic loads, earthquakes, winds, temperature, responses against external disturbances, and the changes of performances. In the monitoring of infrastructures, 3W1H(WHAT, WHERE, WHEN and HOW) are essential, that is what kind of data are necessary, where sensors place, when data are collected, and how to collect and process data. The required performances of sensors are accuracy, stability for long time. In the case of long term monitoring, the durability of systems needs more than five years, because the interval

    Currently, much of protection planning is conducted separately for each infrastructure and hazard. Limited funding requires a balance of expenditures between terrorism and natural hazards based on potential impacts. This report documents the results of a Laboratory Directed Research & Development (LDRD) project that created a modeling framework for investment planning in interdependent infrastructures focused on multiple hazards, including terrorism. To develop this framework, three modeling elements were integrated: natural hazards, terrorism, and interdependent infrastructures. For natural hazards, a methodology was created for specifying events consistent with regional hazards. For terrorism, we modeled the terrorists actions based on assumptions regarding their knowledge, goals, and target identification strategy. For infrastructures, we focused on predicting post-event performance due to specific terrorist attacks and natural hazard events, tempered by appropriate infrastructure investments. We demonstrate the utility of this framework with various examples, including protection of electric power, roadway, and hospital networks.

    Full Text Available MANETs (Mobile Ad Hoc Networks are slowly integrating into our everyday lives, their most prominent uses are visible in the disaster and war struck areas where physical infrastructure is almost impossible or very hard to build. MANETs like other networks are facing the threat of malicious users and their activities. A number of attacks have been identified but the most severe of them is the wormhole attack which has the ability to succeed even in case of encrypted traffic and secure networks. Once wormhole is launched successfully, the severity increases by the fact that attackers can launch other attacks too. This paper presents a comprehensive algorithm for the detection of exposed as well as hidden wormhole attack while keeping the detection rate to maximum and at the same reducing false alarms. The algorithm does not require any extra hardware, time synchronization or any special type of nodes. The architecture consists of the combination of Routing Table, RTT (Round Trip Time and RSSI (Received Signal Strength Indicator for comprehensive detection of wormhole attack. The proposed technique is robust, light weight, has low resource requirements and provides real-time detection against the wormhole attack. Simulation results show that the algorithm is able to provide a higher detection rate, packet delivery ratio, negligible false alarms and is also better in terms of Ease of Implementation, Detection Accuracy/ Speed and processing overhead.

    Full Text Available The Mobile ad-hoc network (MANET is a collection of wireless mobile node in which each node can communicate with other node without use of predefined infrastructure. Currently, a lot of efficient protocols have been proposed for MANET. All of these efficient Routing protocols are depends only conviction and supportive environment. Conversely, the networks are more vulnerable to various kinds of routing attacks with the presence of malicious nodes. Black hole attack is one of network layer attack. In this attack, A malicious node make use of routing protocol to advertise itself that has a shortest path to reach destination, drops at the cost of original routing packets. In our work, the proposed algorithm is used to secure the DSR protocol. This will help to improve the performance of Mobile Ad hoc network due to the attack. There are several prevention mechanisms to eliminate the Black Hole attack in MANET. The aim of the paper is to provide better prevention of Co-operative Black hole attack in MANET and how it affects the performance metrics in terms of throughput and delay of the network by comparing the network performance with and without black hole nodes.

    Full Text Available A great proportion of essential services are moving into internet space making the threat of DoS attacks even more actual. To estimate the real risk of some kind of denial of service (DoS attack in real world is difficult, but mathematical and software models make this task easier. In this paper we overview the ways of implementing DoS attack models and offer a stochastic model of SYN flooding attack. It allows evaluating the potential threat of SYN flooding attacks, taking into account both the legitimate system flow as well as the possible attack power. At the same time we can assess the effect of such parameters as buffer capacity, open connection storage in the buffer or filte­ring efficiency on the success of different SYN flooding attacks. This model can be used for other type of memory depletion denial of service attacks.Article in Lithuanian

    Beta-endorphin (RIA method, previous chromatographic extraction) was evaluated in plasma of migraine sufferers in free periods and during attacks. Decreased levels of the endogenous opioid peptide were found in plasma sampled during the attacks but not in free periods. Even chronic headache sufferers exhibited significantly lowered levels of beta-endorphin, when compared with control subjects with a negative personal and family history of head pains. The mechanism of the hypoendorphinaemia is unknown: lowered levels of the neuropeptide, which controls nociception, vegetative functions and hedonia, could be important in a syndrome such as migraine, characterized by pain, dysautonomia and anhedonia. The impairment of monoaminergic synapses ("empty neuron" condition) constantly present in sufferers from serious headaches, could be due to the fact that opioid neuropeptides, because of a receptoral or metabolic impairment, poorly modulate the respective monoaminergic neurons, resulting in imbalance of synaptic neurotransmission.

    1999-10-25

    Equipment, materials and methods for the measurement of the biomechanical parameters governing knife stab attacks have been developed and data have been presented that are relevant to the improvement of standards for the testing of stab-resistant materials. A six-camera Vicon motion analysis system was used to measure velocity, and derive energy and momentum during the approach phase of the attack and a specially developed force-measuring knife was used to measure three-dimensional forces and torque during the impact phase. The body segments associated with the knife were modelled as a series of rigid segments: trunk, upper arm, forearm and hand. The velocities of these segments, together with knowledge of the mass distribution from biomechanical tables, allowed the calculation of the individual segment energy and momentum values. The instrumented knife measured four components of load: axial force (along the length of the blade), cutting force (parallel to the breadth of the blade), lateral force (across the blade) and torque (twisting action) using foil strain gauges. Twenty volunteers were asked to stab a target with near maximal effort. Three styles of stab were used: a short thrust forward, a horizontal style sweep around the body and an overhand stab. These styles were chosen based on reported incidents, providing more realistic data than had previously existed. The 95th percentile values for axial force and energy were 1885 N and 69 J, respectively. The ability of current test methods to reproduce the mechanical parameters measured in human stab attacks has been assessed. It was found that current test methods could reproduce the range of energy and force values measured in the human stab attacks, although the simulation was not accurate in some respects. Non-axial force and torque values were also found to be significant in the human tests, but these are not reproduced in the standard mechanical tests.

    Chopra, Shauhrat S; Dillon, Trent; Bilec, Melissa M; Khanna, Vikas

    2016-05-01

    Modern society is increasingly dependent on the stability of a complex system of interdependent infrastructure sectors. It is imperative to build resilience of large-scale infrastructures like metro systems for addressing the threat of natural disasters and man-made attacks in urban areas. Analysis is needed to ensure that these systems are capable of withstanding and containing unexpected perturbations, and develop heuristic strategies for guiding the design of more resilient networks in the future. We present a comprehensive, multi-pronged framework that analyses information on network topology, spatial organization and passenger flow to understand the resilience of the London metro system. Topology of the London metro system is not fault tolerant in terms of maintaining connectivity at the periphery of the network since it does not exhibit small-world properties. The passenger strength distribution follows a power law, suggesting that while the London metro system is robust to random failures, it is vulnerable to disruptions on a few critical stations. The analysis further identifies particular sources of structural and functional vulnerabilities that need to be mitigated for improving the resilience of the London metro network. The insights from our framework provide useful strategies to build resilience for both existing and upcoming metro systems. PMID:27146689
