In this work, we try to model PU, SU and adversary interaction with each other in order to improve primary user emulation attacks detection. Delete Game theory provides a sound mathematical approach to deploy limited security resources to maximize their effectiveness. Computational game theory can help us build decision-aids for such efficient security … Security games in online advertising: Can ads help secure the web? In Proceedings of the Workshop on the Economics of Information Security (WEIS). In this regards, we are working on how to model behaviors of the different entities participating in a security scenario as well as designing the useful defense mechanism for following scenarios. This issue becomes worse for the client who cannot detect whether the service provider is compromised or not. to enhance the system security design or response. The official Social Security information has generally made their eyes glaze over as it takes a fairly complex topic and works hard to make it impenetrable. By applying MTD, defenders are able to modify particular configurations in order to confuse attackers. In each category, we identify security problems, players, and game models. Close this message to accept cookies or find out how to manage your cookie settings. We consider the interaction between the attacks and the defense mechanisms as a game played between the attacker and the defender (system administrator). Game Theory for Security: Past, Present and Future Eckhard P uegel Motivation Security Games Massive 2-Player Complete Information Security Games Strategic Attack-Defence Game Conclusion Security Games I Security games model interaction between players: I attacker(s) I defender(s) I They assume that players are rational and non-cooperative. While the connection between game theory and security has been studied for the last several decades, there has been a fundamental shift in the relationship due to the emergence of computational game theory. We use cookies to distinguish you from other users and to provide you with a better experience on our websites. Our first application, Assistant for Randomized Monitoring Over Routes (ARMOR), successfully deployed game-theoretic algorithms at the Los Angeles International Airport (LAX) in 2007 and has been in use there ever since. Email your librarian or administrator to recommend adding this book to your organisation's collection. The ability of current security solutions to address such attackers has been questioned openly, deception techniques are valuable for monitoring enterprise networks and identifying attack preparation and subsequent exploitation. The model seeks to understand if people make individual choices, or if they will instead coordinate and work together? In other words, the game-theoretic study of security mechanisms can take into account the selfish considerations of individual agents and identify the conditions under which each possible strategy performs best. Moving Target Defense (MTD) is recently defined as one of the game changers in security. Game Theory: Why System Security Is Like Poker, Not Chess Game Theory Is Relevant Both on and off the National Stage. The game theory discussion may be a good way to get to the second level of the discussion regarding the desired goals and claiming strategies to achieve them. Global threats of terrorism, drug-smuggling, and other crimes have led to a significant increase in research on game theory for security. Finally, we compute the optimal time of moves when we use MTD mechanism. All games must make certain assumptions about the players and the playing field. The choice of model is fundamentally a question on participants being coordinated or uncoordinated. 2020 Conference on Decision and Game Theory for Security. Game … We summarize the main results of selected works, such as equilibrium analysis and security mechanism designs. In this such a scenarios, defender uses incomplete information to deceive attacker, in this work we try to model this situation with incomplete game theory and extract optimize behavior for both attacker and defender. Game theory in blockchain technology has a dual role to play i.e. Security mechanisms often require the active contribution of several parties. Although service providers (SPs) aim to secure their infrastructure against threats, it is likely that they face attackers. Game theory provides a mature mathematical foundation for making security decisions in a principled manner. Inward is to apply the principles of the theory to the blockchain protocol. Yet, limited security resources cannot be everywhere all the time, raising a crucial question of how to best utilize them. The Zero Day Game. In comparison with similar approaches, our mechanism can be implemented in a transparent way, such that the changes in IP address would not tear down the ongoing connections. Using game theory, the possible strategic and selfish behaviors of parties in security mechanisms can be captured and analyzed. The conference proceedings will be published by Springer as part of the LNCS series. ‎This book constitutes the refereed proceedings of the 8th International Conference on Decision and Game Theory for Security, GameSec 2017, held in Vienna, Austria, in October 2017. I… It provides a quantitative assessment of security, prediction of security outcomes, and a mechanism design tool that can enable security-by … To overcome limitations of the current cloud computing structure, cooperation of cloud providers and sharing their infrastructures in the form of cloud federations has been introduced as a promising solution. This increase is in part due to the new set of problems our societies face, from terrorism to drugs to crime. Therefore, the available bandwidth for the CR network is reduced. https://bit.ly/2UkxCv0We have brand new Holiday Theory Wear + a FNAF x Theory Wear collaboration! By emerging new services, a single cloud provider(CP) is not capable of serving all users growing requests. Game theory is the study of mathematical models of strategic interaction among rational decision-makers.

Modeling the interaction between service provider and his client in presence of an attacker. Security mechanisms often require the active contribution of several parties. We then define a novel mechanism to implement MTD in IPv6 networks. You’ll have to watch all the way to the end to hear about Game Theory, but don’t worry, it’s all in there. GameSec 2020, the 11th Conference on Decision and Game Theory for Security, will take place at the University of Maryland - College Park, from October 26-30, 2020.. II. Game theory provides a sound mathematical approach for deploying limited security resources to maximize their effectiveness. In recent time the concept of game theory has found application in security at various levels including the cyber world usually called security games. In other words, game theory allows for modeling situations of con ict and for predicting the behavior of participants. Consequently, the attacker cannot find vulnerabilities and leverage on them to launch attacks. Security Magazine Content on 'security game theory' In recent months, I’ve had many different conversations with our customers about how the COVID pandemic has impacted their security operations—from global companies with hundreds of thousands of employees to much smaller organizations with control rooms responsible for local operations and campuses. While used in a number of disciplines, game theory … Game theory provides a sound mathematical approach to deploy limited security resources to maximize their effectiveness. A game … Our approach employs Hash Chain Functions to change IP addresses periodically and in a way that the attacker cannot find the target easily. Adversaries are targeting the communications and information systems (CIS) of government, military and industrial organizations, as well as critical infrastructures, and are willing to spend large amounts of money, time and expertise on reaching their goals. For the past few years, airports have been working with game theorists to step up their security game. In addition, recent sophisticated insider attacks resulted in the exfiltration of highly classified information to the public. Increasing the amount of generated data raises new challenges for processing data in a large scale. A typical approach is to randomize security schedules to avoid predictability, with the randomization using artificial intelligence techniques to take into account the importance of different targets and potential adversary reactions. We have led a wide range of actual deployed applications of game theory for security. Trust of CPs to each other’s and selecting suitable cooperator is one of challenging issues to cloud federation realization. Game Theory : Security games, Applications to security CSC304 - Nisarg Shah 1. Google Scholar Digital Library; Vratonjic, N., Raya, M., Hubaux, J.-P., and Parkes, D. 2010b. To compute the trust of CPs to each other, a dynamic trust function composed of direct trust and indirect trust is proposed. Get our NEW Holiday & Official Theorist x FNAF Merch! Despite the huge benefits of this platform, it faces several challenges, where security issues are the biggest ones. It has applications in all fields of social science, as well as in logic, systems science and computer science.Originally, it addressed zero-sum games, in which each participant's gains or losses are exactly balanced by those of the other participants. My research group has been at the forefront of this effort to apply computational game theory techniques to security problems. Apparently thousands of viewers watch the “Theory of Bitcoin” videos but only about 250 watch all the way to the end. A typical approach is to randomize security schedules to avoid predictability, with the randomization using artificial intelligence techniques to take into account the importance of different targets and potential adversary reactions. In this regard, forming the stable coalitions in the form of trusted cloud federations by using the cooperative game theory was our main focus. Moreover, the routers between sender and receiver cannot obtain enough information about the current IP address of the sender that uses our protocol. In the arena of security, where game theory has always been popular, there now seems to be an exponential increase in interest. Security games help formalizing security problems and decisions using quantitative models. Game theory provides a sound mathematical approach for deploying limited security resources to maximize their effectiveness. RELATED WORK Security under a game theoretic framework is an interesting topic, where several probable actions along with the predicted outcome can be suggested through game theoretic methods in order to control future threats. In addition, we provide a discussion on the advantages, drawbacks, and … In Proceedings of the Conference on Decision and Game Theory for Security (GameSec). Game theory, the study of strategic decision-making, brings together disparate disciplines such as mathematics, psychology, and philosophy. Game theory offers a natural frameworkfor capturing the defensive as well as adversarial interactions between the defenders and the attackers.Furthermore, defenders can attain a deep understanding of the potential attack threats and the strategiesof attackers by equilibrium evaluation of the security games. Our framework helps designers to find the optimal strategy to be employed with MTD, given any new type of attacks. Game theory provides a natural framework to capture the adversarial and defensive interactions between an attacker and a defender. How to Utilize Game Theory for Security Awareness ... That’s not to say that enterprises should start asking employees to play video games at work in the name of security – it’s applying different techniques that make games particularly successful and memorable to an education program and business objectives, Sedova says. In this work, we first propose a framework to analyze MTD advantages and drawbacks in any given system, considering the attack surface. This trend is accelerated with the introduction of Cloud Computing. Imagine you found a new zero-day vulnerability. In daily life there are clearly cases where both exist, and this holds true in cryptoeconomics.

In other words, the game-theoretic study of security mechanisms can take into account the selfish considerations of individual agents and identify the conditions under which These problems are ubiquitous. While the connection between game theory and security has been studied for the last several decades, there has been a fundamental shift in the relationship due to the emergence of computational game theory. Based on the proposed method of our research, CPs are capable of analyzing their cooperators and refuse to cooperate with malicious CP. network attacks to demonstrate how the proposed game theory can be applied in a broad range of cybersecurity problems. Game theory's popularity continues to increase in a whole variety of disciplines, including economics, biology, political science, computer science, electrical engineering, business, law, and public policy. Game theory provides a sound mathematical approach to deploy limited security resources to maximize their effectiveness. In game theory, we rely on assuming a model of human interaction and of each player’s utility function (what they value). Increasing applications of hardware and software infrastructures have led to the notable development of cloud computing technology. In this path-breaking theoretical work, political scientist Steven Brams and mathematician Mark Kilgour show how game theory can be applied to the rigorous development and thoughtful analysis of several critical problems that afflict the security of nations, from the deterrence of foes who might launch attacks, to the stabilization of crises that could explode into wars. Recap ... Stackelberg game is always greater than or equal to his maximum reward under any Nash equilibrium of the simultaneous-move version. The 24 revised full papers presented together with 4 short papers were carefully reviewed and selected from 7… Security Games Simple security game with multiple targets Defender allocate resources to protect out of targets Attacker choose a target to attack If attack on target succeeds ( unprotected): Defender get Attacker get If attack on target fails ( protected) Defender get (≥ ) GAO United States Government Accountability Office Federal Air Marshal Service Has Taken Actions to Fulfill Its Core Mission and Address Workforce Issues, but Additional Actions Are Needed to Improve Workforce Survey, http://www.gao.gov/highlights/d09273high.pdf, A generalized Nash solution for two-person bargaining games with incomplete information, Security Games with Arbitrary Schedules: A Branch and Price Approach, Proceedings of Association for Advancement of Artificial Intelligence (AAAI), A Double Oracle Algorithm for Zero-Sum Security Games on Graphs, Quality-bounded Solutions for Finite Bayesian Stackelberg Games: Scaling up, Computing Optimal Randomized Resource Allocations for Massive Security Games, Approximation Methods for Infinite Bayesian Stackelberg Games: Modeling Distributional Uncertainty, Proceedings of the International Conference on Autonomous Agents and Multiagent Systems (AAMAS), Complexity of computing optimal Stackelberg strategies in security resource allocation games, National Conference on Artificial Intelligence (AAAI), An Efficient Heuristic Approach for Security Against Multiple Adversaries, Coordinating randomized policies for increasing security of agent systems, Journal of Information Technology and Management (ITM), Deployed ARMOR protection: The application of game theoretic model for security at the Los Angeles International Airport, Efficient solutions for real-world Stackelberg games, GUARDS – Game Theoretic Security Allocation on a National Scale, Defending against terrorist attacks with limited resources, IRIS – a tool for strategic security application in transportation networks, Urban Security: Game-Theoretic Resource Allocation in Networked Physical Domains, Transiting areas patrolled by a mobile adversary, Generation of Random Sequences by Human Subjects: A Critical Survey of Literature, Stackelberg vs. Nash in Security Games: Interchangeability, Equivalence, and Uniqueness. Personal responsibility, religion, and Bitcoin’s Game Theory. More specifically, with the development of new computational approaches to game theory over the past two decades, very large-scale problems can be cast in game-theoretic contexts, thus providing us computational tools to address problems of security allocations. Game theory is the process of modeling the strategic interaction between two or more players in a situation containing set rules and outcomes. The number and complexity of cyber-attacks have been increasing steadily in the last years. In one hand, we can model the interaction between the service provider and the attacker as a non-cooperative normal form game. The idea of outsourcing computational jobs is proposed to overcome the complexity and cost for applications that rely on big data processing. Prior work has considered models ranging from two-player games to n-player games, with the players representing various combinations of defenders and attackers. Game Theory and Cybersecurity Game theory is a theoretical framework used to observe interactions between opposing forces. Game theory provides mathematical tools and models for investigating multi-person strategic decision making where the players or DMs compete for limited and shared resources. 1. We elaborate on FlipIt protocol (i.e., a defined game of stealthy takeover), considering the probability of successful attack/defense and show how these parameters can change the time of defense with MTD. Moreover, QoS factors of cloud services is considered in the computation of the trust function. As all of these entities are rational decision makers, game theory can help us for modeling their interactions to guide the client how reacts in this system, in presence of the underlying uncertainty about the type of the service provider. Outward is to integrate the strategic decision-making model with the business’ process. We believe that our results would be the first step towards designing an efficient MTD protocol in computer networking. Using game theory, the possible strategic and selfish behaviors of parties in security mechanisms can be captured and analyzed. Game theory for security has grown to be a diverse area of research. On the other hand, as the client faces an uncertainty and should decide to either rely on the received service from the SP or not, we can model the interaction between the client and the SP as a signaling game. Moreover, in Cognitive Radio (CR), if a CR network is exposed to an intelligent adversary, it can put spoofing signals into those bands that are available for secondary users (SU), so that the secondary users are deceived into believing that these bands are occupied by primary users (PU) and should not be accessed.
