In other words, game theory allows for modeling situations of con ict and for predicting the behavior of participants. Finally, we compute the optimal time of moves when we use MTD mechanism. 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. Yet, limited security resources cannot be everywhere all the time, raising a crucial question of how to best utilize them. https://bit.ly/2UkxCv0We have brand new Holiday Theory Wear + a FNAF x Theory Wear collaboration! 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.. 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. In the arena of security, where game theory has always been popular, there now seems to be an exponential increase in interest. I… 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. 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. Increasing the amount of generated data raises new challenges for processing data in a large scale. Game theory for security has grown to be a diverse area of research. In this work, we try to model PU, SU and adversary interaction with each other in order to improve primary user emulation attacks detection. The model seeks to understand if people make individual choices, or if they will instead coordinate and work together? Inward is to apply the principles of the theory to the blockchain protocol.

All games must make certain assumptions about the players and the playing field. Game theory provides a sound mathematical approach for deploying limited security resources to maximize their effectiveness. 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. 2020 Conference on Decision and Game Theory for Security. While used in a number of disciplines, game theory … In recent time the concept of game theory has found application in security at various levels including the cyber world usually called security games. 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. Using game theory, the possible strategic and selfish behaviors of parties in security mechanisms can be captured and analyzed. Our approach employs Hash Chain Functions to change IP addresses periodically and in a way that the attacker cannot find the target easily. 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. My research group has been at the forefront of this effort to apply computational game theory techniques to security problems. II. Outward is to integrate the strategic decision-making model with the business’ process. 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. Trust of CPs to each other’s and selecting suitable cooperator is one of challenging issues to cloud federation realization. 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. By applying MTD, defenders are able to modify particular configurations in order to confuse attackers. These problems are ubiquitous. Game theory provides a sound mathematical approach for deploying limited security resources to maximize their effectiveness. Game … Google Scholar Digital Library; Vratonjic, N., Raya, M., Hubaux, J.-P., and Parkes, D. 2010b. For the past few years, airports have been working with game theorists to step up their security game. 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. By emerging new services, a single cloud provider(CP) is not capable of serving all users growing requests. 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. 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. Email your librarian or administrator to recommend adding this book to your organisation's collection. Moreover, QoS factors of cloud services is considered in the computation of the trust function. Modeling the interaction between service provider and his client in presence of an attacker. Despite the huge benefits of this platform, it faces several challenges, where security issues are the biggest ones. Increasing applications of hardware and software infrastructures have led to the notable development of cloud computing technology. 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. inward & outward. 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. We summarize the main results of selected works, such as equilibrium analysis and security mechanism designs. In one hand, we can model the interaction between the service provider and the attacker as a non-cooperative normal form game. Delete We use cookies to distinguish you from other users and to provide you with a better experience on our websites. This trend is accelerated with the introduction of Cloud Computing. Game theory, the study of strategic decision-making, brings together disparate disciplines such as mathematics, psychology, and philosophy. 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. 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. Game theory provides a natural framework to capture the adversarial and defensive interactions between an attacker and a defender. This increase is in part due to the new set of problems our societies face, from terrorism to drugs to crime. The number and complexity of cyber-attacks have been increasing steadily in the last years. 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. 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 The 24 revised full papers presented together with 4 short papers were carefully reviewed and selected from 7… The choice of model is fundamentally a question on participants being coordinated or uncoordinated. In addition, we provide a discussion on the advantages, drawbacks, and … Game Theory: Why System Security Is Like Poker, Not Chess Game Theory Is Relevant Both on and off the National Stage. 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. The conference proceedings will be published by Springer as part of the LNCS series. Game theory provides a sound mathematical approach to deploy limited security resources to maximize their effectiveness. ‎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. In this work, we first propose a framework to analyze MTD advantages and drawbacks in any given system, considering the attack surface. 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. Game Theory and Cybersecurity Game theory is a theoretical framework used to observe interactions between opposing forces. Game theory is the process of modeling the strategic interaction between two or more players in a situation containing set rules and outcomes.

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. 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. We then define a novel mechanism to implement MTD in IPv6 networks. 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. It provides a quantitative assessment of security, prediction of security outcomes, and a mechanism design tool that can enable security-by … Although service providers (SPs) aim to secure their infrastructure against threats, it is likely that they face attackers. We believe that our results would be the first step towards designing an efficient MTD protocol in computer networking. Game Theory : Security games, Applications to security CSC304 - Nisarg Shah 1. Recap ... Stackelberg game is always greater than or equal to his maximum reward under any Nash equilibrium of the simultaneous-move version. 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. Security mechanisms often require the active contribution of several parties. Security games in online advertising: Can ads help secure the web? In Proceedings of the Workshop on the Economics of Information Security (WEIS). 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 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. The Zero Day Game. In addition, recent sophisticated insider attacks resulted in the exfiltration of highly classified information to the public. Guirguis discussed how game theory techniques can be applied to many cybersecurity problems. Imagine you found a new zero-day vulnerability. Moreover, the routers between sender and receiver cannot obtain enough information about the current IP address of the sender that uses our protocol. In game theory, we rely on assuming a model of human interaction and of each player’s utility function (what they value). Game theory provides a sound mathematical approach to deploy limited security resources to maximize their effectiveness. This issue becomes worse for the client who cannot detect whether the service provider is compromised or not. Game theory provides a mature mathematical foundation for making security decisions in a principled manner. Global threats of terrorism, drug-smuggling, and other crimes have led to a significant increase in research on game theory for security. Prior work has considered models ranging from two-player games to n-player games, with the players representing various combinations of defenders and attackers. Therefore, the available bandwidth for the CR network is reduced. Personal responsibility, religion, and Bitcoin’s Game Theory. Security games help formalizing security problems and decisions using quantitative models. Security mechanisms often require the active contribution of several parties. Moving Target Defense (MTD) is recently defined as one of the game changers in security. We have led a wide range of actual deployed applications of game theory for security. 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. Using game theory, the possible strategic and selfish behaviors of parties in security mechanisms can be captured and analyzed. In Proceedings of the Conference on Decision and Game Theory for Security (GameSec). 1. Get our NEW Holiday & Official Theorist x FNAF Merch! network attacks to demonstrate how the proposed game theory can be applied in a broad range of cybersecurity problems. Based on the proposed method of our research, CPs are capable of analyzing their cooperators and refuse to cooperate with malicious CP. The idea of outsourcing computational jobs is proposed to overcome the complexity and cost for applications that rely on big data processing. 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. A game … Close this message to accept cookies or find out how to manage your cookie settings. In daily life there are clearly cases where both exist, and this holds true in cryptoeconomics. Game theory in blockchain technology has a dual role to play i.e. Computational game theory can help us build decision-aids for such efficient security … To compute the trust of CPs to each other, a dynamic trust function composed of direct trust and indirect trust is proposed. Game theory provides a sound mathematical approach to deploy limited security resources to maximize their effectiveness. 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 consider the interaction between the attacks and the defense mechanisms as a game played between the attacker and the defender (system administrator). In this regard, forming the stable coalitions in the form of trusted cloud federations by using the cooperative game theory was our main focus. Google Scholar Our framework helps designers to find the optimal strategy to be employed with MTD, given any new type of attacks.

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. Apparently thousands of viewers watch the “Theory of Bitcoin” videos but only about 250 watch all the way to the end. Consequently, the attacker cannot find vulnerabilities and leverage on them to launch attacks. In each category, we identify security problems, players, and game models. to enhance the system security design or response. Game theory is the study of mathematical models of strategic interaction among rational decision-makers.
