show that the Nash equilibria in security games are interchangeable, thus alleviating the equilibrium selection problem. 5 1. 2 Stackelberg Security Games Stackelberg games were first introduced to model leadership and commitment (von Stackelberg (1934)). The term Stackelberg security games (SSG) was first introduced by Kiekintveld et al. Stackelberg games are natural models for many important applications that involve human interaction, such as oligopolistic markets and security domains. The defender allocates resources Rto protect a set of targets T. Let n = jTj. After Vincent Conitzer and Tuomas Sandholm published the foundational paper on the Stackelberg game applied in the field of security protection in 2006, a large number of applications of the Stackelberg game in various security issues will hopefully improve the intelligent decision-making solutions to complex security problems. Abstractâ Stackelberg security games are represented by a Stackelberg model for multiple defenders and attackers. plication of Stackelberg models in addressing security chal-lenges, also known as Stackelberg security games (SSGs). Google Scholar; b0120 Korzhyk, D., Conitzer, V., & Parr, R. (2011a). [ 12] to describe specializations of a particular type of Stackelberg game for security as discussed below. Security Administration (TSA) is currently evaluating the GUARDS system for use in scheduling airport security op-erations (Pita et al. While most existing work focuses on single-defender settings, there are many real-world scenarios that involve multiple defenders (e.g., multi-national anti-crime actions in international waters, different security agencies patrolling the … While prior re-search has made progress with regards to scalability, many real world Security Games with Arbitrary Schedules A security game is a two-player Stackelberg game played between an attacker and a defender. 3, Christopher Kiekintveld.

Strong Stackelberg equilibrium (SSE) is the standard solution concept of Stackelberg security games. 11/11/17 - Stackelberg Security Games (SSGs) have been adopted widely for modeling adversarial interactions.

Albarran and Clempner 15 developed a solution for Stackelberg security games based in partially observable Markov games. Stackelberg vs. Nash in Security Games: An Extended Investigation of Interchangeability, Equivalence, and Uniqueness Daniel Redelmeier 5 November 2015 Stackelberg Security games are presented in [9], [4]. This interest is driven in part by a number of high-impact deployed security applications [Tambe, 2011]. ing the structure of these security games, the paper shows that the Nash equilibria in security games are interchangeable, thus alle-viating the equilibrium selection problem. Stackelberg Security Games: Looking Beyond a Decade of Success Arunesh Sinha1, Fei Fang2, Bo An3, Christopher Kiekintveld4, Milind Tambe5 1 University of Michigan 2 Carnegie Mellon University 3 Nanyang Technological University 4 University of Texas at El Paso 5 University of Southern California arunesh@umich.edu, feifang@cmu.edu, boan@ntu.edu.sg, cdkiekintveld@utep.edu, tambe@usc.edu 2011). Results are applied to security games between defenders and attackers, where the noncooperative behaviors are well characterized by the features of the learning process in Stackelberg games. Stackelberg Security Games Strong Stackelberg equilibrium (SSE) is the standard solution concept of Stackelberg security games. Firstly, we formulate the interaction between the defender and the attacker as a Stackelberg game. We show that security games exhibit a phase transition at 0:5 for random Stackelberg security game instances, and that this phase transition corresponds to the computationally hardest instances at the d:sratio of 0:5. Instead of taking into account every single pure strategy, this set is represented through the frequency in which each target is Atlanta, GA, USA. In a dynamic context (repeated games), the models need to be reconsidered. A secrecy capacity is maintained with the Stackelberg using the maximum rate of reliable information. There has been significant recent interest in game theoretic approaches to security, with much of the recent research focused on utilizing the leader-follower Stackelberg game model; for example, these games are at the heart of major applications such as the ARMOR program deployed for security at the LAX airport since 2007 and the IRIS program in use by the US Federal Air Marshals (FAMS). Stackelberg Security Games: Looking Beyond a Decade of Success. The dynamics of the game involves defend-. Several facts are mentioned to state the goodness of information security management modeling of financial systems. In these real-world domains, an important challenge facing the security Stackelberg and Cournot equilibria are stable in a static model of just one period. 2017 14th International Conference on Electrical Engineering, Computing Science and Automatic … of security games. Simulation-based methods in multi-step Stackelberg Security Games in the context of homeland security. A defender’s pure strategy is a subset of targets from Classical game equilibrium models, including Stackelberg Equilibrium, assume perfect rationality of the players. A. Abrahamyan 75 discussed. 1, Fei Fang. In order to paint a cohesive picture, we focus on one type of uncertainty: unknown attacker utilities. In Proceedings of the National Conference on Artificial Intelligence (AAAI) (pp. Second, resolving the leader’s dilemma, it shows that under a natural restriction on se-curity games, any Stackelberg strategy is also a Nash equilibrium Stackelberg Security Games (SSGs) have been adopted widely for modeling adversarial interactions, wherein scalability of equi-librium computation is an important research problem. Second, under a natural restriction on security games, any Stackelberg strategy is also a Nash equilibrium strategy; and furthermore, the solution is unique in a class of security games of which ARMOR is a key exemplar. For the realization of the SSG, we propose a new partially observed random walk technique for the randomization in the scheduling of the patrol planning. Trejo et al 2 suggested an approach for developing attacker-defender Stackelberg security games based on Markov games employing The systems deployed are based on fast algorithms for solving large instances of Bayesian Stackelberg games that capture the interaction between security forces and adversaries. Stackelberg Security games in the proposed work correspond to allocating the resources for the multiple patients' body sensor information with high strategy level space. 2. The Stackelberg security game theory has been extensively developed in the Markov games literature. Much of the existing work focuses on single- recent development of models to assist security forces in randomizing their patrols and their deployment in real applications. Additional Key Words and Phrases: No-regret learning, Stackelberg security games 1. 2, Bo An. Security games … Complexity of computing optimal Stackelberg strategies in security resource allocation games. Stackelberg Security Games is provided and its applicability in information security domain is. We present the work through applying Stackelberg security games for outbreak detection in the adversarial environment and study the strategies and utility of both players. Stackelberg Security games on multiple patient information are described as The leader plays first by committing to a mixed strategy. Stackelberg Security Games A generic Stackelberg security game has two players, a de-fender which first decides how to use midentical resources to protect a set of targets T(m<|T|), and an attacker which observes the defender’s strategy before choosing a target to attack. 4, Milind Tambe. Stackelberg security games have received much attention in recent years. Finally, we explore properties of the discussed models empirically in the context of email spam filtering. Stackelberg games were first introduced to model leadership and commitment [ 11]. The leader’s commitment is observed by the follower, who then plays a best response to the leader’s strategy. 22 - Basic Solution Concepts and Algorithms for Stackelberg Security Games By Christopher Kiekintveld , Manish Jain Edited by Ali E.
