Wireless Sensor Networks (WSNs) are becoming an integral part of our lives. There are not widespread applications of WSNs without ensuring WSNs security. Due to the limited capabilities of sensor nodes in terms of computation, communication, and energy, providing security to WSNs is challenging. In fact, the process of implementing WSNs security is adaptive and dynamic, which evolves continuall...

In the last years, there has been a substantial effort in the application of Stackelberg game-theoretic approaches in the security arena, in which security agencies implement patrols and checkpoints to protect targets from criminal attacks. The classical game-theoretic approach employed successful to solve security games is that of a Stackelberg game between a defender (leader) and an attacker ...

Game theory has been used to model several areas of information security like network security, intrusion detection, information warfare and security investment. We first survey the game theoretical approaches in these areas of information security. We then explore the role of game theory in modeling an area of information security the strategic interaction between malware writers and antimalwa...

Games have a long tradition in teaching IT security: Ranging from international capture-the-flag competitions played by multiple teams to educational simulation games where individual students can get a feeling for the effects of security decisions. All these games have in common, that the game’s main goal is keeping up the security. In this paper, we propose another kind of educational securit...

There has been a growing interest in decision and game theoretic approaches to networked system security as evidenced by the increasing number of publications and conferences such as the Conference on Decision and Game Theory for Security (GameSec). This presentation aims to give an overview on security games and their applications to network and critical infrastructure security based on the re...

Computational game theory has become a powerful tool to address critical issues in security and sustainability. Casting the security resource allocation problem as a Stackelberg game, novel algorithms have been developed to provide randomized security resource allocations. These algorithms have led to deployed security-game based decision aids for many real-world security domains including infr...

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. In the arena of security, where game theory has always been popular, there now seems to be an exponential increase in interest. This increase is in part due to the new set of problems our so...

When investing in cyber security resources, information security managers have to follow effective decision-making strategies. We refer to this as the cyber security investment challenge. In this paper, we consider three possible decision-support methodologies for security managers to tackle this challenge. We consider methods based on game theory, combinatorial optimisation and a hybrid of the...
