Enhancing the network security using lexicographic game

Abstract

This paper presents a new modeling method to enhance the network security using game theory. Reconnaissance is applied as a game strategy to obtain more information about the enemy's strategic intentions.Indefinite Event Nets method is used to model the framework and analyze to defend the network attacks. The game issues are solved with the help of Indefinite Key Nets. The course of action for a player in multi-player game environment is also determined. Finally, the Nash equilibrium is computed and best-response strategies for the players (administrator and attacker) are found. It proves how the strategies are realistic and how the administrators can use these results to enhance the security of their network. © 2012 ICST Institute for Computer Science, Social Informatics and Telecommunications Engineering.
