Intrusion Detection has a central role in every organization’s IT Security. However, limitations and problems prevent the commercial spread of Intrusion Detection Systems. This paper presents an attempt to improve Intrusion Detection benefits with the use of Game Theory. A generic intrusion detection game model that reveals the way an IDS interacts with a user is described and examined thoroughly. Moreover, a specific scenario with an internal attacker and an IDS is presented in a normal form game to validate the functioning of the proposed model. Solutions for this game are given as a one shot game as well as an infinitely repeated game.
