This paper presents a game-theoretic method for analyzing the active defense of computer networks. We regard the interactions between an attacker and the defender as a two-player, non-cooperative, zero-sum, finite game and formulate an attack-defense game (ADG) model for the game. An optimal active defense strategy decision (OADSD) algorithm is developed(More)
For assessing the security and optimal strengthening of large enterprise networks, this paper proposes a new approach uses configuration information on firewalls and vulnerability information on all network devices to build defense graphs that show the attack and defense strategy. Some models including a defense graph model, attack-defense taxonomy and cost(More)
