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)
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)
