A Game Model for Predicting the Attack Path of APT

As a major threat today, how to defense against APT (advanced persistent attack) effectively becomes a major issue for network security. APT is a combination of past attacks, not a new one. It´s different from any one of previous attacks. Predicting the attack path of APT exactly would be a breakthrough for the future defense in Internet of things. Firstly, the paper proposes classifications of attack and defense for game model from the perspective of game theory. Then, we present the OAPG model, which uses attack path of APT as the attacker´s strategy. Finally, according to the Nash equilibrium, we compute the optimal attack path for the attacker and best-response strategies for the defender.
