Research on APT attack based on game model

摘要

Considering the lack of theoretical analysis for distributed network under APT (advanced persistent threat) attacks, a game model was proposed to solve the problem based on APT attack path. Firstly, this paper analyzed the attack paths of attackers and proposed the defensive framework of network security by analyzing the characteristics of the APT attack and the distributed network structure. Secondly, OAPG(an attack path prediction model oriented to APT) was established from the value both the attacker and the defender based on game theory, besides, this paper calculated the game equilibrium and generated the maximum revenue path of the attacker, and then put forward the best defensive strategy for defender. Finally, this paper validated the model by an instance of APT attack, the calculated results showed that the model can analyze the attacker and defender from the attack path, and can provide a reasonable defense scheme for organizations that use distributed networks.
