Response to Multiple Attack Behaviour Models in Cloud Computing

User behaviour models have been widely used to simulate attack behaviour in the security domain. In this paper, we introduce one perfect rational and three bounded rational behaviour models to simulate attack behaviour of attack-defense game in cloud computing, and then discuss defender's response to attacks. We assume cloud provider as the role of defender is intelligent to collect attack-related information so that it can predict attack behaviour model, thus the attack behaviour model is known to defender, we therefore build a single-objective optimization game model to find the optimal virtual machine (VM) monitoring strategy against attacker. Finally, through numerical analysis, we prove that when the attack behavior model is known, the corresponding single-objective optimization game solution is better than the other three solutions.
