Design of basic process of information security risk assessment in cloud computing environment

in the risk assessment of cloud computing, how to quantify the risk probability is one of the most important problems. Generally speaking, people can only make use of conjecture, quantitative information and so on. But the risk probability obtained by this way is often different from the actual probability. In this paper, by constructing the attack and defense game model of malicious attacker and defender in cloud computing, the interactive game process of attack and defense is analyzed. Cloud computing system can predict the behavior of attack, get scientific quantitative risk probability, and then realize the risk assessment process of cloud computing system.
