Cloud computing risk assessment method based on game theory

As a product of the development of the Internet, security issues of cloud computing has attracted much attention whether it is from the cloud providers´ point of view or from the perspective of cloud users. From the view of information security, risk assessment model is established in this paper using game theory, which involves the damage and the restore of the cloud system. Using the framework, the interaction between attacker and defender has been analysed and risk assessment of vulnerable points in cloud environment is conducted.
