Abstract:

The virtualization technology in the cloud environment brings some data and privacy security issues to users. Aiming at the problems of the singleness, homogeneity and static stateof virtual machines in the cloud environment, a feedback control method for mimic defense under the cloud environment is proposed. This method is based on the virtual machine in the cloud and uses mimic defense technology to mimic encapsulation of virtual machines, through the feedback control architecture to achieve closed-loop negative feedback control, and based on the dynamic rotation of heterogeneous virtual machines to change the execution environment to ensure the randomness of the virtual machine system environment. Experiments show that the design achieves error tolerance for user services, suspicious virtual machine detection and dynamic rotation, which increases the difficulty for attackers to exploit vulnerabilities.

Key words: cloud environment, mimic defense, feedback control, dynamic rotation
