云计算环境下虚拟机安全管理模型研究

In the cloud computing environment, the more and more virtual machines (VM) are being used by users, the security management of virtual machine is facing the great challenges. In order to solve the problem of cloud computing security in the virtual environment, this paper puts forward a virtual machine security management model based on the virtual machine deployment and dynamic migration, describes a virtual machine security architecture, introduces a virtual machine deployment and scheduling method based on AHP (analytic hierarchy process) , designs a DDoS attack detection method based on CUSUM algorithm, and tests these methods from functions.
