A Lightweight Security Isolation Approach for Virtual Machines Deployment

Cloud computing has changed the way of IT services; virtualization technology is the foundation of it, which directly affects the security and reliability of the cloud computing platform. From the point of virtualization technology security, we study to integrate mandatory access control mechanism into virtual machines deployment to control resources available for virtual machines, design and implement a lightweight MAC-based strong isolation and migration approach between virtual machines. Experiments show that our method is effective in isolation and migration, and with less performance overload.
