Because of its advantages in efficiency,cost,scalability,virtualization technology is widely applied in recent years in the field of cloud computing. However,virtualization also brings some negative effects in terms of security,including that virtualization adds the technical layer,and there must be additional security controls,thus raising the burden of security management; Virtualized environment is highly dynamic,thus makes creation and maintenance of the necessary security border more complex. When security vulnerabilities occur,many virtual systems concentrated on a single physical computer architecture might cause fairly great impact. This article,from the aspects of technology,management,operation and maintenance,discusses the virtualized security.
