Abstract:

With the rapid development of cloud computing technology, the event of cloud security has an increasing trend in linear, which has become a serious issue to be solved in the cloud computing. Virtualization technology is the key of cloud computing. It can effectively promote the development and application of cloud computing to enhance the security of the virtualization platform. In the virtualization platform, the traditional security solutions cannot keep it safe. At first, this paper introduced the virtualization technology and the major virtualization platforms, and analyzed the various security issues faced by the current virtualization platform and its preventive methods. Then through the comparative analysis of the number and types of security vulnerability in traditional environment, virtualization platform, the research concern and other aspects, the paper proposed the current security situation and development trend of security threat of the virtualization platform. Finally, this paper summarized the main problems of the virtualization platform and provided countermeasures.

Key words: cloud computing, cloud security, virtualization technology, security vulnerability, virtualization platform
