Virtualization security for cloud computing service

Virtualization is a term that refers to the abstraction of computer resources. The purpose of virtual computing environment is to improve resource utilization by providing a unified integrated operating platform for users and applications based on aggregation of heterogeneous and autonomous resources. More recently, virtualization at all levels (system storage, and network) became important again as a way to improve system security, reliability and availability, reduce costs and provide greater flexibility. In this paper, we address the requirements and solutions for the security of virtualization in cloud computing environment. Moreover, a Virtualization Security framework is presented which contains two parts: virtual system security and virtualization security management.
