云计算环境下虚拟化安全探讨

通过对IT的各类资源进行池化，并以服务的形式提供或交付给用户，云计算模式在技术和成本上都具有较大的优势，获得了广泛的认可。虚拟化技术是实现云计算的基础，可以将IT资源逻辑抽象并形成资源池，提高了资源利用率。然而，虚拟化给传统的安全目标实现带来新的挑战。文章首先分析了云计算环境下虚拟化面临的安全风险，研究了当前针对虚拟化安全风险的技术及方案，最后指出虚拟化安全存在的问题及进一步工作。

Study of Virtualization Security in Cloud Computing

With the pattern that pooling the IT resources and providing IT resource as service to customs, cloud computing has good advantages in technology and cost and has been widely approved. As a foundation of cloud computing, the virtualization technology enables IT resources to be logical resources and pools them in order to improve the resource utilization rate. However, the traditional security of IT system with virtualization is also facing new challenges. This paper analyzes the virtualization security risks of cloud computing in detail, discusses the related technologies and solutions for the virtualization security, and points out the existing problems and looks forward to the further works.
