云计算数据中心安全防护技术研究

Security protection of cloud data center

随着云计算技术的大规模应用,敏感信息和数据泄漏越发普遍,传统的网络信息安全技术遭到云模式架构的挑战,诸如云计算平台自身安全问题、云计算平台的运行安全评测和监管问题、云计算机平台的安全保障问题等越来越突出.针对云计算应用虚拟化、边界模糊、多用户等特性进行分析,对基于VMware EXS虚拟化平台下可信计算基的构建技术进行研究,为运行于其上的虚拟应用服务主机构建相互独立的可信计算基从而构建新的数据安全策略和信息安全保障体系,以实现对云计算应用平台的安全保护.

The applications of cloud computing are becoming a trend,and sensitive information and data leakages are a common problem.Traditional network information security technologies are challenged by the cloud model architecture,such as cloud computing platform operational security assessment and regulatory issues,and cloud computer platform security issues become more and more outstanding.This paper analyzes the characteristics of virtualization,fuzzy boundaries and multi-users of cloud computing,researches the building technology of trusted computing base which is based on VMware EXS virtualization platform.In order to achieve the security of cloud computing application platform,a new data security strategy and information security system are built through building independent trusted computing base of virtual application service host.
