随着“云计算”技术应用的发展,数字档案的应用得到了技术保证,为云计算数据中心的建设提供了技术支持。而如何保障云中数据的安全成为云计算数据中心需解决的关键问题之一。本文从物理安全、应用系统安全、虚拟化安全、网络安全等四方面搭建了云计算数据中心安全框架,为保障云中数据安全提供完整的技术方案。 With the development of “cloud computing” technology application, the application of digital archives has been guaranteed by technology and has provided technical support for the construction of cloud computing data center. How to protect the security of cloud data has become one of the key issues to be solved in cloud computing data center. In this paper, a cloud computing data center security framework is built from four aspects: physical security, application system security, virtualization security, and network security, and provides a complete technical solution for data security in the cloud.
