基于角色的云环境下虚拟机安全访问控制策略

Virtual Machine Security Access Control Strategy in Role-based Cloud Environment

云计算凭借灵活、高效的特性为现代社会发展提供重要支持,但同时伴随出现较多安全性问题,因此研究云环境下虚拟机的安全技术是十分必要的。首先对云计算技术层面进行分析,其次介绍虚拟化存在的自身安全威胁与虚拟机安全威胁,最后提出基于角色的云环境下虚拟机安全访问控制策略。该策略通过将角色进行隔离访问,对用户信任证书与信任等级综合验证,完成对云计算平台中数据储存、隔离和访问的保护,为云计算安全技术提供借鉴。

The flexible and efficient characteristics of cloud computing provides important support for the development of modern society.At the same time,there are many security problems.Therefore,it is necessary to study the security technology of virtual machine in cloud environment.This paper first analyzes the technical level of cloud computing,then introduces the self security threats and virtual machine security threats of virtualization,and finally puts forward the virtual machine security access control strategy in role-based cloud environment.Through the isolated access of roles,the user trust certificate and trust level are comprehensively verified to complete the protection of data storage,isolation and access in the cloud computing platform,so as to provide reference for cloud computing security technology.
