应用于云计算中心的虚拟主机安全防护系统

针对云计算环境下的安全防护问题，文中提出了一种云计算中心虚拟主机安全防护系统。系统以“安全即服务冶为出发点，以虚拟机为核心，针对虚拟化计算无边界的特点，以虚拟机群为单位，提供统一的安全防护。为云平台下的不同应用、租户、虚拟主机提供定制化的安全服务，以安全防护模板的形式对不同的安全性需求进行量身定制，将安全防护措施软件化、安全功能组件化、部署方式动态化、配置管理自动化，使安全处置手段不断更新，从而建立起了集各种安全措施为一体的自适应云平台安全防护体系。

A Virtual Host Protection System Applying to Cloud Computing Center

A virtual host protection system applying to cloud computing center is constructed in this paper to guarantee the security of cloud computing. Virtualization calculation has the characteristics of being no boundary. According to this,the virtual host protection sys-tem provides a unified security for cloud computing by taking security-as-a-service as a starting point,the virtual machine as the core, and the virtual cluster as a unit. Customized security services are provided for different applications,multi-tenancy,and virtual hosts on the cloud computing platform. The security template is tailored to satisfy the different security needs. The security protection measures are realized by software,the security function is achieved by components,the deployment method becomes dynamic,the configuration man-agement becomes automatic,and the security disposal means are updated constantly. Then the adaptive security protection system integra-ting with a variety of security measures for cloud computing platform is built.
