云环境下面向拟态防御的反馈控制方法

云环境下的虚拟化技术,给用户带来了一些数据和隐私安全问题.针对云环境中虚拟机单一性、同质性和静态性等问题,文章提出一种云环境下面向拟态防御的反馈控制方法.该方法以云中虚拟机为基础,利用拟态防御技术对虚拟机进行拟态化封装,通过反馈控制架构对其实现闭环负反馈控制,并基于异构虚拟机动态轮换改变执行环境,保证虚拟机系统环境的随...

Feedback Control Method for Mimic Defense in Cloud Environment

The virtualization technology in the cloud environment brings some data and privacy security issues to users.Aiming at the problems of the singleness,homogeneity and static stateof virtual machines in the cloud environment,a feedback control method for mimic defense under the cloud environment is proposed.This method is based on the virtual machine in the cloud and uses mimic defense technology to mimic encapsulation of virtual machines,through the feedback control architecture to achieve closed-loop negative feedback control,and based on the dynamic rotation of heterogeneous virtual machines to change the execution environment to ensure the randomness of the virtual machine system environment.Experiments show that the design achieves error tolerance for user services,suspicious virtual machine detection and dynamic rotation,which increases the difficulty for attackers to exploit vulnerabilities.
