Abstract

The invention discloses a host safeguarding method and device and belongs to the technical field of virtualization; the host safeguard method comprises: acquiring information of virtualization software, issuing a safeguard strategy, monitoring access actions of a virtual machine, intercepting illegal actions, and other steps. The access actions of the virtual machine are correlated to the type and version of virtualization software, whether the actions are secure or not is judged by monitoring the actions of the virtual machine, and unsecure actions are intercepted in time; the host safeguarding method and device have the advantages of good logic simplicity, ease of implementation and good result reliability, comprehensive safeguarding can be provided for a host and virtualization software without changing existing Hypervisor code, and the host safeguarding method and device are a new path compared to the prior art and belong to a major modification to the prior art.

Description

technical field [0001] The present invention relates to the technical field of virtualization, in particular to a host machine security protection method and device. Background technique [0002] Virtualization technology can virtualize one computer into multiple logical computers, so that multiple logical computers can run on one physical computer at the same time, each logical computer can run a different operating system, and applications can run on each other. Run in an independent space without affecting each other, thereby significantly improving the work efficiency of the computer. Virtualization technology uses software to re-divide computing resources, which can realize dynamic allocation, flexible scheduling, and cross-domain sharing of computing resources, improve the utilization rate of computing resources, and enable computing resources to truly become social infrastructure and serve flexible services in all walks of life. Changing application requirements. ...
