Embodiment Construction
[0045] In order to make the purpose, technical solution and advantages of the present invention clearer, the security protection method and device based on the virtualization environment of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0046] The security protection method based on the virtualization environment provided by the embodiment of the present invention can be applied to figure 1 In the security protection system shown, the security protection system runs on a physical host. The physical host includes a processor connected through a system bus, a non-volatile storage medium, memory, a network interface, a display screen and an input system. Multiple customer virtual machines and security virtual machines are deployed on the physical h...

The invention provides a security protection method and device based on a virtualized environment. The method comprises the steps that a security virtual machine receives an active scanning task and sends a security protection instruction to a guest virtual machine specified by the active scanning task; the security virtual machine receives a file event processing request, responding to the security protection instruction, of the guest virtual machine; the security virtual machine acquires a CPU usage rate of a security processing procedure; the security virtual machine compares the CPU usage rate with a preset CPU usage rate threshold value of the security processing procedure; if the CPU usage rate is higher than the preset CPU usage rate threshold value, the security virtual machine refuses to process a file event in the file event processing request. According to the security protection method and device, by limiting the CPU usage rate of the active scanning process in the security virtual machine, the security virtual machine can quickly respond to the file event of file monitoring in the guest virtual machine, and then the operation speed of the guest virtual machine is increased.
Description
technical field [0001] The invention relates to the technical field of virtualization, in particular to a security protection method and device based on a virtualization environment. Background technique [0002] With the widespread application of hardware virtualization technology, multiple operating systems can run simultaneously on a physical host, and the operating systems are isolated from each other, making the management of hardware facilities more effective, flexible and economical. However, there are security threats faced in the deployment of operating systems based on virtualization technology. [0003] In order to solve the problem of virtual machine security in a virtualized environment, the traditional solution needs to deploy a set of security protection software in each virtual machine on each physical host, so as to achieve the same security protection software installed in the operating system on a common physical machine. same function. [0004] However,...
