Virtual machine online antivirus system based on kvm virtualization platform

Abstract

The invention relates to the field of computer technology, and proposes an online virtual machine antivirus system based on a KVM virtualization platform. Set the security kernel module, security control module and network module, add the function of reading memory in the KVM kernel module, and provide the interface of the security kernel module registration hook; the security kernel module is used to register the hook in the KVM kernel module, and send the security control The module sends out a scan command, accepts the scanning and virus checking results obtained by the security control module, suspends the suspicious process, and handles the suspicious process accordingly; the security control module calls the antivirus engine to scan and check for viruses for all virtual machine processes in the memory of the security control module, and Report the result to the security kernel module; the network module is composed of a server-side network module and a client-side network module.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a virtual machine online antivirus system based on a KVM virtualization platform. Background technique [0002] With the development of the Internet, more and more large enterprises or laboratories tend to use virtualization architecture to save server costs or improve application flexibility. The essence of virtualization is to use many virtual machines to replace the original physical machines for various tasks. figure 1 Indicates the basic structure of virtualization, in which the bottom layer x86 Architecture (x86 structure) is the hardware device of the physical machine, including important processor (CPU), memory (Memory), network adapter (NIC), hard disk (Disk), etc. The second layer is the virtualization layer (Virtualization Layer), which is responsible for virtualizing the physical devices on the physical machine so that each virtual machine can be used. Each virtual...
