Threat intelligence response and disposal method and system based on virtual machine introspection

Abstract

The invention relates to a threat intelligence response and disposal method and system based on virtual machine introspection. A threat detection and response module is deployed on a privilege virtualmachine except a detected virtual machine; a virtual machine introspection technology is used for obtaining a port number-transmission layer network protocol-process corresponding relationship in thedetected virtual machine which carries out network communication; the network data package of virtual machine communication is captured and analyzed; a network threat intelligence database is used for judging whether the data package has threats or not; and if the data package has threats, a thread alarm is given, and the obtained corresponding relationship is used for positioning and threateningthe virtual machine process of thread source communication so as to block the process or the port and the like. By use of the method and the system, the threat detection and response module is deployed on the outer part of the detected virtual machine, the detection and response module is effectively protected, meanwhile, process-level network threat detection and response can be finished, existing cloud architecture does not need to be changed, and the method and the system can be conveniently applied to a server of a cloud service provider.

Description

technical field [0001] The invention belongs to the field of information technology, in particular to a threat intelligence response and processing method and system based on virtual machine introspection. Background technique [0002] With the rapid development of cloud computing, there are more and more network attacks against enterprise server virtual machines, which have brought huge losses to cloud computing service providers and users. In order to detect and respond to network threats and reduce the harm caused by network attacks, there are two commonly used methods at this stage: installing security protection software in virtual machines; deploying security protection software on LANs. These methods maintain the security of the virtual machine system to a certain extent, but they are not perfect, mainly in the following aspects: [0003] (1) Install the security protection software in the virtual machine, and install the software and configure the security policy fo...

AI Technical Summary

Problems solved by technology

[0003] (1) Install the security protection software in the virtual machine, and install the software and configure the security policy for each virtual machine, and the maintenance cost is high;

[0004] (2) Install the security protection software in the virtual machine, because it runs in the system to be protected, the security software may be attacked, and the security is poor;

[0005] (3) When the security protection software is deployed on the LAN, only threat information at the operating system level can be obtained, and the protection efficiency is poor
