Embodiment Construction

[0036] In order to make the object, technical solution and advantages of the present invention clearer, the implementation manner of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0037] The virtual machine dynamic migration security framework of this embodiment is composed of a centralized control engine and local migration engines located on independent servers.

[0038] The centralized control engine grasps the usage of physical and virtual resources in the platform as a whole, and under the control of the security migration strategy, initiates virtual machine dynamic migration operations on demand to achieve load balancing within the platform.

[0039] The centralized control engine consists of six parts: security migration policy, identity authentication, access control, security audit, hotspot detection, and security migration management.

[0040] (1) Security Migration Policy: Manage and formulate securit...

Abstract

The invention provides a security framework and relates to the technical field of computer information security, in particular to a dynamic migration security framework of a virtual machine. The dynamic migration security framework is composed of a centralized control engine and a local migration engine; the centralized control engine provides functions of two-way authentication, access control and security audit under the control of a security policy, monitors resource utilization of a physical server and the virtual machine in real time, and provides resource basis for dynamic migration of the virtual machine. The local migration engine completes the dynamic migration of the virtual machine in stages according to the established migration strategy and under the control of the security policy. The security framework is supportive of a plurality of security mechanisms and the dynamic migration strategies of the virtual machine, security of sensitive information of the virtual machine can be effectively protected, security attacks upon the dynamic migration of the virtual machine are resisted, and compatibility is high.

Description

technical field [0001] The invention relates to the technical field of computer information security, and provides a security framework, in particular to a virtual machine dynamic migration security framework. [0002] Background technique [0003] With the development of virtualization technology, many new technologies have emerged, among which virtual machine dynamic migration is unique to virtualization and one of its most important technologies. Virtual machine dynamic migration refers to the migration of a virtual machine from one virtual platform server to another virtual platform server on the premise that the virtual machine is running and can continue to provide services. Virtual machine dynamic migration realizes the rapid and transparent migration of virtual machine running status between physical machines through the network, which can be used for dynamic load adjustment, system online maintenance and active fault tolerance, flexible deployment of applications, ...
