Coexistence attack defense method

Abstract

The invention relates to a virtual machine placement strategy selection apparatus, a coexistence attack defense method as well as a virtual machine deployment method and apparatus. The virtual machineplacement strategy selection apparatus comprises a strategy resource pool, a random number generator and a strategy selection module, wherein the strategy resource pool is used for storing all selectable virtual machine placement strategies; the random number generator is used for generating a random number of the virtual machine placement strategies selected by the strategy selection module; andthe strategy selection module is used for dynamically and randomly selecting the virtual machine placement strategy as a current virtual machine resource allocation request from the strategy resourcepool according to the random number provided by the random number generator and the load information of all servers. The corresponding virtual machine placement strategy is dynamically selected by utilizing the load information of all servers, so that the situation for predicting the attack of malicious users in the traditional method can be well solved; the ratio information of the servers is easy to calculate, the introduced calculation amount can be neglected, so that the calculation complexity is greatly reduced, and the practical value is high; and important guiding significance for thesecurity technique of the shared resource can be realized.

Description

technical field [0001] The invention belongs to the technical field of network security, and in particular relates to a virtual machine placement strategy selection device, a coexistence attack defense method, and a virtual machine deployment method and device. Background technique [0002] The cloud computing platform uses virtualization technology to share computing resources, which changes the original computing model and can improve the utilization, flexibility and availability of hardware resources. It has been widely used in many fields, such as government affairs, medical care, health, education, and finance. , national defense and so on. Virtualization technology abstracts the underlying physical resources, and can dynamically allocate resources according to user needs, which not only improves computing power, but also reduces energy consumption. In order to maximize the utilization efficiency of the underlying physical platform in the cloud computing environment, u...
