Problems solved by technology

[0004] The current mimic defense system is mainly based on credibility to uniformly control the execution bodies of heterogeneous virtual machine platforms. In the process of control, the influence of newly added execution bodies on the local and overall robustness of the system is not considered, and it is impossible to achieve Fundamentally strengthen the active defense capability of the mimic system

Embodiment Construction

[0027] The present invention will be described in further detail below with reference to the accompanying drawings and examples.

[0028] Such as figure 1 As shown, this example is defined in the perception decision-making unit and works in the dynamic scheduling unit. There are the following execution bodies in the heterogeneous execution body pool:

[0029]

[0030]

[0031] Execution e running at the current time 1 , e 2 , e 3 , e 4 , e 5 , e 6 , there is an executive e in the candidate executive pool 7 , e 8 , e 9 , e 10 , e 11 , e 12 .

[0032] Such as figure 2 As shown, this example is implemented through the following steps:

[0033] Step 1. According to the input error results of each running execution body within a period of time, 0, 1, 2, 0, 0, 0, further calculate the confidence of these execution bodies, and obtain the execution body e 3 The one with the lowest confidence level has the highest threat level. According to the calculation formul...

Abstract

The invention discloses an executor unified control method of a heterogeneous virtual machine platform. According to the method, the local isomerism degree and the global isomerism degree are comprehensively considered, on the premise that the probability of having the same vulnerability between the isofunctional isomers can be ignored, in the consideration of the local isomerism degree, a Manhattan-like distance is taken as an entry point, and an optimal solution of local replacement is precisely defined and normalized; In consideration of the global isomerism degree, the information entropyis taken as an entry point, and the problem that a local optimal solution and a global optimal solution cannot be obtained at the same time is solved. The whole method preferentially satisfies the maximization of local heterogeneity, and then considers the maximization of global heterogeneity, thereby fundamentally improving the defense capability of the mimicry defense system.

Description

technical field [0001] The invention belongs to the technical field of network security mimicry defense, and relates to a unified control method for execution bodies of a heterogeneous virtual machine platform. Background technique [0002] In the basic system of mimic defense, the dynamic heterogeneous redundancy mechanism is its essential core idea. It is a defense mechanism with uncertainty, and it has heterogeneity (the structural composition of the two executive bodies with equivalent functions is different, and this difference can ensure that the same attack will not cause the two executive bodies to fail at the same time. ), redundancy (diversification of heterogeneous parallel execution bodies in the working set, by increasing the number of execution bodies in the working set of heterogeneous The presented work executors, utilization and other functional executors have excellent and effective features such as insensitivity to normal requests and incompatibility with...
