Problems solved by technology

[0002] Scheduling is an important mechanism for mimetic web servers. Existing scheduling algorithms focus on the improvement of defense capabilities due to heterogeneity, but lack the defense against the vulnerabilities of each executive in the mimetic web server, which cannot solve the security caused by vulnerability attacks. , and failed to consider the quality of service of the pseudo-constructed web server for the attacker's false response, thus failing to solve the problem of the adverse impact of heterogeneous executive responses on the quality of web services

Embodiment Construction

[0028] The present invention will be further described in detail below in conjunction with the accompanying drawings, so that those skilled in the art can implement it with reference to the description.

[0029] Such as figure 1 As shown, the present invention provides a kind of execution body dispatching method oriented to mimetic structure Web server, comprising:

[0030] Step 1: Generate a set of candidate executables, randomly select m executables from the set of candidate executables, calculate the mean value of the vulnerability value and the standard deviation of the vulnerability value of each layer of the software stack of each of the m executables, from Among the m execution bodies, select n execution bodies with the average value of the vulnerability value and the standard deviation of the vulnerability value within the range of the threshold value of the vulnerability value, as the execution body set I, where m and n are both integers greater than 0; alternative ex...

Abstract

The invention discloses an executive scheduling method for a mimicry structure Web server, which comprises the following steps of: 1, generating an alternative executive set, randomly selecting m executive bodies, calculating a vulnerability value mean value and a vulnerability value standard deviation of each layer of software stack, and screening n executive bodies positioned in a vulnerabilityvalue threshold range; 2, randomly selecting two QoS parameters, and calculating QoS parameter values; 3, mapping the Bayesian-Stackelberg game model to a web server of the mimicry structure, and constructing an objective function for solving an optimal scheduling strategy; 4, substituting the two QoS parameter values into the target function to obtain k actuators with optimal QoS parameter values; and step 5, generating a random number r, and if r is greater than or equal to epsilon, dynamically scheduling the heterogeneous executors of the mimicry web server according to the k executors. Themethod has the beneficial effects that the confusion is increased and the defense capability is improved while the service quality of the Web server is ensured.

Description

technical field [0001] The invention relates to the field of Web server defense. More specifically, the present invention relates to a method for scheduling executives oriented to web servers with mimetic construction. Background technique [0002] Scheduling is an important mechanism for mimetic web servers. Existing scheduling algorithms focus on the improvement of defense capabilities due to heterogeneity, but lack the defense against the vulnerabilities of each executive in the mimetic web server, which cannot solve the security caused by vulnerability attacks. , and failed to consider the consideration of the service quality of the pseudo-response to the attacker by the pseudo-constructed web server, thus failing to solve the problem of the adverse impact of heterogeneous executive response on the quality of web service. Contents of the invention [0003] It is an object of the present invention to solve at least the above-mentioned problems and to provide at least t...
