Executor Scheduling Method Oriented to Mimetic Construction Web Server

Abstract

The present invention discloses an execution body scheduling method oriented to a web server with a mimic structure, comprising: step 1, generating a candidate execution body set, randomly selecting m execution bodies, and calculating the average value of the vulnerability value and the standard deviation of the vulnerability value of each layer of software stack , to screen n executives within the threshold range of the vulnerability value; step 2, randomly select two QoS parameters, and calculate the QoS parameter value; step 3, map the Bayesian-Stackelberg game model to the mimic structure On the web server of , construct the objective function for solving the optimal scheduling strategy; step 4, bring two QoS parameter values ​​into the objective function, and obtain k execution bodies with the best QoS parameter values; step 5, generate random number r , if r≥ε, then dynamically schedule the heterogeneous executables of the mimic web server according to the k executables. The invention has the beneficial effects of increasing confusion and improving defense ability while ensuring the service quality of the Web server.

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...
