基于SIR模型的无线网络安全威胁态势量化评估算法
Quantitative Assessment Algorithm for Security Threat Situation of Wireless Network Based on SIR Model
摘要
Abstract
To ensure network security and timely control the security situation,a security threat quantification assessment algorithm is proposed for wireless networks based on susceptible,infected,and susceptible infected recovered models.Asset value,system vulnerability,and threat are selected as quantitative evaluation indicators.Value and vulnerability quantification values are obtained based on the security attributes of information assets and the agent detection values of host weaknesses,respectively.Based on the propagation characteristics of the virus,the SIR(Susceptible Infected Recovered)model is improved,the propagation characteristics of the virus are analyzed.A quantitative evaluation algorithm for wireless network security threat situation is established based on the quantification of three indicators,and the obtained situation values is used to evaluate the network security situation.The test results show that the security threat situation values of the host and the entire wireless network evaluated by this method are highly fitted with the expected values,and the evaluation time is shorter.It can be seen that the proposed algorithm has good evaluation accuracy and real-time performance,which can provide effective data basis for network security analysis and provide reliable decision-making support to administrators in a timely manner.关键词
