基于情景感知的网络安全风险评估模型与方法
Network Security Risk Assessment Model and Method Based on Situation Awareness
摘要
Abstract
In view of network security situation awareness framework's lack of a precise mathematical quantitative method to network information security risk assessment,a network risk assessmeht model based on network security situation awareness framework is proposed by combining DS evidence theory and Consultative Objective Risk Analysis System(CORAS).Network security threats information fusion and situation perception based on DS evidence theory,hierarchical risk quantitative analysis based on probabilistic risk analysis,and risk discrimination.Low earth orbit satellite communication network is taken as an example to make a simulation and assessment.Experimental results show the proposed model and method can effectively identify threat situation,and increase the accuracy of risk assessment discriminant.关键词
