层次化网络安全威胁态势评估技术研究
Research on hierarchical network security threat situation assessment
摘要
Abstract
In order to estimate the security situation of large-scale network, this paper aimed at confidentiality, integrality and availability, adopted hierarchical analysis, and put forward a quantitative evaluation model for network security threats situation. This model included a suit of security threat situation indices composed of service, host, subnet and whole network, and quantitative calculation method for each index. Experimental results show the easy operation of this model, and it depicts the safety evolution process of network system accurately and intuitively.关键词
