摘要
当前 ,对网络的安全状况进行定量分析和预警日益显得重要 ,文中通过对漏洞库中的大量漏洞信息进行分析 ,提出对网络安全脆弱性的威胁程度进行定量分析的层次分析模型和指标体系 ,采用图论的方法对各种安全脆弱性信息进行关联分析 ,并在此基础上构造入侵关系图模型 ,给出基于入侵关系图的网络安全威胁分析方法 。
at present it is becoming more important to analyze network security state quantitatively and alarm in advance, the paper analyzes a lot of vulnerabilities' characteristics and proposes a analytic hierarchy process model and a series of indexes, it applies a graph theory method to analyze the association problem among vulnerabilities and construct intrusion relation graph model, the paper also proposes several computing methods of network security state, at the end of the paper analyzes the implementation prototype of the whole network security analysis and evaluation system.
