网络安全综合评价的AHP可拓分析方法

AHP Extension Comprehensive Evaluation for Network Security

本文提出对网络安全进行综合评价的层次分析法与可拓评价分析法的集成模型。构建目标层、准则层、一级指标、二级指标的四级三层评价体系,利用层次分析法确定二级指标对目标的权重,通过可拓关联分析把专家的评分转化成综合评价结果。应用实践表明,上述模型与方法实现了定性评价与定量评价的统一,能为管理者提供比较客观、准确的综合评价结果。

This paper presents a model used in comprehensive evaluation for network security,which is combined with analytical hierarchy process（AHP） and extension theory. A multi-level indicator system which contains goals, key factors, first-level indicators and second-level indicators is set up in this model. Each indicator＇s weight can be obtained through AHP and the evaluation result can be extracted from expects scores by extension relation analysis. Practical application cases show that such method is capable of providing object and exact results for managers since it is based on both qualitative analysis and quantitative analysis.
