基于综合加权的层次化网络安全态势评估方法

Hierarchical network security situation assessment method based on synthetic weighting

针对网络安全态势评估中权值计算过于依赖专家经验,忽略了客观因子对态势决策结果的影响的现状,提出了一种综合加权的层次化网络安全态势评估方法;依据该指标体系综合赋权,由层次分析法计算主观权值和粗糙集方法计算客观权值,联合两种权值得到综合权值,并结合了因子加权求和法来综合分析当前网络安全态势状况。实验表明该方法切实可行,能更客观、准确地分析网络安全状况。

According to the problem that the weights calculation in the network security situation assessment excessively dependents on expert experience, ignores the influence of objective factors on the results of situation decision, this paper put forward a comprehensive weighted hierarchical network security situation evaluation method. According to the index system of comprehensive weight, by the hierarchical analysis calculation of subjective weights and rough set method calculated objective weights, combining two weights to get comprehensive weight, it combined with the weighting factor and comprehensive to analyze the current network security situation. Experiments show that this method is feasible and can be more objective and accurate.
