摘　　要：为解决冗余量化评估要素影响安全态势评估准确性的问题,提出矩阵修正的电力信息网络安全态势量化评估方法。分析网络安全态势评估要素量化空间指标,引入矩阵修正方法,修正要素量化矩阵。模糊处理量化结果,划分危害等级。计算量化区间一致性程度,调整矩阵元素,获取关联系数,累积威胁程度,构建电力信息网络安全态势量化的评估模型。在量化空间内以网络脆弱性指数、威胁性指数为指标,实现安全态势量化评估。实验结果表明,该方法网络可靠程度评估与实际相符,最小态势误判率为2%,具有较为精准的评估效果。In order to solve the problem that the redundant quantitative assessment factors affect the accuracy of security situation assessment,a matrix-modified quantitative assessment method for power information network security situation is proposed.This paper analyzes the quantitative spatial index of network security situation assessment elements,and introduces the matrix correction method to modify the quantitative matrix of elements.Fuzzy processing quantifies the results and classifies the hazard levels.The consistency degree of the quantified interval is calculated,the matrix elements are adjusted to obtain the correlation coefficient and accumulate the threat degree,all of which build the evaluation model of the security situation quantification of the power information network.In the quantitative space,the network vulnerability index and threat index are used as indicators to realize the quantitative assessment of security situation.The experiment results show that the network reliability evaluation of this method is consistent with the reality,and the minimum situation misjudgment rate is 2%,which has the accurate evaluation effect.
