摘要: 为了实时描述电力信息网络的宏观安全状况,提出了一种层次化的网络威胁态势评估方法并予以系统实现。该方法通过灰色聚类分析将各种网络威胁按危害程度划分为强、中、弱3类,并以这3类作为层次分析法中准则层的设计依据,再利用层次分析法构造层次化的评估指标体系并确定各种网络威胁的权重。将各种网络威胁的权重与其实时发生次数加权求和得到网络威胁态势值,其数值大小反映了电力信息网络实时安全状况。最后的实验和系统运行情况表明,该方法可有效地展示电力信息网络安全状况,有助于提高其安全防护水平。

Abstract: To describe the macro safety situation of electric power information network in real-time, an hierarchical threat situation evaluation method is proposed and implemented. This method adopt the gray clustering analysis to categorize the damage degree as strong, medium, weak in total 3 types, based on which the principle layer of the analytic hierarchy process is designed. According to the evaluation index system of the structure layer of analytic hierarchy process, the weight of the cyber-threat is confirmed. And the cyber-threat situation value can be obtained by the weighted summation of each cyber-threat weight and its real-time occurrence frequency, which reports the real-time safety situation of the electric power network. The final experiment and system operation shows that, this method may effectively describe the safety situation of electric power network and be helpful for the development of safety and protection level.

Key words: electric power information network, cyber-threat, situation evaluation, analytic hierarchy process
