基于模糊矩阵博弈的网络安全威胁评估

Threat Assessment of Network Security Based on Fuzzy Matrix Game Theory

在分布式网络安全积极防御系统中,需要进行多层次的信息融合。其中层次较高的威胁评估是根据网络安全态势感知结果,推测或判断威胁程度以及可能的行动方案。该文在分析博弈论中模糊矩阵博弈原理和网络空间威胁评估机理的基础上,提出了基于模糊矩阵博弈的网络安全威胁评估模型及其分析方法,并给出了计算实例与研究展望。

In the distribut e intelligence network security active defense system,data fusion is composed of multi-level processes.The threat assessment ,which is the highest order proce ss of data fusion,inference or detect on intrusion threats or malicious activit y according to the cyber-space situation assessment.By analyzing the fuzzy ma trix game (FMG)theory and threat assessment mechanism,a new model for threat assessment based on FMG theory and its analysis method are presented in this p aper.At the end,an applied sample is given and some new development areas a re proposed as well.
