摘要:

针对目前安全态势感知(SA)范围局限、信息来源单一、时空复杂度较高且准确性偏差较大等问题,提出了一个全方位因子加权感知网络安全态势框架,充分考虑了多信息源与多层次异构信息融合,从整体动态上展示出网络当前安全状况,准确地反映了网络安全态势.最后利用网络实例数据,对所提出的因子加权的网络安全态势感知模型和算法进行了验证,实验结果表明了所提方法的正确性.

关键词: 多源信息, 信息融合, 加权因子, 安全态势感知

Abstract:

Concerning the problem of present network security Situation Awareness (SA) that scope is limited, time and space complexity is high with the issues of single source information and accuracy deflection, a framework of network security situational awareness with comprehensive factor weighted factor was presented. It fully considered the multiple-source and multi-level heterogeneous information fusion, thus displayed the network current security situation overall and reflected it accurately. Finally from instance data of network, the proposed model and algorithm of weighted factor network security situational awareness were verified, and the experimental results showed the validity of the proposed method.

Key words: multi-source information, information fusion, weighted factor, security Situation Awareness (SA)
