摘要
为解决异构多传感器网络环境下出现的告警信息冲突问题,提出了一种基于网络安全态势感知的告警信息冲突处理架构模型.通过设置各传感器针对不同形态攻击的置信度和权重,来改善D-S证据理论数据融合的结果,以及应用模糊认知图模型进行全局告警信息融合,解决告警信息冲突问题.
In order to resolve alarm conflict of heterogeneous network sensors,an architecture is put forward based on network security situation awareness.Alarm fusion results of weighted Dempster-shafer theory of evidence are improved by setting the confidence and weight of alarms.Then Fuzzy Cognitive Maps are used to fuse the multiple inputs.Finally,the final alarms help to resolve alarm conflict.
