Abstract
The current methods have poor application effects in network security situational awareness,with high RMSE and FAR,which cannot achieve the expected perception effect.To address the shortcomings and deficiencies of the current methods,a network security situational awareness method based on multi-sensor information fusion is proposed.Select security situation elements from three aspects:host,attack,and common,establish a network security situation element index system,use multiple wireless sensors to perceive network security data,preprocess it,and quantify the network security situation through multi-sensor information fusion,completing the network security situation perception of multi-sensor information fusion.Experimental results have shown that the RMSE of this method is less than 0.1 and the FAR is within 1%,which can achieve accurate perception of network security situations.关键词
