Baoxu Liu · Jisuanji gongcheng · 2012
In order to assess the historical security states and forecasts future network security situation,this paper proposes a loose coupling network security situation awareness model by using survivability analysis based on Kaplan-Meier method.It uses survivability analysis method to get loose coupling between multi-source information fusion and security situation awareness method.A representation analysis of example with multi-type nodes based on KDD99 is given for security situation assessment.And it illustrates the superiority of this model in adapting the dynamic changes of network structure and multi-source data.The applicability and correctness of model is validated by drawing the graph of security situational awareness and comparing the results of security situational awareness with historical security states.
