Abstract
Since the current security situation assessment of information system has the problems of poor real-time perfor-mance and big error,an information system security situation estimation method based on data mining is proposed. The assert list and threat list after data discovery and preprocessing output are fed back to the security situation analysis and evaluation stage. For the analysis and evaluation of the security situation,all kinds of the threat factors triggering the risk are collected,and the Poisson distribution method is used to operate the frequency generated by the threat to assign the vulnerability of the system as-sets,and get the threat frequency. The fuzzy mathematics method is adopted to obtain the multi-factor and single-factor risk deci-sion of information system security situation estimation,analyze the risk loss degree,and acquire the comprehensive security evaluation value. The experimental results show that the method can evaluate the security situation of information system accurately.关键词
