摘要
Abstract
In order to automatically assess the present network security situation, the authors propose a hierarchical network security risk assessment methodology. Its principles are as follows:first,DS theory is laid as the foundation for correlatively fusing alert data;then,based on weight value analytical methodology and hierarchical analysis technique,from bottom to top and from local to global,it calculates the security situation value for every hierarchical layer. Experiments based on real network environment illustrate that the assessment results are more accurate;furthermore,the hierarchical methodology based security situation presentation methodology is more straightforward and understandable. Compared with existing methods,the proposed method not only intensifies the evidence about alert data but also overcomes the weakness of present hierarchical assessment systems at fuzzy treating.关键词
