网络安全风险评估与态势分析研究

Research on Network Security Risk Assessment and Situational Awareness

文章围绕目前国内外网络安全风险评估与态势分析模型进行分析与对比,指出各种方法的优劣,提出基于隐马尔科夫模型网络安全模型设计与实现,实验结果证明能提高事件分类准确性。

This paper introduces the methods of risk assessment and the models of situational aware-ness based on network security at home and abroad, gives the advantages and disadvantages among those research as well,then proposes the based on Hidden Markov model network security model de-sign and implementation, and the experimental results show that can improve the accuracy of classifica-tion of events.
