Abstract: Analyzed the essential characteristic of the network security situation assessment, and the reasoning model is proposed。The Method for Network Situation Assessment Based on Fuzzy Pattern Recognition and D-S Evidential Theory is effective in solving the problem of the information uncertainty and improving the probability of accurate recognition。The result of simulation shows the method is satisfactory。

Key words: Network Security, Situation Assessment, Fuzzy Pattern Recognition, D-S theory

摘要: 分析了网络安全态势估计问题的本质特征,构造了网络安全态势推理评估的求解模型。采用模糊模式识别和D-S证据理论相结合的不确定性推理方法,能较好地解决多样本识别的不一致问题,有效地对识别结果进行融合,从而得到较高的正确识别率。通过实例说明了方法的有效性。
