攻击容忍系统通过对病毒入侵路径和频率进行扫频实现对病毒的挖掘，传统的扫频方法采用相位和频率特征匹配方法进行，对网络病毒非规则方向入侵不能起到较好的掩盖作用，扫频效果不好。提出一种采用病毒传播方向聚类分析的攻击容忍系统扫频方法，构建病毒传播路径分析模型，建立病毒传播的方向性空间搜索属性序列，分析病毒传播方向聚类演化模型，实现对病毒传播和入侵传播方向聚类过程的建模，求解病毒传播方向的聚类属性的信息熵，实现攻击容忍扫频改进算法。实验结果表明，算法能有效实现对病毒传播和扩散的时间和频率等信息进行扫频分析，病毒时频特征得到有效挖掘，通过扫频检测准确率较传统该方法提高13.6%。

Attack tolerant system based on virus intrusion path and frequency sweep is used for mining the virus, sweep fre?quency by using the traditional method of phase and frequency feature matching method, the network virus irregular direc?tion of intrusion cannot play a good masking effects, sweep the effect is not good. The analysis using a virus propagation di?rection clustering attack tolerant system frequency sweep method, constructing the analysis model of virus propagation path, a search attribute sequence directional space to establish the transmission of the virus, virus propagation direction of cluster evolution model is constructed, modeling of the spread of the virus and intrusion propagation direction of the cluster?ing process is obtained, information entropy clustering attribute for virus propagation direction the attack tolerance, sweep algorithm is improved. The experimental results show that the algorithm can effectively realize the time and frequency on the spread of the virus and the diffusion of information such as frequency analysis, virus time-frequency features can be ef?fectively mined, by sweeping detection the accuracy is improved 13.6%.than traditional the method.
