域名請求行為特征與構(gòu)成特征相結(jié)合的域名變換檢測
[Abstract]:To avoid the problem of domain name blacklist blocking, a botnet detection method based on domain name request behavior feature and domain name composition feature is proposed. In this method, support vector machine (SVM) (SVM) classifier is used to analyze the domain name which failed to resolve the host in the network, and the suspected infected host is extracted. Through the cluster analysis of new domain names, the host set requesting the same group of new domain names is used as the detection object, and whether the request host collection is made up of suspected infected hosts is analyzed. The collection of domain names currently used by botnet and the set of IP addresses used by command and control (Command and Control,CC) server are extracted. The experimental results show that the SVM classifier can achieve 98.5% accuracy after training, and the IP address of the infected host and CC server can be accurately extracted by monitoring the ISP domain name server.
