General botnet use Command and Control (C&C) server and detecting C&C server is one of the technique of botnet measures. However, it is hard to detect C&C server because of diversification of C&C protocol and changing of botnet configuration. In our work, we define a feature vector to detect C&C server and report the experiment result that is classification normal traffic and C&C session by using real network traffic. Finally we show the effectiveness as the method of detecting C&C server which use several kinds of protocols. Keywords: botnet, C&C server, anomaly detection, machine learning 1.
