This work presents a new graph-based approach for the detection and isolation of botnets in a computer network. Our approach depends primarily on the temporal co-occurrences of malicious activities in the different computers in a network and is independent of the underlying botnet architecture. It additionally includes mechanisms to deal with temporal variations seen in a botnet-such as the variations in online bot population, in botnet growth patterns, in malicious activity durations, and so on. Results on real and simulated traces indicate that the graph-based approach can segment out botnets with high accuracy under varying conditions.
