The intermittent attacking behavior of Pulsing Denial of Service (PDoS) attacks poses a real challenge to the existing DoS detection methods. In this paper, an adaptive method is presented to meet this challenge. Three features distinguish this method from others. No assumption is made on the distribution of the traffic samples. Automatic adjustment of the detection threshold according to the traffic conditions. Timely detection of the end of a PDoS attack. Simulation results validate the efficacy of the proposed method in source-end detection of PDoS attacks.
