Abstract:

In this paper, we propose a new adaptive attack detection method for DDoS abnormal traffic attacks. The method is based on the characteristics of network access behavior for rapid learning modeling, and then through a traffic TOP-N ranking table to achieve dynamic filtering of abnormal traffic. The sample template of TOP-N table adopts adaptive convergence algorithm to quickly self-learning update. This method can quickly and accurately identify abnormal traffic and attack behavior, and greatly improve the accuracy of abnormal traffic attack detection. It is especially suitable for the detection and protection of slow application DDoS attacks.

Key words: DDoS, TOP-N, adaptive, training template
