Abstract

The (Distributed) Denial of Service (DoS/DDoS) attacks have become the main devastating threats to web services, and generally, the Probing attacks are the prior steps of DoS/DDoS attacks. To achieve the aim of the information assurance, an intrusion detection mechanism based on the Vector Quantization (VQ) technique is proposed for countering DoS/DDoS and Probing attacks in this paper. The normal network traffic usage profile can be modeled and represented by the codebook of VQ from which the abnormal behavior deviation of TCP traffic can be measured quantitatively well. In data processing, according to the characters of DoS/DDoS and Probing attacks, we implement the novel feature extraction of TCP flow state. We apply the detection mechanism to DARPA Intrusion Detection Evaluation Data Set. It is shown that the network attacks are detected with more efficiency and relatively low false alarms.
