Real-Time Detection of DDoS Attack Based on VTP
Ruchuan Wang · Dianzi xuebao · 2007
To detect DDoS attack accurately and in time,the performance of real-time method based on VTP was evaluated,and the effectiveness of this method is proved.Using this method to calculate the Hurst parameter of traffic data set of Lincoln Lab of MIT,the law of change of Hurst parameter during DDoS attack is found—it is that the Hurst parameter increases faster at the beginning of an attack and then it decreases slowly;while the traffic is all DDoS attack traffic,the Hurst parameter descends absolutely(from 0.95 to 0.45).So a technology of detecting DDoS attack on real-time is proposed.
