Abstract :
In the analysis of the characteristics of network traffic we proposed a method for web site network security. We separate efficiently users by cookie, analyse user´s activity by Hidden Semi-Markov Model, caculate the normal degree and allocate the bandwidth for the normal users. So we can defense DDoS attacks and control abnormal network traffic flow.
