| Abstract: | In this paper, we introduce the principle of DDoS briefly, and present a discussion and review of current detection mechanisms. Then we emphatically discuss a new abnormal detection solution, and adopt a new method-monitoring network flow in real time with packet filtering, in orderto set up one local defense system that defends DDoS attacks. |
