| Abstract: | A fast online detection method aiming at DDoS(distributed denial of service) attack detection based wavelet transform was presented.The user-defined Socket method was adopted to capture network packets,the linked-list packets character library was responsible for keeping packets,and DDoS attack was detected online based on changes in the characteristic of network self-similarity which was estimated by using the real-time wavelet transform.The experiment results show that the detection can distinguish real DDoS attack from the massive data flow,and can effectively detect DDoS attack launched by unknown DDoS tools fast. |
