A real-time DDoS attacks detection method based on entropy
Xinchun Yin · Journal of Yangzhou University · 2009
An efficient light-weight method for defending against DDoS attacks is designed in this paper.The entropy method based on a sliding window is used to compute the randomness of destination IP address of network packets in time.Then,VTP technology is used to detect abnormity.This method can detect the existence of DDoS attacks on line.According to experiments,the method in this paper can find out the DDoS intrusion against the large scale network,which does not arouse the sharp changes of the network traffic.
