DDoS attack detection algorithm based on the correlation of IP address analysis

There are a huge number of network attacks on the Internet, and are increasing each year. The condition of internet attacks is developing toward a distributed, collaborative direction. Internet attacks exhaust a lot of resources, take up a lot of bandwidth,making the victim host can not accept normal network requests, resulting in substantial economic losses. This paper is based on the analysis of the distribution of network traffic, using detection method based on the analysis of the correlation of IP addresses.
