Distributed Denial-of-Service (DDoS) attacks are a critical threat to the Internet. It is extremely hard to trace back the attackers because of memory less feature of the internet routing mechanisms. As a result, there is no effective and efficient method to deal with this issue .In this paper, traces back of the attackers are efficiently identified and also to protect the data from the attackers using entropy variations. In the existing system, some approaches have been suggested to identify the attackers such as Probabilistic Packet Marking (PPM), Deterministic Packet Marking (DPM).
