This paper provide the way of finding the legitimacy of a packet by analyzing the number of hops that packet gone through before reaching at the destination. Problem with IP packet is that the contents of the packet can be changed easily. This is called IP spoofing, which is being very much used in Distributed Denial-of-Service (DDoS) attacks. they are very hard to detect, there is no comprehensive solution.
