    Abstract: Cyber crime is one of the major threats for IT security. Internet crime refers to criminal exploitation of the internet. Issues surrounding this type of crime have become high-profile, particularly those surrounding hacking, copyright infringement etc. There are also problems of privacy when confidential information is lost or intercepted, lawfully or otherwise. Existing mechanisms use Packet Marking technique to trace back the real source of attacking packets that traverse through the network. But this mechanism fails to provide solution in case of IP SPOOFING and Path failures. In this study, we propose a finest solution to trace back the real source using pre-shared key authentication between egress router and the attacker node.
