Hybrid Packet Marking IP Traceback Technique over IPv4, IPv6 and Mobile IPv6

-Cyber-attacks are increasing day by day. Each time attackers or malicious users come up with new techniques or methods in order to harm the network system of particular organization. While attacking on any organization, the main focus of the attacker is to successfully launch attack against organization’s network system by hiding its own identity under the identity of other legitimate user in order to not to get traceback. This technique is called IP spoofing. This technique is mostly used by the attackers while performing Denial of service (DoS) or Distributed Denial of service (DDoS) attacks. The need of IP traceback technique arises to trace the originator of the DoS and DDoS attacks. There are different kinds of IP traceback technique that are used to successfully traceback origin of the attack. In this research work, the Hybrid packet marking TTL and Hop Limit based identification technique is applied on IPv4 and IPv6 network respectively. In this technique, only the first router in the path marks its identity into the packet. In the IPv4 network, the first router in the path is identified using the TTL value of IPv4 packet header and in IPv6, the hop limit value is used to for the same. In the case of Mobile IP, where the attacking node is movable between the different networks, TTL based identification mechanism and Hop limit based hybrid traceback technique can be used for Mobile IPv4 and Mobile IPv6 respectively. In the mobile IP network, the address of home agent will be marked into the packet both for MIPv4 and MIPv6. In this research work, both the techniques i.e. hybrid TTL based identification and hybrid Hop limit based packet marking technique are simulated for wired and wireless IPv4 and IPv6 networks. The result shows the successful traceback of the nodes through the marking information in IPv4, IPv6 and Mobile IP
