Abstract:
The Internet has brought a revolution in today’s life. Future of Internet is even
more promising because of emerging technologies like ubiquitous computing, context
sensitive, adaptive and reconfigurable applications. Security is the most important issue
concerned with Internet. Internet is exposed to threats like system penetration, financial
fraud, theft of proprietary information, Denial of Service (DoS)/Distributed Denial of
Service (DDoS) Attacks etc. Currently, DoS/DDoS attacks are the most expensive
computer crimes. The attacker launching this type of attacks commonly masks his identity
using IP spoofing. It is very difficult to identify the sources of a DoS/DDoS attack. IP
traceback methods are used to locate the source of packets causing DoS/DDoS. Existing
IP traceback techniques cannot trace every type of DoS attack. The main objective of the
project was to develop a new IP traceback technique capable of tracing any type of DoS
attack. The proposed technique is particularly designed for networks supporting both
wired and mobile nodes. That is, it is compatible with IPv4 and IPv6 for wired IP
networks and Mobile IPv4 for mobile IP networks.
