Reflector Attack Traceback System with Pushback Based iTrace Mechanism

摘要

Reflector attack belongs to one of the most serious types of Distributed Denial-of-Service (DDoS) attacks, which can hardly be traced by traceback techniques, since the marked information written by any routers between the attacker and the reflectors will be lost in the replied packets from the reflectors. In response to such attacks, advanced IP traceback technology must be suggested. This study proposed an improved iTrace technique that identifies DDoS traffics with Push-back based multi-hop iTrace mechanism based on authenticated packet marking information at reflector for malicious reflector source trace and cope with DDoS attack packets efficiently.
