IPv6 Traceback Using Policy Based Management System
Syed Obaid Amin, Choong Seon Hong, Dongjin Kwak, Jaehwa Lee · 2008
Most of the cyber attacks use spoofed IP packets to cast an attack. The stateless nature of IP makes it nearly impossible to identify the true source(s) of these attacks. With the help of IP traceback techniques, we try to identifying the true source of an IP datagram in Internet. While many IP traceback techniques have been proposed, but most of the previous studies focus and offer solutions for DDoS attacks done on IPv4 environment. IPv4 and IPv6 Networks differ greatly from each other, for instance, absence of the Option field in basic IPv6 header. Thus, the mechanisms of IP Traceback for IPv4 networks may not apply to IPv6 networks. In this paper, we extend our previous work i.e. PPM for IPv6 and remove its drawback by using Policy Based IP Traceback (PBIT) mechanism. We also discuss problems related to previously proposed IPv4 traceback schemes and practical subtleties in implementing traceback techniques for IPv6 networks. * Keywords: IPv6 Traceback, Policy-based Management, PBIT 1.
