IP traceback through modified probabilistic packet marking algorithm
Y. Bhavani, V. Janaki, R. Sridevi · 2013
Denial of service (DOS) attack is one of the most common attacks on the internet. The most difficult part of this attack is to find the source of the denial of service (DOS) attack. Savage et al. proposed PPM algorithm to traceback the route to the attacker. We found two disadvantages of the Savage traceback technique. The first disadvantage is probability of finding of far away routers is very less which results in losing some of the routers identity. This affects the attack graph construction. The second disadvantage is, because of re-marking of the edges the constructed graph contain new edges which do not exist in attack graph. In this paper, we propose a modified probabilistic packet marking (MPPM) IP traceback methodology and we found that the results are quite interesting when compared with the approach proposed by Savage.
