Low rate DOS traceback based on sum of flows

摘要

Denial of service is one of the most common and biggest threats on the Internet done by spoofing in the IP address source. It leads to using the system resources and declines the system performance. In this paper level of flow will be used to traceback the denial of service source based on ant colony and metaheuristic algorithm. The simulation results show that the proposed approach can trace the attacks even if the attack traffic intensity is relatively low. By initializing the algorithm parameters correctly, the probability of errors will reach to its lowest rate or even to zero which is considered as an effective step in tracing attacks by means of meta-heuristic algorithm.
