Collaborative peer to peer defense mechanism for DDoS attacks

Distributed Denial of Service (DDoS) attacks are the most common and easiest attacks to propagate over internet. It causes a high degree of destruction to the network and systems resources. The destructive nature of DDoS attacks force security engineers to design defense solutions which can detect and take counter actions to defend against such attacks. In this paper, we investigated the packet flood attacks and presented a collaborative peer to peer defense mechanism. The proposed solution detects the attack at victim edge router and sends the alert messages to its neighboring nodes which allow them to proactively defend themselves. Simulation results shows the efficiency of the solution with less false positives at victim edge router and less damage to the network due to proactive defense approach.
