Simulated Raindrop Algorithm to Mitigate DDoS Attacks in Cloud Computing
Sourabh Bhagat, Syam Kumar Pasupuleti · 2015
Distributed Denial of Services (DDoS) Attacks are often the main source of cloud service disruptions. The considerable increase in DDoS attacks strength has drawn attention in detection and mitigation of DDoS attack. Due to use of more powerful botnets, DDoS attacks are harder to detect at the firewall, hence an efficient technique is required to mitigate DDoS attacks in cloud environment. In this paper, we present mitigation technique in cloud environment in swarm network with relay mechanism using Simulated Raindrop Algorithm (SRD), making it possible to model the defense strategy as mathematical optimization task. This algorithm is used with throughput maximization as fitness function. In the testbed setup, we have evaluated the performance of SRD with Intelligent Waterdrop Algorithm (IWD) through simulation and observed that SRD needs about 40%--45% less number of iterations for convergence. The results shows that proposed method can mitigate DDoS attack with high accuracy and achieves more robustness.
