Credit Based Methodology to Detect and Discriminate DDOS Attack From Flash Crowd in A Cloud Computing Environment
N.Jeyanthi, Hena Shabeeb and Mogankumar P.C, VIT University, India
ABSTRACT
The latest trend in the field of computing is the migration of organizations and offloading the tasks to cloud. The security concerns hinder the widespread acceptance of cloud. Of various, the DDoS in cloud is found to be the most dangerous. Various approaches are there to defend DDoS in cloud, but have lots of pitfalls. This paper proposes a new reputation-based framework for mitigating the DDoS in cloud by classifying the users into three categories as well-reputed, reputed and ill-reputed based on credits. The fact that attack is fired by malicious programs installed by the attackers in the compromised systems and they exhibit similar characteristics used for discriminating the DDoS traffic from flash crowds. Credits of clients who show signs of similarity are decremented. This reduces the computational and storage overhead. This proposed method is expected to take the edge off DDoS in a cloud environment and ensures full security to cloud resources. CloudSim simulation results also proved that the deployment of this approach improved the resource utilization with reduced cost.
