Comparison between the mitigation approaches for the high-rate DDoS attacks in a cloud computing environment

The salient features of cloud computing (such as on-demand self-service, resource pooling, broad network access, rapid elasticity, and measured service) are being exploited by attackers to launch the severe Distributed Denial of Service (DDoS) attack. Generally, the DDoS attacks in such an environment have been implemented by flooding a huge volume (high-rate) of malicious traffic to exhaust the victim servers’ resources. Thus, the study of various DDoS attacks and their corresponding defense approaches becomes essential to protect the cloud infrastructure from fatal effects of DDoS attacks. This work is a comprehensive comparison of all the possible variants of cloud DDoS attacks solutions with detailed insight into the mitigation mechanisms.
