Survey Paper on Alleviation of Cloud Internal Denial of Service Attacks

Cloud computing security is now becoming one of the main concerns preventing the adoption of the cloud by many organizations. This paper surveys the attacks done on cloud and their mitigation strategies to defend the cloud specic CIDoS class of attacks (Cloud-Internal Denial of Service). The alleviation approaches are based on techniques used in signals processing eld. The main strategy to detect the attack is the calculation of correlations measurement and distances between attackers workload patters; we use DCT (Discrete Cosine Transform) to accomplish this task. This paper also suggests some prevention and response strategies.
