Mitigation of Cloud-Internal Denial of Service Attacks

Cloud computing security is one of the main concerns preventing the adoption of the cloud by many organisations. This paper introduces mitigation strategies to defend the cloud specific CIDoS class of attacks (Cloud-Internal Denial of Service), presented in [1]. The mitigation approaches are based on techniques used in signals processing field. 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.
