Abstract: Cloud computing is a distinct environment that is designed for sharing computing resources and services. It allows costumers and organizations to use its services without installing any software. It allows them to use cloud resources without investing in infrastructure and training personnel. But this technology suffers from the problem of different kinds of attacks. DDoS attacks are a critical threat to the cloud environment. Various traditional methods had been applied to mitigate them but due to their low efficiency and low storage capacity made these traditional approaches less useful and popular. So, in this paper we propose a dual mechanism in which packets are first filtered using their hop counts and then packets those are filtered are passed through the second phase of the mechanism in which packets are discarded on the basis of score calculated using the score also known as the conditional legitimate probability(CLP). The idea is to prioritize the packet based on this score which estimates the legitimacy of the given packet. Once the score is computed the packets will be selectively discarded on the basis of the static threshold.
