Reputation-based model for defending DDoS in muti-tenant cloud

DDoS attack, prevent, multi-tenant, cloud computing system, reputation-based

tenant cloud is facing a serious Distributed denial of service attack.The attackers first control a series of virtual machines, and then launched a serious DDoS attack through these virtual machines.Because of the difficulty of detecting the source and the tragic of the attack in the cloud, it is difficult to detect and prevent the distributed denial of service attack. A method to prevent the distributed denial of service detection was presented which is suitable for multi-tenant cloud environment. This method defines the reputation for every computer node. By the reputationof computer node, the method can prevent the distributed denial of service. The effectiveness of the proposed method is proved.
