Abstract： By utilizing the characteristics of resource sharing in cloud computing, attackers can launch DoS attack by constantly consuming bandwidth resources so that other users on the same physical host can not receive normal services. This attack mode is different from the DoS attack in traditional network system, so it is difficult to apply traditional defense method to solve it. To solve this problem, this paper proposes a DoS attack defense method based on virtual machine migration. By selecting the migration target, designing the triggering mechanism and selecting the migration destination, a virtual machine migration strategy is proposed to mitigate the impact of DoS attacks. The experimental results demonstrate that this method can effectively defend DoS attack and ensure the normal operation of cloud service whatever different attack methods that attackers may use. Compared with other methods, the proposed strategy leads a litter more migration cost, however, it’s better in defense effect and feasibility.
