Software Defined Networking (SDN) based Secure Integrated Framework against Distributed Denial of Service (DDoS) Attack in Cloud Environment

Cloud computing is nowadays developed as a scalable and cost-effective technique. It facilitates many features in the computing environment like resource pooling, multi-tenancy, virtualization etc. In order to avoid resource maintenance, computing has been done on the service provider's infrastructure. Data security is the main concern in cloud computing because it is stored in data centers provided by service providers. DDoS attacks are rapidly growing in the cloud environment and have become a serious threat to cloud consumers. SDN is used to identify and prevent DDoS attacks in the cloud and it simplifies network complexity. In this paper, we have proposed a method that detects and mitigates DDoS attacks in cloud computing using the features of SDN with high accuracy and low computational cost. The proposed system is able to block the illegitimate users and allow only legitimate users to access the cloud services. The results are calculated by simulation experiments.
