Review on DDoS Attack in Controller Environment of Software Defined Network

Distributed Denial of Service (DDoS) attacks pose a significant threat to the security and availability of networks. With the increasing adoption of Software-Defined Networking (SDN) and its multi-controller architectures, there is a need to explore effective DDoS attack detection mechanisms tailored to these environments. An overview of the current research on detecting DDoS attacks in SDN environments, with a focus on different detection techniques, methodologies and problems is presented in this survey paper. The survey attempt to identify the limitations and strengths of current approaches and propose potential research directions for improving DDoS detection in this context.
