Addressing DDoS Attack in Software Defined Networks

Software-Defined Networking (SDN) is a new networking paradigm where the network intelligence is logically centralized in software-based controllers. In contrast, network devices become simple packet-forwarding devices that can be programmed via an open interface. Such decoupling of the control plane from the data plane introduces various challenges: security, reliability, load balancing, and traffic engineering. Dreadful security challenges in SDNs are denial of service (DoS) and distributed denial of service (DDoS) attacks.
This seminar discusses the DDoS attack problem in SDNs, including attacks, and an analysis of the existing solutions. Next, the current research work to address this problem is presented. Finally, some insights into the research extension and collaboration are discussed.
