Abstract:

Recently, the need for programmable networks has drawn the interest of industrialists and academicians to develop a programmable networking paradigm called software-defined network (SDN). It is an effort made to separate network intelligence (control plane) from forwarding hardware (data plane). This paper provides a clear perspective of working of SDN and an open interface protocol called OpenFlow(OF). Researchers provide a broad insight into the working of SDN and various challenges faced while implementing it such as scalability, controller bottleneck, load balancing in distributed controller environment, routing and security. This paper focuses on security issues of SDN. We discuss different scenarios at which SDN is vulnerable to attacks and solutions to such attacks. Possible security attacks in the data plane, control plane and the interface between them are elaborated.
