Research on the Vulnerability of Software Defined Network

Abstract

Abstract:With the continuous evolution of network technology, Software Defined Network (SDN) has become technical trends to solve the existing network problems. SDN is a new architecture of network. It decouples data plane and control plane, and simplifies network management. The same time, its vulnerability is also a crucial issue to its application due to openness and programmable. This paper deeply analyzed the vulnerability of SDN in control plane and application plane. Then the model of evaluating SDN's vulnerability is presented. With this model we got a security framework of SDN. Finally, we preliminary analyzed how to reduce the vulnerability of SDN.
