SECURITY IN SOFTWARE DEFINED NETWORKING: A REVIEW

Software Defined Networking (SDN) is the latest paradigm shift in the domain of enterprise networking with clear & distinct advantages over classical view of networking. Many models and architectures are being proposed to take advantage of the inherent advantages. The academia and industry is excited about the possibilities of innovations. Although the advantages are obvious, there have been concerns raised about the security of SDN. In this paper we have highlighted the various challenges that are faced by academia and industry while implementing SDN in carrier and enterprise markets. We have identified security concerns in SDN and have tried to apply classical and modern security primitives to this new paradigm. We realize that the security primitives have to be embedded at the protocol and architecture levels for a smooth and seamless solution. This paper presents a review on security challenges of SDN.
