| Abstract | Software defined networks (SDN) has consider to be a new network architecture for managing the network dynamics via software-enabling control. SDN promotes a large number of network applications where security is an important factor. For security, SDN is a new paradigm emergent stage in the realm of production scale networks. Centralization of network control introduces a new level of flexibility for network administrators and programmers. Security is a significant factor for contributing the consumer resistance for implementation of SDN architecture. Without addressing the issues inherent from SDNs centralized nature, the benefits in performance and network configurative flexibility cannot be harnessed. This research presents security issues in SDN and specific review of SDN architecture along with the challenges faced. Furthermore, this paper explicitly discusses working mechanics of SDN and also analyzes its security issues and countermeasures. In a nutshell, it provides the SDN security features of uniqueness and openness. Moreover, this manuscript illustrates the SDN security issues from three aspects: data layer, control layer and application layer. Some countermeasures are also explained to address the security threats at each layer. |
