A survey on security in software-defined-networking

Abstract

With the development of data and systems administration advancements, ordinary system frameworks have not had the capacity to adapt up to the expanding request. To meet this requirement SDN (Software Defined Networks) was proposed; the idea was simply to decouple the control layer, the application layer and the infrastructure layer and connect them using application programming interfaces or APIs. SDN empowered network managers and gave rise to automated network management which is evident in the cloud infrastructure of today. Notwithstanding, there are many system security issues with respect to SDN, which require problem solving. In this paper, we undertake a survey for the field of security implementations in SDN and review existing countermeasures against known threat to the network.
