Abstract
Nowadays, the term software-defined networking (SDN) becomes very popular. It is an approach that decouples the "control plane" and the "data plane" in switches to allow more programmable control of network traffic flows. Currently, several efforts are under way to thoroughly study and deploy SDN, as well as create standards that regulate the use of SDN. Since SDN is considered relatively a new discipline, a very little empirical literature has been aggregated in this field. The objective of this study is to aggregate and synthesize the empirical evidence from literature of SDN security to report the trends, patterns, and current status of the field. A systematic literature review (SLR) has been conducted to synthesize the empirical work in SDN.
