Throughout the development of the network, the Software Defined Networking(SDN) paradigm introduced the transition of conventional networks by decoupling the forwarding hardware from the network’s control logic. The SDN architecture enables networks to track traffic actively and detect threats to promote network forensics, alteration of security policy, and insertion of security services. We discuss SDN-related technologies in this paper. In particular, we are attempting to cover the key components of SDN: architecture, security, and its implementations hoping that our efforts will help researchers set relevant and practical directions for future SDN research. In a nutshell, this paper highlights the current and future directions for secured SDN. This paper examines the architecture of SDN where we discuss the network-building methods that arise in the case of the network control being removed from the continuity with the purpose of planning. We further explore the need of guarding access, veracity, and confidentiality of the resources and data, coupled with the myriad security options available for SDN. Lastly, we discuss the diversity bestowed by SDN in different sectors.
