Software Defined Network Security: A Study

This paper will give you a brief and some knowledge about the Software Defined Network (SDN) Security. Based on the general definition of software defined network we know that it is made up of number of nodes, and it decouples the network control and data plans. The network across the world helps to transfer and enables to connect data. Software Defined Network is a astute networking technique, as its infrastructure is abstracted from conglomeration and its states are rationally centralized. The SDN architecture authorize networks to diligently monitor traffic and diagnose threats to facilitates network forensics, safety carrier insertion and safety policy transformation. The SDN model is foremost controlled by a central unit called controller. All the communication takes place through this controller. However, it has a drawback of getting hacked. The entire system crashes if the controller fails, the complete system will get corrupted or breakdown. This paper highlights the present and future security challenges in Software Defined Network (SDN).
