Network Security in Software defined Networks (SDN)

Based on the generalized definition of a network, we know that it is made up of a number of nodes. Sending and receiving of data takes place via these nodes. This process is characterized by the permission provided and requirement of sharing data. Basically, networking helps the nodes across the globe to connect and enable data transfer. Software Defined Networking (SDN) is a smart networking technique. It brings together other disciplines with networking for example, programming, research etc. The SDN model is predominantly controlled by a central unit called controller. All the communication takes place via this controller; however, it has a disadvantage. If the controller anyhow fails or is hacked, the entire system will either fail or get corrupted. In this paper disadvantage of the SDN has overcome with the relevant solution.
