Securing IOT devices using SDN and edge computing

In the current technological perspective, we are witnessing a tremendous increase in the connection of heterogeneous devices and controlling them remotely. One of the latest technologies enabling this concept is “IoT” (Internet of Things). According to historical evidence, anything which is connected to a network is vulnerable to hacking and illegal monitoring. Since the devices which are being connected would be directly controlling human life, the security of these devices becomes paramount. Especially when IoT is turning “heterogeneous networks” into “super-heterogeneous networks” of intelligent devices, securing it becomes very complex. There are different methods of providing security to a network available today but none is infallible. SDN being an intelligent networking paradigm which can rapidly and automatically reconfigure network devices, reroute traffic and apply authentication and access rules can open up a way for better security and access control mechanisms. In this paper, an attempt has been made to devise a method of providing security to IoT using SDN (Software Defined Network) & Edge Computing.
