Improving Security in Internet of Things with Software Defined Networking
2016
Future Internet of Things (IoT) will connect to the Internet billions of heterogeneous smart devices with the capacity of interacting with the environment. Therefore, the proposed solutions from an IoT networking perspective must take into account the scalability of IoT nodes as well as the operational cost of deploying the networking infrastructure. This will generate a huge volume of data, which poses a tremendous challenge both from the transport, and processing of information point of view. Moreover, security issues appear, due to the fact that untrusted IoT devices are interconnected towards the aggregation networks. In this paper, we propose the usage of a Software- Defined Networking (SDN) framework for introducing security in IoT gateways. An experimental validation of the framework is proposed, resulting in the enforcement of network security at the network edge.
