Abstract
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.
I. INTRODUCTION
Billions of objects will be connected to the internet in the coming years. Therefore, it is expected a real revolution on the amount of data gathered and shared. This is known as the Internet of Things (IoT). Everyday objects, such as home appliances, lampposts, traffic lights or irrigation outlets, are some examples of smart things. They are equipped with several sensors generating data, which then should be gathered and analyzed.
VI. CONCLUSIONS
We have demonstrated the feasibility to use an SDNenabled security framework and we have proposed a security architecture for IoT devices, which is based on the principles of SDN. A simple algorithm has been implemented to analyze the feasibility of statistical analysis for anomaly detection. We have introduced the proposed SDN security application for IoT by interconnecting the ADRENALINE and IOTWORLD testbeds, running on top of an SDN/NFV-enabled edge node. Finally, we have demonstrated the flow interruption anomaly mitigation technique.
Further research on security for IoT needs to be performed, but using the powerful framework on SDN, has been demonstrated as a useful weapon against security threads.
