SDN Framework for Securing IoT Networks

Internet of Things (IoT) paradigm is the interconnection of machines, intelligent devices and location aware analytics platforms that collectively enable us to have smart world around us. As the billions of already connected devices and newly added devices grow this network, IoT pose the most complex operational and information technology challenges to the way networks are designed and operated. With the emerging technologies like SDN, SD-WAN, NFV, IXP evolving into standards, researchers are proposing new communication platforms to deliver secure and scalable networks for Internet of Things (IoT). In this paper, we discuss major security challenges in IoT networks and present the notion of security architecture for IoT based on programmable and virtualization technologies SDN/NFV, explain the architectural choices and its applications for IoT. We review prior works in this area and discuss our future work to solve security and privacy challenges of heterogeneous systems and networks in IoT.
