SDN-Enabled Secure IoT Architecture Development: A Review

Abstract

AbstractThe Internet of things (IoT) is a revolution in the technological future. We expect it to affect everything, from virtually all forms of automation to everyone, living or non-living, and in multiple ways. Every network entity contributes to the generation of huge amounts of data, and network objects exchange these data buckets over the Internet for seamless transfer of control. With the use of numerous digital technologies, each network object receives, interprets, and utilizes the data on account of non-standard intrinsic properties, thus creating an exploit opportunity for malicious users, hence compromising the security and privacy of the data. With such significant effects on society through technological advancements, trust in IoT-based systems is necessary. The key to this trust lies in security advancements and enhancements in IoT connectivity, implying that IoT must exhibit some level of reliable, secure, and private behaviors. This paper proposes the development considerations for secure IoT architectures. The discussion varies over various aspects of IoT architecture features, challenges that arise when adopting an IoT security architecture, security techniques proposed in recent years, and how software-defined networking (SDN) and SDN controllers help alleviate these aforementioned security concerns. This paper also highlights some of the existing industrial IoT frameworks and comparison of certain primitive SDN controllers.KeywordsPrivacyAuthenticationSDN controllersIoTOpenFlowSDNSecurityCyberphysical systems
