A reference model for securing IoT

As Internet of Things(IoT) involvement increases in our daily lives, several security and privacy concerns arise which stem from two main contributing factors. One is IoT lacks a building-blocked reference model in which a common ground and enabler technologies of IoT can be understood and identified. The other factor is the absence of widely-accepted IoT security and privacy guidelines and their appropriate implementation techniques for the previously mentioned enabler technologies. Therefore, our work is divided into three parts. First, we propose a novel four-layered IoT reference model based on building blocks strategy, in which IoT asset-based attack surface is divided into four main components or layers. Second, we propose a framework of security and privacy guidelines for each IoT asset mentioned above, which can be utilized to reinforce IoT security and privacy by design. Third, we propose a novel five-phase methodology for securing IoT objects based on their Security Level Certificates (SLCs).
