Next generation infrastructures will be deeply impacted by the introduction of the Internet of Things, with the objective of improving their current operating models and methods. This follows the trend of the Web of Things (WoT), which projects to seamlessly connect various smart devices and IoT frameworks due to its flexible nature, hence, enabling new innovative services and opportunities. However, it also means that more and more data need to be protected from external threats and unauthorized accesses. Therefore, additional security and privacy mechanisms need to be deployed, together with an efficient management of these IoT devices. This issue becomes more convoluted and hardly tractable when dealing with several devices of the infrastructure dispatched over different physical Local Area Networks (LAN)s that we call “Smart Spaces” (SS)s. Thus, this paper proposes to solve this issue by introducing an architecture based on a Software Defined Networking controller for providing a secure access to the different SSs of a smart infrastructure, in a centralized way. We argue that a centralized view can greatly simplify and improve the security management of such infrastructures. Moreover, to support our assumptions, a Proof of Concept, with a concrete implementation of all the components is provided.
