The essence of the Internet of Things (IoT) resides on the concept of a wide variety of devices that connect and share data at any level in synergy with the current Internet framework. The IoT defines embedded devices capable of interacting with users and other devices over a network infrastructure with limited or nonexistent user interaction. There is a seamless integration between us and the “things” around us. This means that devices become part of our experience. Every device is connected to every other device, communicating with one another, transferring and retrieving data, intelligently responding, and triggering actions. The successful implementation of the IoT requires the consideration of a number of important factors including but not limited to the communication technologies, communication protocols, hardware and embedded devices, and the software. A significant surge of IoT devices has been recorded in the past few years and the tendency seems to continue. It is predicted that by the end of 2020 there will be around 20 billion connected devices (Gartner, 2015). The data exchanged over the network will be greater than 40 Zettabytes for the same period (Forbes, 2016). This brings up an important discussion regarding the security of the data generated, stored, and transmitted by IoT devices and the privacy of the users who produced or consumed the data. Every approach of IoT system must be secure and provide the necessary controls and privacy to the users. Successful implementation of an IoT system is possible only when the security and privacy are built, rather than adding the protection as a “decoration” layer on top of an IoT system. This paper discusses the security issues at different levels of IoT systems. Section II describes the IoT architecture and current standardization efforts. Section III provides a highlevel overview of current security problems and environment. Section IV presents a dive-in view of the current IoT enabling technologies and protocols focused on each of the layers of the IoT architecture. Section V discusses the IoT security concerns under the security triad perspective and explores some of the current privacy issues of the IoT from a few different points of view. Finally, Section VI summarizes the ongoing security challenges in IoT and lays out a few promising approaches.
