Internet of Things (IoT) is a novel paradigm, which not only facilitates a large number of devices to be ubiquitously connected over the Internet but also provides a mechanism to remotely control these devices. The IoT is pervasive and is almost an integral part of our daily life. As devices are becoming increasingly connected, privacy and security issues become more and more critical and these need to be addressed on an urgent basis. IoT implementations and devices are eminently prone to threats that could compromise the security and privacy of the consumers, which, in turn, could influence its practical deployment. In recent past, some research has been carried out to secure IoT devices with an intention to alleviate the security concerns of users. The purpose of this paper is to highlight the security and privacy issues in IoT systems. To this effect, the paper examines the security issues at each layer in the IoT protocol stack, identifies the underlying challenges and key security requirements and provides a brief overview of existing security solutions to safeguard the IoT from the layered context.
The term Internet of Things (IoT) was first introduced by Kevin Ashton of MIT’s Auto-ID lab in 1998 @cite_60 . IoT is believed to be the most influential technology of the generation after Internet. The number of interconnected physical devices is significantly increasing and it has already surpassed the human population in 2010. There has been significant work in the development of IoT-enabled devices in the recent time. The advances in the technologies in terms of resources constrained and energy-efficient devices have extended the outreach of internet even to the remote locations also. The number of interconnected physical devices have exceeded all expectations.

Abstract The Internet of Things as an emerging global, Internet-based information service architecture facilitating the exchange of goods in global supply chain networks is developing on the technical basis of the present Domain Name System; drivers are private actors. Learning from the experiences with the “traditional” Internet governance it is important to tackle the relevant issues of a regulatory framework from the beginning; in particular, the implementation of an independently managed decentralized multiple-root system and the establishment of basic governance principles (such as transparency and accountability, legitimacy of institutional bodies, inclusion of civil society) are to be envisaged.
