Security in Internet of Things: Challenges, Solutions and Future Directions

Abstract

Internet of Things (IoT) is an enabler for the intelligence appended to many central features of the modern world, such as hospitals, cities, grids, organizations, and buildings. The security and privacy are some of the major issues that prevent the wide adoption of Internet of Things. In this paper, with example scenarios, we are presenting review of security attacks from the perspective of layers that comprises IoT. In addition, a review of methods that provide solutions to these issues is presented along with their limitations. To overcome these limitations, we have provided future work recommendations with a framework. Further research and implementation of the framework and our recommendations will further enhance the robustness and reliability of the IoT and their applications against a variety of known attacks.
