Introduction to IoT Security

In a world with “things” and devices interconnected at every level, from wearables to home and building automation, to smart cities and infrastructure, to smart industries, and to smart‐everything, the Internet of Things (IoT) security plays a central role with no margin for error or shortage on supply. Securing, including authentication of these devices, will become everyone's priority, from manufacturers to silicon vendors (or IP developers), to software and application developers, and to the final consumer, the beneficiaries of the security “recipe” that will accompany these IoT products. Together, all consumers of these products need to adapt to the market demands, innovate, and improve processes, grasp new skills and learn new methods, raise awareness and embrace new training and curricula programs.In this chapter, we provide a thorough survey and classification of the existing vulnerabilities, exploitable attacks, possible countermeasures as well as access control mechanisms including authentication and authorization. These challenges are addressed in detail considering both the technologies and the architecture used. Furthermore, this work also focuses on IoT intrinsic vulnerabilities as well as the security challenges at every layer. In addition, solutions for remediation of the compromised security, as well as methods for risk mitigation, with prevention and suggestions for improvement are discussed.
