ABSTRACT
This chapter presents the security usability problem in the context of Internet of Things (IoT). The technician installing his home security system had very little understanding about how computer systems and networks work. The chapter explores the challenges of security usability and principles for designing usable security as it pertains to IoT systems. IoT security architects and engineers must realize that the IoT system and its security mechanisms are being built for users who are largely uninterested in the engineering or security specifics of the system. If security is designed into a system in such a way that it impedes the objective of the system, such security becomes a barrier to the necessary usage of the system. Security architects play an important role in ensuring that the vision, design, and implementation of security features are in harmony.
