ABSTRACT
Advancements of the Internet of Things (IoT) provide several opportunities for automating industrial applications such as smart cities, intelligent logistics, smart grids, smart manufacturers, etc. IoT interconnects a colossal number of heterogeneous devices with the Internet and performs intelligent collaboration with other devices anywhere, anytime, and leads to a technologically optimistic future. Though the IoT has made considerable progress in the industry, there are still a few challenges, including network heterogeneity, network scale, the sheer amount of data generated, and privacy and security, which are considered major concerns in the design of IoT frameworks and architectures. Privacy and security are major concerns in the IoT, where various heterogeneous devices are interconnected in order to communicate with each other. The IoT is facing challenges, which include lack of user awareness, absence of robust and efficient security protocols, and lack of active device monitoring. The IoT is more susceptible to attacks; therefore, to achieve the level of security it requires, various security techniques are needed. In this chapter, various security measures and IoT system backgrounds have been explored. This chapter presents a general survey and analysis of the following things: (i) various security and privacy issues, and (ii) suitable security protocols and models at various IoT layers. This chapter further discussed the potential suitable IoT solutions based on different communication protocols, security mechanisms, cryptography, and intrusion detection systems. A critical analysis is performed and identified the potential research gaps for future work.
