ABSTRACT
The industrial Internet of things (IIoT) can be regarded as machines, computers, and people enabling intelligent industrial operations using advanced data analytics. It is a network of systems, objects, platforms, and applications that can communicate and share intelligence. This chapter introduces the concept of IIoT along with its security challenges and applications. It covers in detail about the existing security issues in the area of cyber physical systems (CPS) and evolution of IIoT with a secure design pattern. IIoT is an amalgamation of various technologies, like big data, machine learning, machine-to-machine communication, sensor data, and automation that have been involved in the industrial backdrop for past years. CPS was developed from the massive application of embedded systems. CPS is considered as the core part and foundation of Industry 4.0. CPS provides maximum benefits and will exchange industrial operations. CPS will focus on technologies, concept, challenges, and architecture. IIoT becomes more manageable if all the software, policy, and updates are up to date. The deployed version of the automation system should be carefully controlled, managed, and configured. Periodic compliance report about security is advisable and mandatory.
