Cybersecurity of Industrial Internet of Things

The Internet of Things (IoT) is an emerging and even revolutionary technology with an immense impact on our everyday life. The Industrial Internet of Things (IIoT) is a fast-growing technology that increases productivity and efficiency by combining the IoT platform with an existing industrial environment. IIoT networks are one of the main pillars for the success of the future Industry 4.0 and Cyber-Physical System (CPS) paradigm. The IIoT ecosystem represents a network of connected industrial devices that exchange and analyze collected data to enable new insights into industrial processes. Recently, intensive research activities have focused on cybersecurity issues for the IIoT. This chapter addresses the critical components of the IIoT security framework by analyzing the relevant aspects and providing an overview of state-of-the-art activities in this field. This chapter also discusses the IIoT architectural structure, applications, and underlying networking technologies, with a particular focus on security challenges and standardization activities.
