Cyber Security State of Industrial Internet of Things (IIoT)

Cybersecurity is a critical component of technology and must be considered during the early stages of the development of any system. Cyber security issues and challenges faced by IIoT are discussed in this paper. The first section of this paper focuses on Industrial Control System (ICS) environments where IIoT are deployed to understand the nature of business and technology companies with IIoT networks, followed by a comparison to understand the difference between Operational Technology (OT) and Information Technology (IT) networks and how both can be used to serve the need of business requirements. This paper evaluates the state of cyber security in industrial networks and IIoT and the safety and privacy concerns found in the literature. Solutions and improvement techniques introduced to cyber security functions mainly focus on prevention, detection, and response. Moreover, IoT organisational and operational security and cyber threat intelligence are also discussed. Finally, an approach is presented on how to conduct a security assessment on IIoT environments safely.
