Industrial IoT (IIoT) security has gained tremendous importance in recent years. With the rise of IIoT and the increasing integration of operational technologies (OT) with the internet, the need for robust security measures has become paramount. Industrial IoT, often referred to as OT, has transformed industries across the board. The advent of 5G technology has made OT assets integral to the manufacturing, healthcare, and robotics sectors. These technologies have improved operational efficiency and enhanced worker safety by reducing accidents in industrial settings.

In the past, OT systems operated in isolation; however, they are interconnected today, leading to more efficient and complex systems. Remote operations have also become increasingly common, highlighting the need for secure IIoT infrastructure. While IIoT offers numerous benefits, it also introduces security challenges. Connecting OT systems to the internet inherently involves some level of risk. Recent news reports have highlighted industrial cyberattacks, such as the Ukrainian electric grid attack and the Saudi oil refinery attack, showcasing the vulnerabilities of increased connectivity.

Ransomware attacks, in particular, have emerged as a significant threat to the manufacturing sector. In 2021 alone, there were ten successful ransomware attacks targeting manufacturing companies. The consequences of such attacks are severe, disrupting production, encrypting data, and causing financial losses.
