Operational Technology (OT) refers to the hardware and software systems used to monitor, control, and manage industrial operations and physical processes in real-time. Unlike Information Technology (IT), which focuses on data-centric computing systems, OT is primarily concerned with systems that interface with the physical world, such as sensors, actuators, and industrial control systems. OT is commonly found in sectors like manufacturing, energy production, transportation, and utilities, where it helps automate and optimize processes like assembly lines, power grids, and water treatment facilities. Due to its critical role in ensuring the smooth functioning of essential services and infrastructure, OT security is of paramount importance. In recent years, there has been a growing convergence of IT and OT, enabled by the Internet of Things (IoT), to facilitate better data analytics and operational efficiency. However, this integration also raises cybersecurity challenges, as traditional OT systems were not designed with internet-based threats in mind. Therefore, safeguarding OT environments has become a key focus in both industry and government policy.
