What is OT (Operational Technology)?
Operational Technology (OT) refers to the systems and technologies used in industrial and infrastructure settings to monitor, control, and manage physical equipment and processes. Unlike Information Technology (IT) that focuses on data processing and communication, OT is specifically designed for the operation of critical infrastructure and industrial facilities.
OT encompasses a wide range of hardware and software components, including programmable logic controllers (PLCs), supervisory control and data acquisition (SCADA) systems, distributed control systems (DCS), and industrial control systems (ICS). These technologies are responsible for managing and automating tasks in industries such as manufacturing, energy, transportation, and utilities.
The primary purpose of OT is to ensure the safe and efficient operation of complex systems. For example, in a power plant, OT systems are used to monitor and control the generation, distribution, and maintenance of electricity. In manufacturing plants, OT is responsible for overseeing production processes and managing the operation of machinery and equipment.
OT relies heavily on specialized protocols and standards to ensure secure and reliable communication between devices. These protocols, such as Modbus, Profibus, and OPC, facilitate data transfer and control functions between OT devices and the systems they interact with.
Traditionally, OT systems have operated in isolated environments, separate from enterprise IT networks to minimize the risk of cyber threats and ensure operational continuity. However, with the advent of the Industrial Internet of Things (IIoT), there is a growing trend towards the convergence of OT and IT, allowing for more efficient communication, data sharing, and better decision-making.
Overall, OT plays a crucial role in ensuring the reliability and safety of critical infrastructure and industrial processes.
