Did you watch Charlie Chaplin’s immortal ‘Modern Times’ ? Where the protagonist is labouring furiously on the assembly line ! The automated assembly line is all about OT or Operational Technology. All of us have experienced OT in our lifetime, in some form or the other , in most aspects of our lives, but we rarely notice. Unlike IT, OT is quite invisible to our eyes. Because OT systems are primarily focused on controlling physical processes and infrastructure rather than managing administrative tasks. OT appear less visible compared to IT, because they have an infrastructure focus with limited public interaction with non end user facing as they require trained personnel to operate.

Now lets go back to basics

OT stands for Operational Technology. It refers to the hardware and software systems that are used to monitor and control physical processes in industries such as manufacturing, energy, transportation, utilities, and other critical infrastructure sectors. Unlike Information Technology (IT), which focuses on data processing and communication in business and administrative environments, OT is specifically designed for industrial operations.

OT encompasses a wide range of technologies, including industrial control systems (ICS), supervisory control and data acquisition (SCADA) systems, programmable logic controllers (PLCs), distributed control systems (DCS), sensors, actuators, robotics, and other devices and software used in industrial environments. These technologies are employed to monitor and manage processes such as manufacturing, power generation and distribution, water treatment, oil and gas refining, transportation systems, and more.

The primary objective of OT is to ensure the safe, efficient, and reliable operation of industrial processes. It involves real-time control, monitoring, and automation of physical systems and processes. OT systems are responsible for collecting data from sensors, analyzing it, and sending commands to actuators and other devices to control and optimize the industrial processes.

Here are some examples of Operational Technology (OT) systems commonly found in different industries:

Manufacturing

OT systems in manufacturing include industrial control systems (ICS), programmable logic controllers (PLCs), human-machine interfaces (HMIs), and supervisory control and data acquisition (SCADA) systems. These systems are used to control assembly lines, robotic arms, conveyors, and other machinery involved in the manufacturing process.

Energy and Utilities

In the energy sector, OT systems are utilized for power generation, distribution, and monitoring. This includes systems like SCADA systems for managing and controlling power grids, distributed control systems (DCS) for operating and controlling power plants, and smart metering systems for monitoring energy consumption.

Transportation

In transportation, OT systems are employed for managing and controlling various aspects of transportation infrastructure. This includes traffic control systems, railway signaling systems, air traffic control systems, and systems used in managing vehicle fleets and logistics.

Oil and Gas

OT systems are critical in the oil and gas industry, supporting activities such as drilling, refining, and pipeline operations. These systems include SCADA systems for monitoring and controlling oil and gas pipelines, distributed control systems for managing refinery operations, and safety instrumented systems for ensuring safe and reliable operations.

Water and Wastewater Treatment

OT systems are utilized in water treatment and wastewater management facilities. These systems include SCADA systems for monitoring water distribution networks, process control systems for managing treatment processes, and remote terminal units (RTUs) for data collection and control of pumping stations and reservoirs.

Building Management Systems

Building management systems (BMS) are OT systems used to control and monitor various aspects of building operations, including heating, ventilation, and air conditioning (HVAC) systems, lighting control, access control, and fire alarm systems.

Healthcare

In the healthcare industry, OT systems are used for medical equipment and infrastructure management. This includes systems for monitoring and controlling medical devices, HVAC systems in hospitals, and facility management systems to ensure the smooth functioning of healthcare facilities.

These examples demonstrate the diverse range of industries and applications where OT systems are employed. OT systems are integral to the efficient and safe operation of critical infrastructure across various sectors, and their security and reliability are of paramount importance.

As technology advances, OT systems are becoming increasingly connected to IT networks and the internet, enabling remote access, data exchange, and integration with enterprise systems. This integration has brought benefits such as increased operational efficiency, real-time analytics, and improved decision-making. However, it has also exposed OT systems to cybersecurity risks, as they were traditionally designed with a focus on safety and reliability rather than security. As OT systems have become vulnerable to cyber threats, need for enhanced cybersecurity measures has increased.

Henceforth securing OT systems has become a critical concern due to the potential impact of cyber-attacks on safety, production, and the economy. The evolving field of OT cybersecurity aims to protect industrial control systems and critical infrastructure from cyber threats, ensuring the integrity, availability, and confidentiality of OT systems and the processes they control.
