What is OT?

When managing complex computer systems comes to mind, as it does, many people immediately think of computer hardware, software, and networks in an office setting and the friendly IT department that installs, maintains, and troubleshoots said equipment.

But what about OT and ICS?

What the heck is that you ask?

OT, or Operational Technology, and its subset ICS, or Industrial Control Systems, are the backbone of many of the critical infrastructure assets, networks, and systems that make our modern quality of life possible, including power plants, manufacturing facilities, oil refineries, and water treatment plants.

🔧OT refers to the hardware and software used to monitor and control physical processes, devices, and infrastructure. Some examples would be the components used to monitor and adjust the temperature, pressure, and water levels necessary to safely run a boiler to produce steam to turn an energy-producing turbine.

🖥️Industrial Control Systems (ICS) manage and automate these processes, representing the command center that uses OT to monitor, coordinate, and control the components that make up these interconnected systems.

Why are OT and ICS so important?

1️⃣Critical Infrastructure: These systems are integral to operating and maintaining essential services like energy, water, and transportation. Without them, our day-to-day lives would be unrecognizable compared to what we enjoy today.

2️⃣Global Economy: OT and ICS drive industrial productivity, making them integral to supply chains, manufacturing, and resource management worldwide.

As vital industries and infrastructure become increasingly automated and connected, understanding and protecting these systems is crucial.
