They might be deployed anywhere – inside an automated manufacturing floor, outside a chemical processing plant managing valves and switches, on a rig in the middle of the ocean, or out in the arctic monitoring oil and gas pipelines. OT systems often perform simple yet essential tasks, such as monitoring a valve and shutting it off when a certain value is triggered. As a result, they can perform their tasks with little change for years. Which also means they sometimes run on aging operating systems and obsolete hardware using home grown applications.
