ICS

How it works

• It links sensors, controllers and a screen where an operator watches the process.
• It was built for reliability and long life, with little thought for security.
• Many run old software that cannot be easily updated.
• Connecting it to the office network can expose machinery to office threats.

What can go wrong (example scenario)

A small manufacturer connected its packaging line controller to the office network for remote help. A virus on an office laptop spread to the controller and stopped the line for two days.

• A bottling plant runs its line from a control panel.
• A building uses a control system for heating and ventilation.
• A water utility monitors pumps remotely.

A question owners ask

Does my office have one?

Only if you run machinery or building systems on a network, such as a factory line or automated heating. If you do, ask your provider to keep it separate from office devices.
