Not the Office — Looking After the Computers That Run Machines

The computers that run machines and physical processes aren't office PCs, and the office security playbook doesn't fit them. They control physical things, can't just be patched or rebooted, are often old, and put safety and uptime first. Treat them differently: keep them separate, change them carefully, and work with the people who run them.

What you'll learn

• See the computers that run machines (OT) as a different kind of thing from office computers (IT) — where a cyber problem becomes a physical, safety problem.
• Know why you can't just patch or reboot a running control system, and weigh OT decisions by availability and safety first.
• Keep the plant's control systems separate from the office network, and change them carefully with the people who run them.
• See through the traps of 'it's just like the office computers' and 'it's not connected, so it's safe'.
