Data centre (server room): what it is and how it is attacked

The building or room where the servers physically live.

Also known as

  • server room
  • colocation
  • comms room

Typing any of them into the editor finds this object.

Why it matters on a security diagram

Physical access removes assumptions that most other controls rest on, which is why the access list matters as much as the firewall rules.

How it gets attacked, and what reduces it

How it gets attacked

  • Access lists never reviewed after people leave

What reduces it

  • Review the access list after every leaver, not on an annual cycle
  • Keep building systems off the network that serves the servers they cool
