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
