If It’s Not Documented, It Doesn’t Exist
Security relies on knowing what you have, who owns it, and how it works. Without documentation, systems become black boxes — and risks go unnoticed.
Incident Response Depends on Good Docs
When a breach happens, responders need to know which systems are affected, how to isolate them, and who to contact. Every minute lost to guesswork increases damage.
