Doctrine
Three habits, borrowed from older crafts. Boring on purpose — that's what survives contact with production.
I · Defense
Hold the line
Defense in depth, not in slides. Least privilege, segmented networks, keys that rotate before anyone asks. A phalanx holds because every shield covers the next.
II · Endurance
Keep the long watch
Most of the job is uneventful — that's the win. Certs that renew themselves, backups tested on a schedule, alerts that stay silent until they mustn't. The watch is kept by showing up.
III · Response
Move when it must
When something breaks, response is muscle memory, not meetings. Runbooks that actually run, rollbacks one command away, automation that draws fast and clean.
