Break-glass procedure
A documented emergency route for gaining access, or making a change, when the normal controls are unavailable or not enough. It usually needs extra approval and is always logged so it can be reviewed afterwards. Why it matters: Emergencies happen, and without a planned route people make undocumented changes in a hurry.
