Deny by Default
A security posture where every action is refused unless a policy explicitly allows it - the safe state is the closed state.
Deny by default (also called default-deny) inverts the burden of proof: nothing is permitted until a rule grants it. Instead of listing what to block and letting everything else through, the system blocks everything and lets through only what policy names.
For AI it is the difference between a guideline and a control. If the enforcement layer is deny-by-default, a new tool, model, or data path is unreachable until it is explicitly approved - so an unforeseen action fails closed rather than slipping through an implicit allow.
