Requirement
The confidentiality, integrity and availability of data at rest are protected.
What the engine looks for
Every group below must be satisfied — by an affirmative statement, not a plan, a hedge or a denial — for the control to count as covered. A term ending in … matches any word it begins. Supporting terms do not change the verdict — they raise confidence and distinguish a policy that names a mechanism from one that gestures at a category.

Contradiction markers
Finding any of these outranks coverage — a policy that admits the gap is worse than silence.
