Mapped NIST 800-53 r5 controls (1)

Our two-way, human-QA’d reading of how this category and each NIST 800-53 control relate. No external body publishes an OWASP→800-53 mapping, so these are our assessment.

Direction: ← other covers this; → this covers other (F/M/P = full / mostly / partial). gov = governs / implements (a mandate, not coverage).
