What evidence should teams collect for NIST SP 800-53A control assessments?
Start from the SP 800-53A assessment objective for the selected control, then decide which artifacts prove the objective at the required depth and coverage. Evidence should show both design intent and operating results when the assessment procedure calls for them.
Treat 800-53A assessment evidence as part of control implementation and assessment: define the scope, name the accountable owner, attach evidence, and set the next review trigger.
- Separate control selection from assessment evidence.
- Document tailoring, parameters, and inheritance explicitly.
- Use examine, interview, and test methods where assurance depth requires them.
