You periodically check that your controls actually work.
What it actually means
Don't assume your controls work — verify them periodically. A self-assessment against the 110 requirements (which is what generates your SPRS score) is exactly this. The point is to confirm controls are effective in practice, not just configured.
Pass or fail — an assessor needs a "yes" to each
- Controls are assessed periodically for effectiveness.
- Results are documented.
- Findings feed your POA&M.
What to have ready
- Self-assessment results (e.g., SPRS scoring)
- Assessment cadence/policy
- Findings -> POA&M linkage
Where teams trip up
- Never re-assessing after the first time
- Assuming configured = effective
- No documentation of the assessment
