What an assessor checks

NIST SP 800-171A breaks 3.6.1 into 7 objectives. Every one has to be met for the requirement to be met; a partial answer scores as not implemented.

  1. [a]Determine if an operational incident-handling capability is established.
  2. [b]Determine if the operational incident-handling capability includes preparation.
  3. [c]Determine if the operational incident-handling capability includes detection.
  4. [d]Determine if the operational incident-handling capability includes analysis.
  5. [e]Determine if the operational incident-handling capability includes containment.
  6. [f]Determine if the operational incident-handling capability includes recovery.
  7. [g]Determine if the operational incident-handling capability includes user response activities.

If it is open: POA&M eligibility

Not POA&M-eligible: above the 1-point ceiling · 5 points deducted

Worth 5 points. No requirement over 1 point may appear on a Level 2 POA&M, so this has to be closed before the assessment.

A POA&M is only permitted at a score of 88 or above, and closes in one 180-day window. Check a full gap list or compute your score.
