NIST SP 800-53 Rev. 5 What should a POA&M item include for NIST SP 800-53 Rev. 5 control gaps?

A POA&M item should state the control gap, risk, affected system, required remediation, owner, milestone dates, evidence needed for closure, and approval path for any residual risk or delay.

Use this SP 800-53 answer to make a source-linked decision, assign an owner, and keep evidence reviewable.

Question 1

What details belong in a POA&M item for NIST SP 800-53 Rev. 5 control gaps?

Use a POA&M item to turn a control gap into a clear action record: describe the deficiency, name the impacted system, assign ownership, and set the next review point so the work can be tracked to closure.

Keep the entry practical and reviewable so teams can see what needs to change, who is responsible, and what evidence will show the gap has been resolved.

  • Separate control selection from assessment evidence.
  • Document tailoring, parameters, and inheritance explicitly.
  • Use examine, interview, and test methods where assurance depth requires them.

Question 2

What practical checklist should teams use for POA&M items under NIST SP 800-53 Rev. 5?

Use this NIST SP 800-53 Rev. 5 checklist to turn POA&M items into implementation work that can survive review: define the decision, attach source evidence, assign ownership, document gaps, and set a reassessment trigger.

  • Write the decision and scope in one sentence.
  • Attach the source-linked evidence that proves the current state.
  • Name the accountable owner and backup reviewer.
  • Record unresolved gaps, accepted risk, and dependencies.
  • Set a date or event trigger for reassessment.
