FAQGLOBALNIST SP 800-53 Rev. 5

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

A useful POA&M item identifies the finding, affected control and system, risk response, owner, milestones, status evidence, dependencies, and closure criteria.

Keep the assessor's finding separate from management's remediation plan and the authorizing official's risk decision.

Overview

A plan of action and milestones () records how an organization intends to address identified weaknesses or deficiencies. SP 800-53A places the POA&M in the with the security and privacy plans and assessment reports, but SP 800-53 and SP 800-53A do not prescribe one universal item-level form. Use the applicable agency or program template. At minimum, make the source finding, affected scope, response, ownership, milestones, status, dependencies, and closure basis reviewable.

Question 1

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

Preserve the assessor's determination statement and finding separately from management's response. The may reference that result, but it should not rewrite the evidence or turn an unresolved finding into a completed action.

Record planned and actual milestone dates, required resources, changes to scope or response, delays, dependencies, and evidence for status updates. SP 800-53 control CA-5 requires the organization to define how often its is updated; a contract, agency policy, authorization program, or internal procedure may impose additional fields and deadlines. Close the item only under that applicable process after corrective work and any required reassessment or validation are complete.

Risk acceptance, authorization, and status are separate decisions. The gives the authorizing official current plans, assessment reports, the POA&M, and related information for a risk-based decision. A POA&M entry does not itself prove control effectiveness, authorize operation, or document that the appropriate official accepted residual risk.

  • Identify the source assessment or finding, affected system or program, control or requirement, and the exact weakness or deficiency.
  • Describe the planned risk response, responsible owner, required resources, dependencies, milestones, and scheduled completion dates.
  • Record interim safeguards when they are part of the approved response, without presenting them as closure evidence.
  • Define the evidence and governance step needed to close the item, including reassessment when required by the applicable process.
  • Track approved changes, missed milestones, status evidence, and any separate residual-risk decision.

Question 2

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

Use the organization, agency, contract, or authorization program's required fields and workflow. The checklist below is Sorena's explanation of a reviewable record, not a replacement for a mandated template, reporting system, due date, or risk-response process.

  • Link the item to the original assessment report, determination statement, finding identifier, and affected control or requirement.
  • State the affected boundary, asset, service, information type, or process precisely enough to assign and verify the work.
  • Name the response owner and milestone owners; record planned and actual dates rather than silently replacing missed dates.
  • Attach evidence for each status claim and keep pending, completed, validated, and closed states distinct.
  • Record dependencies, interim safeguards, approved deviations, and separate risk decisions with their authorities.
  • Before closure, confirm the corrective action and complete any reassessment or other validation required by the applicable governance process.
