NIST 800-171 POA&M Template: Plan of Action and Milestones Explained

When to Use a POA&M

• Requirement status is Not Met or only partially implemented under your assessment methodology
• You need a documented path to Met before contract milestones or assessment windows
• Inherited-control gaps require vendor or CSP remediation you must track

POA&M Template Fields

Recommended fields for each item:

1. Weakness ID and linked 800-171 requirement (e.g., 3.3.1)
2. Description of the gap in system-specific language
3. Risk / impact note for prioritization
4. Remediation plan and milestones with dates
5. Resources required (people, budget, tools)
6. Owner and status (Open / In Progress / Closed)
7. Scheduled completion and actual closure evidence links

Close items only when the SSP implementation statement and evidence match Met status.

Relationship to SPRS Scoring

Under the DoD Assessment Methodology for 800-171 Rev 2, unmet requirements reduce your SPRS score from a starting point of 110 using weighted deductions. A POA&M does not by itself restore points — implementation does. Keep POA&M dates realistic; optimistic dates without funding are a common assessment finding.

How CyberSilo Helps

• Compliance Standards Automation — track open items against requirements and evidence
• ThreatHawk SIEM — produce monitoring artefacts that close AU/IR-related POA&M items

Frequently Asked Questions

Is a POA&M the same as a risk register?

Related but not identical. A risk register prioritizes enterprise risk; a POA&M is requirement-linked remediation tracking for 800-171 and related assessments.

Can you submit an SPRS score with open POA&M items?

Yes. Open items typically correspond to unmet requirements that already reduce the score. Document them honestly and keep remediation active.

Who owns POA&M closure?

Assign a named owner per item. Shared ownership without an accountable lead is a common reason dates slip.
