CMMC Readiness

> Portability: 3 stdlib scripts, no network, no SPRS connection. Fill CSVs, run, keep the output with the SSP.

> Not an assessment and not legal advice. A C3PAO or DIBCAC assessor decides MET; the Affirming Official affirms in SPRS.

Level 2 assessments fail in predictable ways: a 5-point gap someone planned to

put on a POA&M, an SSP that misses half the assets, a cloud drive holding CUI

without FedRAMP, and a Conditional status that quietly expires on day 181. Each

script catches one of these before the assessor does.

Workflow

# 1 - Scope: what is in the assessment, and what must the SSP say about it?
python scripts/scope_classifier.py --inventory assets/inventory.example.csv
# 2 - Score: what is the SPRS score, and can we reach Conditional or Final status?
python scripts/sprs_score.py --assessment assets/assessment.example.csv --output json > score.json
# 3 - Closeout: is the POA&M complete, deferrable, and on time?
python scripts/poam_closeout.py --score score.json --poam assets/poam.example.csv \
  --conditional-date 2026-06-15 --as-of 2026-11-01

Step 1 sorts every asset into the 32 CFR 170.19 categories (CUI, Security

Protection, Contractor Risk Managed, Specialized, Out-of-Scope) and blocks on

in-scope assets missing from the inventory or SSP, and on any cloud provider

holding CUI without FedRAMP Moderate or an equivalent body of evidence.

Step 2 scores all 110 requirements (5, 3 or 1 point; partial credit only for

MFA and FIPS encryption; the SSP unscored but mandatory). It lists what must be

fixed before any assessment and what may go on a POA&M, and says how many points

short of 88 you would still be after fixing the blockers.

Step 3 checks the POA&M against the score: every deferred gap has an item,

nothing ineligible is on it, every open item has an owner and a date before the

180-day deadline. It also prints the status calendar: closeout deadline, expiry,

and annual affirmation dates.

The gates block on (exit 4)

1. CA.L2-3.12.4 not met: no current SSP means no assessment can finish.

2. A NOT MET requirement worth more than 1 point (except SC.L2-3.13.11 encrypted but not FIPS-validated).

3. A NOT MET AC.L2-3.1.20, AC.L2-3.1.22, PE.L2-3.10.3, 3.10.4 or 3.10.5: never deferrable.

4. A score under 88 after everything deferrable is deferred.

5. POA&M items still open after the 180-day closeout deadline, or an annual affirmation missed.

6. An in-scope asset missing from the SSP or inventory, or a CSP holding CUI without FedRAMP.

Hard rules

• Unassessed is not MET. The score script refuses a file that does not list all 110 requirements.
• MET means every objective. The assessor tests the 320 NIST SP 800-171A objectives; one unmet objective makes the requirement NOT MET. Mark MET only with evidence per objective.
• Score against Rev 2. 32 CFR 170 and DFARS class deviation 2024-O0013 keep Level 2 on NIST SP 800-171 Rev 2; plan Rev 3 in the SSP roadmap, not the POA&M.
• NA needs a reason the assessor will accept. An NA without one is reported.
• A POA&M is not implementation. Deferral buys 180 days, not a waiver.
• Never affirm for anyone. Name the Affirming Official; the scripts only prepare the evidence.
