MacTech CMMC / NIST 800-171

Get one NIST SP 800-171 Rev 2 security requirement by number (e.g. "3.5.3"): the full requirement text, its control family, and its exact DoD Assessment Methodology (SPRS) point weight, including the sliding-scale rules for 3.5.3 (MFA) and 3.13.11 (FIPS cryptography). Call this when the user asks what a specific 800-171 or CMMC Level 2 control requires or how many SPRS points it is worth. Pass sec

List NIST SP 800-171 Rev 2 requirements with their DoD Assessment Methodology (SPRS) weights, optionally filtered by control family name or by point weight (5, 3, or 1). Call this to enumerate the 110 CMMC Level 2 controls, to find all 5-point (highest-impact) requirements, or to see everything in one family such as Access Control. Returns identifiers and weights only - use lookup_control for one

Compute an exact SPRS score per the DoD Assessment Methodology: start at 110 and subtract each unimplemented requirement's Annex A weight (floor −203). Pass the control numbers that are NOT implemented; optionally pass 3.5.3 and/or 3.13.11 as partially implemented for their sliding-scale values (MFA for privileged/remote only = −3; encryption present but not FIPS-validated = −3). Also report

Get the official NIST SP 800-171A assessment objectives for one NIST SP 800-171 Rev 2 requirement - the exact "Determine if..." objectives a CMMC Level 2 assessor scores, plus the potential assessment methods (what an assessor examines, who they interview, what they test). Call this when the user asks how a control is assessed, what evidence an assessor will look for, or how to prepare a specific

Map a security control across frameworks: NIST SP 800-171 Rev 2 ↔ NIST SP 800-53 (FedRAMP Moderate) ↔ NIST CSF 2.0 ↔ SOC 2 Trust Services Criteria. Accepts an 800-171 number ("3.5.3"), an 800-53 id ("AC-2"), a CSF category ("PR.AA" style / "GV.RM"), or a SOC 2 criterion ("CC6"). Call this when the user asks what a control corresponds to in another framework, or how existing FedRAMP/SOC 2/CSF

Determine which CMMC level (1, 2, or 3) applies to a defense contractor based on the data they handle and the clauses in their contracts, and - separately - which assessment type may actually be designated today. Those are not the same question: CMMC Phase II was suspended on 13 July 2026, so C3PAO and DIBCAC assessments cannot currently be designated even where the level calls for one. Call this

List all 17 CMMC Level 1 basic safeguarding practices with their FAR 52.204-21 clause citations - the complete requirement set for contractors handling Federal Contract Information (FCI) only. Call this when the user asks what CMMC Level 1 requires.

Turn a list of unimplemented NIST SP 800-171 controls into structured Plan of Action & Milestones (POA&M) entries, and - the part that decides whether the plan is usable - sort them by eligibility under 32 CFR 170.21. Most gaps CANNOT go on a CMMC Level 2 POA&M: the rule bars every requirement worth more than 1 point (excepting 3.13.11 when encryption is employed but not FIPS-validated), bars six

Determine whether a contractor can legally be awarded a given contract type, based on the business systems that type requires. A cost-reimbursement contract may be awarded only if the accounting system is adequate for determining costs (FAR 16.301-3), and T&M billing cannot be substantiated without compliant timekeeping - so this is an eligibility gate, not a preference. Call this before a bid/no-

Explain what a FAR or DFARS cybersecurity clause obliges a contractor to do: what triggers it, the concrete duties, the reporting deadlines, what it flows down to subcontractors, and which other clauses come with it. Covers 52.204-21, 252.204-7008, 252.204-7012, 252.204-7019, 252.204-7020, 252.204-7021, 252.239-7010. Call this when someone asks "my contract has 7012 in it, what do I have to do", w

Work out which assets fall inside a CMMC assessment boundary, and what each category obliges. Returns the DoD asset categories (CUI Asset, Security Protection Asset, Contractor Risk Managed Asset, Specialized Asset, Out-of-Scope) with how each is treated at assessment, plus the CUI categories that most often pull a defense contractor into scope unexpectedly. Call this when someone asks what is in

Get one NIST SP 800-171 REVISION 3 requirement by its zero-padded number (e.g. "03.01.01"): the requirement statement, its organization-defined parameters, the 800-171A Rev 3 assessment objectives, and whether it was withdrawn. Rev 3 has 97 active requirements of 130 numbered across 17 families, with 88 ODPs and 422 objectives. IMPORTANT: Rev 3 is NOT currently binding for DoD contracts - DFARS 25

Explain how NIST SP 800-171 Rev 2 and Rev 3 differ, and what happened to a specific requirement between them. Call this when someone is implementing Rev 3 early, holds a Rev 3 citation and needs the Rev 2 obligation, or asks which revision applies to them. Answers the question DoD guidance forces on early adopters: assessments still run against Rev 2, so Rev 2 gaps must be closed regardless of wha
