CMMC
DoD certification verifying cybersecurity for defense contractors
ISO 17025
International standard for competence of testing and calibration laboratories
Quick Verdict
CMMC mandates cybersecurity certification for DoD contractors protecting FCI/CUI, while ISO 17025 accredits testing labs for technical competence and impartiality. DoD firms adopt CMMC for contract eligibility; labs pursue 17025 for global result acceptance and trust.

CMMC Details
What It Is
Cybersecurity Maturity Model Certification (CMMC) 2.0 is a U.S. Department of Defense (DoD) certification framework ensuring cybersecurity protections for Federal Contract Information (FCI) and Controlled Unclassified Information (CUI) in the Defense Industrial Base (DIB). It uses a tiered, risk-based model with three cumulative levels: Level 1 (basic FCI safeguards), Level 2 (NIST SP 800-171 for CUI), and Level 3 (NIST SP 800-172 enhancements against APTs).
Key Components
- 14 domains (e.g., Access Control, Incident Response) with 17 (Level 1), 110 (Level 2), or 134 (Level 3) practices
- Built on FAR 52.204-21, NIST SP 800-171 Rev 2, and NIST SP 800-172
- Assessment via self, C3PAO, or DIBCAC using interview/examine/test methods
- POA&Ms allowed with 180-day closures; SPRS/eMASS reporting
Why Organizations Use It
Mandated for DoD contractors/subcontractors handling FCI/CUI to gain contract eligibility, reduce supply chain risks, and achieve competitive advantage. Enhances resilience, lowers breach costs, builds prime trust.
Implementation Overview
Phased approach: scoping, gap analysis, remediation, assessment preparation, certification, sustainment. Applies to all DIB sizes; requires SSP, evidence artifacts, annual affirmations, triennial recertification.
ISO 17025 Details
What It Is
ISO/IEC 17025:2017, titled "General requirements for the competence of testing and calibration laboratories," is an international accreditation standard. It ensures laboratories demonstrate competence, impartiality, and consistent operation for technically valid results. The risk-based, performance-oriented approach ties management controls to technical validity.
Key Components
- Eight sections: General (impartiality/confidentiality), Structural, Resource (personnel, equipment, traceability), Process (methods, uncertainty, reporting), Management System (Option A/B).
- Emphasizes metrological traceability, measurement uncertainty, method validation.
- Built on objectivity, continual improvement; accredited by ILAC-recognized bodies.
Why Organizations Use It
- Secures market access, regulatory acceptance of results.
- Mitigates risks from invalid data in safety-critical decisions.
- Enhances trust, competitiveness in global supply chains.
- Meets customer/regulatory demands for accredited competence.
Implementation Overview
- Phased: gap analysis, documentation, training, validation, proficiency testing, audits.
- Suits all lab sizes/industries globally.
- Involves accreditation assessments with witnessed technical activities.
