    International standard for business continuity management systems

    Quick Verdict

    CMMC mandates cybersecurity certification for DoD contractors protecting FCI/CUI, while ISO 22301 is a voluntary standard for business continuity resilience across all sectors. Organizations adopt CMMC for contract eligibility; ISO 22301 for disruption recovery and trust.

    CMMC Details

    What It Is

    Cybersecurity Maturity Model Certification (CMMC) 2.0 is a DoD certification program ensuring cybersecurity protections for Federal Contract Information (FCI) and Controlled Unclassified Information (CUI) across the Defense Industrial Base (DIB). It employs a tiered, cumulative model with three levels using risk-based scoping and NIST-mapped requirements.

    Key Components

    • 14 domains (e.g., Access Control, Incident Response) with 17 practices (Level 1), 110 (Level 2 from NIST SP 800-171 Rev 2), plus 24 enhancements (Level 3 from NIST SP 800-172).
    • Assessments via self-assessment, C3PAO (Level 2), or DIBCAC (Level 3), with SPRS/eMASS reporting and limited POA&Ms (180-day closure).

    Why Organizations Use It

    Mandated for DoD contracts to avoid ineligibility; reduces supply chain risks, breach costs, and enhances bid competitiveness. Builds resilience, trust, and aligns with broader NIST frameworks.

    Implementation Overview

    Phased approach: governance, scoping/gap analysis, remediation, pre-assessment, certification, sustainment. Targets all DIB primes/subcontractors; triennial validity requires annual affirmations. (178 words)

    ISO 22301 Details

    What It Is

    ISO 22301:2019 is the international standard specifying requirements for a Business Continuity Management System (BCMS). It enables organizations to protect against, reduce the likelihood of, and recover from disruptive incidents. The standard uses a risk-based PDCA (Plan-Do-Check-Act) cycle for systematic resilience building.

    Key Components

    • 10 clauses (4-10 core): context of organization, leadership, planning (BIA, risk assessment), support, operation, performance evaluation, improvement.
    • Defines terms like RTO, MTPD; built on Annex SL high-level structure.
    • Certification model: 3-year validity with annual surveillance audits.

    Why Organizations Use It

    Drives resilience, reduces downtime and losses, ensures compliance (e.g., NIS Directive, NIST), enhances stakeholder trust, provides competitive edges like procurement advantages and lower insurance premiums.

    Implementation Overview

    Gap analysis, BIA, recovery strategies, training, testing, audits. Suits all sizes/sectors globally; certification via two-stage process (6-8 weeks).
