    NIST 800-171 Details

    What It Is

    NIST SP 800-171 Revision 3 is a U.S. government framework providing recommended security requirements to protect Controlled Unclassified Information (CUI) confidentiality in nonfederal systems. Its primary scope targets federal contractors and supply chains, using a control-based approach tailored from NIST SP 800-53 Moderate baseline, emphasizing scoping to CUI-processing components.

    Key Components

    • 17 families (expanded from 14 in r2) like Access Control, Audit, Supply Chain Risk Management.
    • ~97-110 requirements with Organization-Defined Parameters (ODPs).
    • Built on FIPS 200 and SP 800-53; includes SSP, POA&M, and SP 800-171A assessments (examine/interview/test).
    • Compliance via self-assessment or third-party (e.g., CMMC Level 2).

    Why Organizations Use It

    • Meets DFARS 252.204-7012 mandates for DoD contracts.
    • Reduces breach risks, ensures procurement eligibility.
    • Builds stakeholder trust, competitive edge in federal markets.

    Implementation Overview

    Phased: scope CUI enclave, gap analysis, implement controls (MFA, SIEM), document SSP/POA&M. Applies to contractors handling CUI; audits via SPRS/CMMC. Timelines 6-36 months based on size.

    ISO 30301 Details

    What It Is

    ISO 30301:2019 (Information and documentation — Management systems for records — Requirements) is an international certifiable standard for establishing a Management System for Records (MSR). It applies to any organization, using a High-Level Structure (HLS) for governance (Clauses 4–10) combined with records-specific operational controls (Clause 8 and Annex A), focusing on creating reliable evidence of business activities through risk-based planning.

    Key Components

    • **Six core clausesContext, Leadership, Planning, Support, Operation, Performance evaluation, Improvement.
    • **Normative Annex AOperational controls for records lifecycle.
    • Built on ISO 15489 principles (authenticity, reliability, usability).
    • Flexible conformity: self-declaration, external confirmation, or third-party certification.

    Why Organizations Use It

    • Ensures compliance, auditability, and transparency.
    • Mitigates risks like data loss or legal failures.
    • Improves efficiency in retrieval and disposition.
    • Builds stakeholder trust via certifiable governance.

    Implementation Overview

    • Phased: gap analysis, policy design, operational rollout, audits.
    • Scalable for any size/sector; 12-18 months typical.
    • Involves cross-functional teams, training, system integration.
