    NIST 800-171 Details

    What It Is

    NIST SP 800-171 Revision 3 is a U.S. government security framework for safeguarding Controlled Unclassified Information (CUI) confidentiality in nonfederal systems. It provides recommended requirements tailored from NIST SP 800-53 Moderate baseline, applicable via federal contracts like DFARS 252.204-7012. Focuses on components processing, storing, or transmitting CUI, using risk-based scoping.

    Key Components

    • 97 requirements (r3) across 17 families including Access Control, Audit, new Planning, Supply Chain Risk Management.
    • SSP and POA&M as core documentation artifacts.
    • SP 800-171A r3 for examine/interview/test assessments.
    • Tailoring via compensating controls and CUI enclaves.

    Why Organizations Use It

    • Mandatory for DoD contractors handling CUI/CDI.
    • Enables contract eligibility, CMMC Level 2 readiness.
    • Reduces breach risks, builds supply chain trust.
    • Strategic for federal market access, risk management.

    Implementation Overview

    • Phased: scoping, gap analysis, controls, evidence collection.
    • Applies to contractors, subcontractors; all sizes via enclaves.
    • Self or third-party assessments; SPRS scoring for DoD.

    AS9120B Details

    What It Is

    AS9120B is the official IAQG quality management system standard for aerospace distributors, built on ISO 9001:2015's 10-clause structure. It establishes requirements for organizations procuring, storing, splitting, and reselling parts without altering characteristics, using a risk-based approach to address distribution risks like traceability loss and counterfeits.

    Key Components

    • Over 100 aerospace-specific requirements beyond ISO 9001.
    • Core areas: context analysis, leadership, planning, support, operations (traceability, counterfeit prevention, supplier controls), performance evaluation, improvement.
    • Built on PDCA cycle; certification via accredited bodies with OASIS listing.

    Why Organizations Use It

    • Enables market access to OEMs/Tier 1 suppliers.
    • Mitigates risks of nonconformities, counterfeits, supply chain disruptions.
    • Builds customer trust, reduces liabilities, improves efficiency.
    • Strategic for ASD distributors seeking competitive edge.

    Implementation Overview

    • Phased: gap analysis, process design, training, audits (6-12 months).
    • Applies to aviation/space/defense distributors globally.
    • Requires internal audits, management reviews, Stage 1/2 certification audits.
