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.
