NIST 800-171
U.S. standard protecting CUI confidentiality in nonfederal systems
ISO 22000
International standard for food safety management systems
Quick Verdict
NIST 800-171 safeguards CUI confidentiality for defense contractors via contractual controls, while ISO 22000 establishes FSMS for food chain organizations using HACCP and PRPs. Companies adopt NIST for DoD compliance; ISO for global market access and safety assurance.

NIST 800-171 Details
What It Is
NIST SP 800-171 Revision 3 is a U.S. government framework providing security requirements to protect Controlled Unclassified Information (CUI) confidentiality in nonfederal systems. Its primary scope targets contractors handling CUI via contracts, using a control-based approach tailored from SP 800-53 Moderate baseline.
Key Components
- Organized into 17 families (e.g., Access Control, Audit, Supply Chain Risk Management) with ~98 requirements.
- Built on FIPS 200 and SP 800-53; includes SP 800-171A for assessments.
- Compliance via System Security Plan (SSP) and POA&M; supports tailoring and equivalencies.
Why Organizations Use It
- Mandatory for DoD via DFARS 252.204-7012; enables contract eligibility.
- Reduces breach risks, enhances resilience; builds stakeholder trust.
- Competitive edge in federal supply chains.
Implementation Overview
- Phased: scoping, gap analysis, SSP/POA&M, controls, monitoring.
- Applies to contractors any size; audits via self or third-party (e.g., CMMC).
ISO 22000 Details
What It Is
ISO 22000:2018 is the international standard for Food Safety Management Systems (FSMS). It provides a certifiable framework for organizations in the food chain to ensure safe products through systematic hazard control. Its risk-based approach integrates HACCP principles with management system discipline using the High-Level Structure (HLS) and dual PDCA cycles.
Key Components
- Clauses 4-10 cover context, leadership, planning, support, operation, evaluation, and improvement.
- Core elements: PRPs, hazard analysis, CCPs/OPRPs, traceability, verification, and communication.
- Built on Codex HACCP and HLS for integration.
- Voluntary certification via accredited bodies.
Why Organizations Use It
- Meets regulatory/customer requirements and enables market access (e.g., GFSI schemes).
- Reduces risks of recalls, contamination, and liability.
- Builds trust with stakeholders, improves efficiency, and supports integration with ISO 9001/14001.
Implementation Overview
- Phased: gap analysis, PRPs/hazard plans, training, audits.
- Applies to all food chain organizations; scalable by size.
- Certification involves stage 1/2 audits, annual surveillance.
