NIST 800-171 R2 to R3 Transition Guide
Sooner, rather than later, the US Government's global supply chain will have to transition to NIST 800-171 R3. ComplianceForge provides a free resource for organizations migrating from NIST 800-171 R2 to R3. This guide provides an Assessment Objective (AO)-level analysis to address differences:
- Over 1/3 are minimal effort (clear, direct mapping)
- Approximately 1/5 are moderate effort (indirect mapping)
- Approximately 1/2 are significant effort (no clear mapping or new AOs)
This guide also addresses the logical dependencies that exist from "orphaned AOs" that are not in NIST 800-171A R3, but a requirement to demonstrate evidence of due diligence and due care still exists for specific functions (e.g., maintenance operations, roles & responsibilities, inventories, physical security, etc.).
