SP 800-53 Rev 5 — Control Families Quick Reference

These are the 20 control families. Each has a dedicated reference file.

CSF 2.0 — Functions Quick Reference

Common Tasks

Find controls for a specific topic

1. Identify the relevant control family from the table above
2. Load the family reference file (e.g., references/800-53/ac.md for Access Control)
3. Search for the specific control by ID or keyword

Compare FedRAMP baselines

1. Load references/cross-references/baselines.md
2. Look up Low, Moderate, or High baseline control selections
3. Cross-reference with specific control family files for details

Map 800-53 controls to CSF

1. Load references/cross-references/800-53-to-csf.md
2. Find the CSF function/category of interest
3. See which 800-53 controls implement that category

Map 800-53 to 800-171

1. Load references/cross-references/800-53-to-800-171.md
2. Find the 800-53 control of interest
3. See the corresponding 800-171 requirement (if any)

Look up related controls

1. Load the family reference file (e.g., references/800-53/ac.md)
2. Each non-withdrawn control has a **Related Controls:** line listing cross-references
3. These are sourced from the authoritative NIST OSCAL catalog

Check baseline applicability

1. Each non-withdrawn control has a **Baselines:** line showing Low, Moderate, and/or High
2. For a full listing: python scripts/lookup.py baseline moderate (or low, high)
3. Filter by family: python scripts/lookup.py baseline moderate AC
4. See also references/cross-references/baselines.md for FedRAMP details

Map CSF 2.0 to 800-53 controls

1. By function: python scripts/lookup.py map csf PR (shows all Protect mappings)
2. By category: python scripts/lookup.py map csf PR.AA (shows specific category)
3. Or load references/cross-references/800-53-to-csf.md directly

Look up assessment procedures

1. Identify the control from 800-53
2. Load the corresponding family file under references/800-53a/
3. Find the assessment objectives and methods

Understand a NIST term

1. Load references/glossary.md
2. Search for the term alphabetically

Usage Notes

• Control IDs follow the pattern: {FAMILY}-{NUMBER} (e.g., AC-2, SI-4)
• Enhancements append a parenthetical: AC-2(1), SI-4(5)
• Baselines: Low ⊂ Moderate ⊂ High (each higher baseline includes all controls from lower ones). Each control in 800-53 files has a **Baselines:** tag showing which baselines include it.
• Related Controls: Every non-withdrawn control has a **Related Controls:** line sourced from the NIST OSCAL catalog.
• 800-171 requirements map to a subset of 800-53 Moderate baseline controls
• CSF categories use dot notation: GV.OC-01, PR.AC-01
• OSCAL (Open Security Controls Assessment Language) provides machine-readable versions of these frameworks
