NIST SP 800 53 Revision 5 includes a staggering 1,189 controls, divided into the following 20 control families:
This NIST SP 800-53 R5 control count includes deprecated controls that have been removed or rolled into other controls.
NIST SP 800-53B breaks most of those controls into low, moderate, high and privacy baselines. However, there are many NIST SP 800-53 R5 controls that are not otherwise categorized and are therefore not part of a baseline.
ComplianceForge has 1-1 matching for NIST SP 800-53 R5 families and controls in its NIST SP 800-53 R5 Cybersecurity & Data Protection Program (CDPP) documentation.
