Overlays
An overlay tailors the standard NIST SP 800-53 baselines for a specific technology domain or mission — adding, removing, or otherwise adjusting which controls and enhancements apply.
OT/ICS Overlay
AUTHORITATIVE — SP 800-82r3Sourced directly from NIST SP 800-82r3, Appendix F, Table 22 — the baseline tailoring NIST publishes for Operational Technology and Industrial Control Systems. This is the one overlay with real, sourced data loaded in this explorer. It covers 228 controls across 19 families, each with LOW/MODERATE/HIGH OT baseline selections diffed against the standard SP 800-53 baseline.

Other Overlays
The data model supports additional overlays (e.g. Privacy, High Value Asset), but no authoritative source data for them is loaded in this repository yet — so none are shown here rather than guessing at their content.
