NIST SP 800-53 Rev. 5 Common Control Library

Browse 1,193 controls and enhancements across 20 security and privacy families. Use the GovRAMP crosswalk to locate controls referenced by Security Snapshot, Core, and Moderate.

A shared catalog supports common-control planning; designation as a common, hybrid, or system-specific control depends on your organization’s implementation and inheritance decisions.

NIST OSCAL content 5.1.1+u4, retrieved 2026-09-18. GovRAMP Snapshot v1.4 and Core selection from Moderate v1.06 reference the December 2020 Rev. 5 text. Mappings establish exact identifier correspondence, not identical requirements, inherited implementation, or GovRAMP authorization. GovRAMP parameters and additional requirements remain authoritative for each program. Full Moderate, High, and other programs are not mapped here. Withdrawn controls are retained for reference.

SI-6 · Security and Privacy Function Verification

Control statement and discussion

NIST control statement

a. Verify the correct operation of [Assignment: organization-defined security and privacy functions]; b. Perform the verification of the functions specified in SI-6a [Selection (one-or-more): [Assignment: system transitional states] ; upon command by user with appropriate privilege; [Assignment: frequency] ]; c. Alert [Assignment: personnel or roles] to failed security and privacy verification tests; and d. [Selection (one-or-more): shut the system down; restart the system; [Assignment: alternative action(s)] ] when anomalies are discovered.

Discussion

Transitional states for systems include system startup, restart, shutdown, and abort. System notifications include hardware indicator lights, electronic alerts to system administrators, and messages to local computer consoles. In contrast to security function verification, privacy function verification ensures that privacy functions operate as expected and are approved by the senior agency official for privacy or that privacy attributes are applied or used as expected.
