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 Withdrawn controls are retained for reference.
Require that users log out when [Assignment: time period of expected inactivity or description of when to log out].
Discussion
Inactivity logout is behavior- or policy-based and requires users to take physical action to log out when they are expecting inactivity longer than the defined period. Automatic enforcement of inactivity logout is addressed by [AC-11](#ac-11).

Control statement and discussion
NIST control statement
a. Prevent further access to the system by [Selection (one-or-more): initiating a device lock after [Assignment: time period] of inactivity; requiring the user to initiate a device lock before leaving the system unattended] ; and
b. Retain the device lock until the user reestablishes access using established identification and authentication procedures.
Discussion
Device locks are temporary actions taken to prevent logical access to organizational systems when users stop work and move away from the immediate vicinity of those systems but do not want to log out because of the temporary nature of their absences. Device locks can be implemented at the operating system level or at the application level. A proximity lock may be used to initiate the device lock (e.g., via a Bluetooth-enabled device or dongle). User-initiated device locking is behavior or policy-based and, as such, requires users to take physical action to initiate the device lock. Device locks are not an acceptable substitute for logging out of systems, such as when organizations require users to log out at the end of workdays.

Conceal, via the device lock, information previously visible on the display with a publicly viewable image.
Discussion
The pattern-hiding display can include static or dynamic images, such as patterns used with screen savers, photographic images, solid colors, clock, battery life indicator, or a blank screen with the caveat that controlled unclassified information is not displayed.
