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 Withdrawn controls are retained for reference.

SC-15 · Collaborative Computing Devices and Applications

Control statement and discussion

NIST control statement

a. Prohibit remote activation of collaborative computing devices and applications with the following exceptions: [Assignment: exceptions where remote activation is to be allowed] ; and b. Provide an explicit indication of use to users physically present at the devices.

Discussion

Collaborative computing devices and applications include remote meeting devices and applications, networked white boards, cameras, and microphones. The explicit indication of use includes signals to users when collaborative computing devices and applications are activated.

SC-15(1) · Physical or Logical Disconnect

View parent control
Control statement and discussion

NIST control statement

Provide [Selection (one-or-more): physical; logical] disconnect of collaborative computing devices in a manner that supports ease of use.

Discussion

Failing to disconnect from collaborative computing devices can result in subsequent compromises of organizational information. Providing easy methods to disconnect from such devices after a collaborative computing session ensures that participants carry out the disconnect activity without having to go through complex and tedious procedures. Disconnect from collaborative computing devices can be manual or automatic.

View parent control
Control statement and discussion

NIST control statement

Disable or remove collaborative computing devices and applications from [Assignment: systems or system components] in [Assignment: secure work areas].

Discussion

Failing to disable or remove collaborative computing devices and applications from systems or system components can result in compromises of information, including eavesdropping on conversations. A Sensitive Compartmented Information Facility (SCIF) is an example of a secure work area.

SC-15(4) · Explicitly Indicate Current Participants

View parent control
Control statement and discussion

NIST control statement

Provide an explicit indication of current participants in [Assignment: online meetings and teleconferences].

Discussion

Explicitly indicating current participants prevents unauthorized individuals from participating in collaborative computing sessions without the explicit knowledge of other participants.
