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 Withdrawn controls are retained for reference.

Control statement and discussion
NIST control statement
Provide an uninterruptible power supply to facilitate [Selection (one): an orderly shutdown of the system; transition of the system to long-term alternate power] in the event of a primary power source loss.
Discussion
An uninterruptible power supply (UPS) is an electrical system or mechanism that provides emergency power when there is a failure of the main power source. A UPS is typically used to protect computers, data centers, telecommunication equipment, or other electrical equipment where an unexpected power disruption could cause injuries, fatalities, serious mission or business disruption, or loss of data or information. A UPS differs from an emergency power system or backup generator in that the UPS provides near-instantaneous protection from unanticipated power interruptions from the main power source by providing energy stored in batteries, supercapacitors, or flywheels. The battery duration of a UPS is relatively short but provides sufficient time to start a standby power source, such as a backup generator, or properly shut down the system.

PE-11(1) · Alternate Power Supply — Minimal Operational Capability
Provide an alternate power supply for the system that is activated [Selection (one): manually; automatically] and that can maintain minimally required operational capability in the event of an extended loss of the primary power source.
Discussion
Provision of an alternate power supply with minimal operating capability can be satisfied by accessing a secondary commercial power supply or other external power supply.

PE-11(2) · Alternate Power Supply — Self-contained
Provide an alternate power supply for the system that is activated [Selection (one): manually; automatically] and that is:
(a) Self-contained;
(b) Not reliant on external power generation; and
(c) Capable of maintaining [Selection (one): minimally required operational capability; full operational capability] in the event of an extended loss of the primary power source.
Discussion
The provision of a long-term, self-contained power supply can be satisfied by using one or more generators with sufficient capacity to meet the needs of the organization.
