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 Withdrawn controls are retained for reference.

Control statement and discussion

NIST control statement

Protect power equipment and power cabling for the system from damage and destruction.

Discussion

Organizations determine the types of protection necessary for the power equipment and cabling employed at different locations that are both internal and external to organizational facilities and environments of operation. Types of power equipment and cabling include internal cabling and uninterruptable power sources in offices or data centers, generators and power cabling outside of buildings, and power sources for self-contained components such as satellites, vehicles, and other deployable systems.

PE-9(1) · Redundant Cabling

View parent control
Control statement and discussion

NIST control statement

Employ redundant power cabling paths that are physically separated by [Assignment: distance].

Discussion

Physically separate and redundant power cables ensure that power continues to flow in the event that one of the cables is cut or otherwise damaged.
