PE-9: POWER EQUIPMENT AND CABLING
TAILORED FOR INDUSTRIAL CONTROL SYSTEMS
ICS Control Baselines:
- Moderate
- High
The organization protects power equipment and power cabling for the information system from damage and destruction.
SUPPLEMENTAL GUIDANCE
Organizations determine the types of protection necessary for power equipment and cabling employed at different locations both internal and external to organizational facilities and environments of operation. This includes, for example, generators and power cabling outside of buildings, internal cabling and uninterruptable power sources within an office or data center, and power sources for self-contained entities such as vehicles and satellites.
ICS SUPPLEMENTAL GUIDANCE
No ICS Supplemental Guidance.
- PE-4 — PHYSICAL AND ENVIRONMENTAL PROTECTION | ACCESS CONTROL FOR TRANSMISSION MEDIUM
PE-9 (1) POWER EQUIPMENT AND CABLING | REDUNDANT CABLING
ICS Control Baselines:
- Moderate (ADDED)
- High (ADDED)
The organization employs redundant power cabling paths that are physically separated by [Assignment: organization-defined distance].
Supplemental Guidance:
Physically separate, redundant power cables help to ensure that power continues to flow in the event one of the cables is cut or otherwise damaged.
No ICS Supplemental Guidance.
Rationale (for adding PE-9 (1): Continuity of ICS control and operation requires redundant power cabling.
PE-9 (2) POWER EQUIPMENT AND CABLING | AUTOMATIC VOLTAGE CONTROLS
NOT SELECTED FOR THE NIST ISC CONTROL SET
The organization employs automatic voltage controls for [Assignment: organization-defined critical information system components].
Supplemental Guidance: NONE
