PE-14: TEMPERATURE AND HUMIDITY CONTROLs
TAILORED FOR INDUSTRIAL CONTROL SYSTEMS
ICS Control Baselines:
- Low
- Moderate
- High
The organization:
- a. Maintains temperature and humidity levels within the facility where the information system resides at [Assignment: organization-defined acceptable levels]; and
- b. Monitors temperature and humidity levels [Assignment: organization-defined frequency].
SUPPLEMENTAL GUIDANCE
This control applies primarily to facilities containing concentrations of information system resources, for example, data centers, server rooms, and mainframe computer rooms.
ICS SUPPLEMENTAL GUIDANCE
Temperature and humidity controls are typically components of other ICS systems such as the HVAC, process, or lighting systems, or can be a standalone and unique ICS system. ICS can operate in extreme environments and both interior and exterior locations. For a specific ICS, the temperature and humidity design and operational parameters dictate the performance specifications. As ICS and IS become interconnected and the network provides connectivity across the hybrid domain, power circuits, distribution closets, routers and switches that support fire protection and life safety systems must be maintained at the proper temperature and humidity.
RELATED CONTROLS: PE-14
CONTROL ENHANCEMENTS
PE-14 (1) TEMPERATURE AND HUMIDITY CONTROLS | AUTOMATIC CONTROLS
NOT SELECTED FOR THE NIST ISC CONTROL SET
The organization employs automatic temperature and humidity controls in the facility to prevent fluctuations potentially harmful to the information system.
Supplemental Guidance: NONE
PE-14 (2) TEMPERATURE AND HUMIDITY CONTROLS | MONITORING WITH ALARMS / NOTIFICATIONS
NOT SELECTED FOR THE NIST ISC CONTROL SET
The organization employs temperature and humidity monitoring that provides an alarm or notification of changes potentially harmful to personnel or equipment.
Supplemental Guidance: NONE
