PE-15: WATER DAMAGE PROTECTION

TAILORED FOR INDUSTRIAL CONTROL SYSTEMS

  • ICS Control Baselines:
  • Low
  • Moderate
  • High

The organization protects the information system from damage resulting from water leakage by providing master shutoff or isolation valves that are accessible, working properly, and known to key personnel.

SUPPLEMENTAL GUIDANCE

This control applies primarily to facilities containing concentrations of information system resources including, for example, data centers, server rooms, and mainframe computer rooms. Isolation valves can be employed in addition to or in lieu of master shutoff valves to shut off water supplies in specific areas of concern, without affecting entire organizations.

ICS SUPPLEMENTAL GUIDANCE

Water damage protection and use of shutoff and isolation valves is both a procedural action, and also a specific type of ICS. ICS that are used in the manufacturing, hydropower, transportation/navigation, water and wastewater industries rely on the movement of water and are specifically designed to manage the quantity/flow and pressure of water. 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 should ensure that water will not disable the system (e.g. a fire that activates the sprinkler system does not spray onto the fire control servers, router, switches and short out the alarms, egress systems, emergency lighting, and suppression systems).

CONTROL ENHANCEMENTS

PE-15 (1) WATER DAMAGE PROTECTION | AUTOMATION SUPPORT
  • ISC Control Baseline:
  • High

The organization employs automated mechanisms to detect the presence of water in the vicinity of the information system and alerts [Assignment: organization-defined personnel or roles].

Supplemental Guidance:

Automated mechanisms can include, for example, water detection sensors, alarms, and notification systems.

No ICS Supplemental Guidance.
