NIST SP 800-53 Rev. 5 PE-15 — Water Damage Protection

What this control requires

Protect systems from water leakage damage by installing accessible, functional master shutoff or isolation valves, known to key personnel, in facilities like data centers or server rooms to ensure rapid response to water-related incidents. This control supports the Master Shutoff Valve System capability within the Physical and Environmental Protection family.

In plain English

Protect systems from water leakage damage by installing accessible, functional master shutoff or isolation valves, known to key personnel, in facilities like data centers or server rooms to ensure rapid response to water-related incidents. In practice, this means you can prove you data management-level controls on a defined cadence.

Why it matters

SP 800-53 is the catalogue every U.S. federal authorisation (FedRAMP, FISMA, CMMC) and most regulated industries point at. A missing control surfaces as a Plan of Action & Milestones (POA&M) item that an Authorizing Official must approve before the Authority To Operate is granted or renewed.

This control is rated high. Auditors expect a named owner, a remediation SLA, and a tooling artefact that evidences continuous operation.

What an auditor looks for

A 3PAO (FedRAMP) or Independent Assessor (NIST RMF) tests against NIST SP 800-53A assessment procedures. For each control they expect a documented implementation that addresses every assessment objective (Examine, Interview, Test) and an implementation summary in the System Security Plan.

Within Physical and Environmental Protection, the assessor will trace your implementation back to the catalogue reference (Control PE-15) and look for objective evidence on the latest two assessment cycles.

How to implement

Incident Response

Runbook. Maintain a runbook keyed by incident type with named roles (IC, comms, scribe), an out-of-band comms channel, and a 72-hour timeline for external notification.

Tabletop. Run a quarterly tabletop exercise (ransomware, insider, supply-chain) and feed gaps back into the runbook.

Operational checklist

• Data. Document the trigger, the owner and the cadence.
• Physical. Document the trigger, the owner and the cadence.
• Protection. Document the trigger, the owner and the cadence.
• Environmental. Document the trigger, the owner and the cadence.
• Response. Document the trigger, the owner and the cadence.
• Scope: management, system, personnel, incidents, protection, capability, systems, server rooms.

Evidence to collect

• Ticketing Workflow. ticketing_workflow evidence

Workflow metrics (ServiceNow, Jira) show approvals and remediation. Focus: Water Damage Protection.

Common pitfalls

• Runbooks that name a role but no person, or list a paging channel that no longer exists.

How it maps to other frameworks

Computed from shared tags, control component and key-operation subjects — handy when you are reconciling controls across an audit.
