NIST SP 800-53 Rev. 5 PE-10 — Emergency Shutoff

What this control requires

The capability to shut off power to specified systems or system components in emergency situations. Emergency shutoff switches or devices must be placed in accessible locations for authorized personnel and should be protected from unauthorized activation to ensure safety and prevent damage during emergencies. This control supports the Emergency Power Shutoff capability within the Physical and Environmental Protection family.

In plain English

The capability to shut off power to specified systems or system components in emergency situations. In practice, this means you can prove you security system-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 critical in the source catalogue. Treat gaps here as production incidents in the risk register, not housekeeping.

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-10) and look for objective evidence on the latest two assessment cycles.

How to implement

Endpoint Protection

MDM. Make MDM enrollment a hard gate for device access (Intune compliance + Conditional Access, or Jamf + Okta device trust). Unmanaged devices simply don't get a session token.

EDR. Deploy CrowdStrike / SentinelOne / Defender for Endpoint to every server and laptop; alert on any host that stops sending telemetry for >24h.

Operational checklist

• Security. 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.
• Unauthorized. Document the trigger, the owner and the cadence.
• Scope: system, personnel, controls, protection, components, capability, systems, shutoff.

Evidence to collect

• User Device Scan. MDM compliance state per user device (Intune / Jamf / Workspace ONE).

Endpoint compliance telemetry (Intune, Jamf) proves managed coverage. Focus: Emergency Shutoff.

Common pitfalls

• Pilot MDM rollouts that quietly exclude executives or engineers; carving out the highest-risk users is the most common audit failure.
