Discussion (NIST Supplemental Guidance)

Emergency power shutoff primarily applies to organizational facilities that contain concentrations of system resources, including data centers, mainframe computer rooms, server rooms, and areas with computer-controlled machinery.

Engineering Interpretation

Original engineering commentary written for this explorer — not NIST source text and not authoritative guidance.

No engineering interpretation has been authored for PE-10 yet. This section is architected to receive it — see the Requirements and Assessment sections above for the authoritative NIST source content in the meantime.

Assessment

NIST SP 800-53A REV 5.2.0

Assessment Objectives

  1. system or individual system components that require the capability to shut off power in emergency situations is/are defined;
  2. location of emergency shutoff switches or devices by system or system component is defined;
  3. the capability to shut off power to <PE-10_ODP[01] system or individual system components> in emergency situations is provided;
  4. emergency shutoff switches or devices are placed in <PE-10_ODP[02] location> to facilitate access for authorized personnel;
  5. the emergency power shutoff capability is protected from unauthorized activation.

Examine

[SELECT FROM: Physical and environmental protection policy; procedures addressing power source emergency shutoff; emergency shutoff controls or switches; locations housing emergency shutoff switches and devices; security safeguards protecting the emergency power shutoff capability from unauthorized activation; system security plan; other relevant documents or records].

Interview

[SELECT FROM: Organizational personnel with the responsibility for the emergency power shutoff capability (both implementing and using the capability); organizational personnel with information security responsibilities].

Test

[SELECT FROM: Mechanisms supporting and/or implementing emergency power shutoff].

Overlays

OT/ICS Overlay SP 800-82r3

NIST SP 800-82r3 Appendix F, Table 22. Blank baseline means the control/control enhancement is not selected in that initial OT baseline.

LOW

Not applicable at this tier.

MODERATE

  • Base control: Included (matches standard baseline)

HIGH

  • Base control: Included (matches standard baseline)

STIGs & CCIs

No STIG checks or CCI mappings are currently loaded for PE-10. This section is architected to display, per product: STIG ID, Finding ID, Severity, Title, Description, Check, Fix, CCI, and NIST control mapping — but nothing is populated here until a real DISA STIG/CCI dataset is ingested.
