Requirements NIST SOURCE

Employ and maintain automatic emergency lighting for the system that activates in the event of a power outage or disruption and that covers emergency exits and evacuation routes within the facility.

Discussion (NIST Supplemental Guidance)

The provision of emergency lighting applies primarily to organizational facilities that contain concentrations of system resources, including data centers, server rooms, and mainframe computer rooms. Emergency lighting provisions for the system are described in the contingency plan for the organization. If emergency lighting for the system fails or cannot be provided, organizations consider alternate processing sites for power-related contingencies.

Enhancements NIST SOURCE

PE-12(1) Essential Mission and Business Functions LOW MODERATE HIGH

Assessment

NIST SP 800-53A REV 5.2.0

Assessment Objectives

  1. automatic emergency lighting that activates in the event of a power outage or disruption is employed for the system;
  2. automatic emergency lighting that activates in the event of a power outage or disruption is maintained for the system;
  3. automatic emergency lighting for the system covers emergency exits within the facility;
  4. automatic emergency lighting for the system covers evacuation routes within the facility.

Examine

[SELECT FROM: Physical and environmental protection policy; procedures addressing emergency lighting; emergency lighting documentation; emergency lighting test records; emergency exits and evacuation routes; system security plan; other relevant documents or records].

Interview

[SELECT FROM: Organizational personnel with the responsibility for emergency lighting and/or planning; organizational personnel with information security responsibilities].

Test

[SELECT FROM: Mechanisms supporting and/or implementing an emergency lighting capability].

Overlays

STIGs & CCIs

No STIG checks or CCI mappings are currently loaded for PE-12. 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.
