Requirements NIST SOURCE

Employ environmental control monitoring that provides an alarm or notification of changes potentially harmful to personnel or equipment to [personnel or roles].

Discussion (NIST Supplemental Guidance)

The alarm or notification may be an audible alarm or a visual message in real time to personnel or roles defined by the organization. Such alarms and notifications can help minimize harm to individuals and damage to organizational assets by facilitating a timely incident response.

Engineering Interpretation

No engineering interpretation has been authored for PE-14(2) 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. personnel or roles to be notified by environmental control monitoring when environmental changes are potentially harmful to personnel or equipment is/are defined;
  2. environmental control monitoring is employed;
  3. the environmental control monitoring capability provides an alarm or notification to <PE-14(02)_ODP personnel or roles> when changes are potentially harmful to personnel or equipment.

Examine

[SELECT FROM: Physical and environmental protection policy; procedures addressing temperature and humidity monitoring; facility housing the system; logs or records of temperature and humidity monitoring; records of changes to temperature and humidity levels that generate alarms or notifications; system security plan; other relevant documents or records].

Interview

[SELECT FROM: Organizational personnel with responsibilities for system environmental controls; organizational personnel with information security responsibilities].

Test

[SELECT FROM: Mechanisms supporting and/or implementing temperature and humidity monitoring].

HIGH

  • Base control: Included (matches standard baseline)

STIGs & CCIs

No STIG checks or CCI mappings are currently loaded for PE-14(2). 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.
