Requirements NIST SOURCE

Employ guards to control [physical access points] to the facility where the system resides 24 hours per day, 7 days per week.

Discussion (NIST Supplemental Guidance)

Employing guards at selected physical access points to the facility provides a more rapid response capability for organizations. Guards also provide the opportunity for human surveillance in areas of the facility not covered by video surveillance.

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-3(3) 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. physical access points to the facility where the system resides are defined;
  2. guards are employed to control <PE-03(03)_ODP physical access points> to the facility where the system resides 24 hours per day, 7 days per week.

Examine

[SELECT FROM: Physical and environmental protection policy; procedures addressing physical access control; physical access control logs or records; physical access control devices; facility surveillance records; facility layout documentation; system entry and exit points; system security plan; other relevant documents or records].

Interview

[SELECT FROM: Organizational personnel with physical access control responsibilities; organizational personnel with information security responsibilities].

Test

[SELECT FROM: Organizational processes for physical access control to the facility where the system resides; mechanisms supporting and/or implementing physical access control for the facility where the system resides].

STIGs & CCIs

No STIG checks or CCI mappings are currently loaded for PE-3(3). 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.
