Requirements NIST SOURCE

Enforce physical access authorizations to the system in addition to the physical access controls for the facility at [physical spaces].

Discussion (NIST Supplemental Guidance)

Control of physical access to the system provides additional physical security for those areas within facilities where there is a concentration of system components.

Implementation Guidance

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(1) 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 spaces containing one or more components of the system are defined;
  2. physical access authorizations to the system are enforced;
  3. physical access controls are enforced for the facility at <PE-03(01)_ODP physical spaces>.

Examine

[SELECT FROM: Physical and environmental protection policy; procedures addressing physical access control; physical access control logs or records; physical access control devices; access authorizations; access credentials; system entry and exit points; list of areas within the facility containing concentrations of system components or system components requiring additional physical protection; system security plan; other relevant documents or records].

Interview

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

Test

[SELECT FROM: Organizational processes for physical access control to the information system/components; mechanisms supporting and/or implementing physical access control for facility areas containing system components].

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.

STIGs & CCIs

No STIG checks or CCI mappings are currently loaded for PE-3(1). 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.
