Limit access using physical barriers.

Discussion (NIST Supplemental Guidance)

Physical barriers include bollards, concrete slabs, jersey walls, and hydraulic active vehicle barriers.

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(7) 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 barriers are used to limit access.

Examine

[SELECT FROM: Physical and environmental protection policy; procedures addressing physical access control; list of physical barriers to limit access to the system; system security plan; other relevant documents or records].

Interview

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

Overlays

Showing the OT/ICS overlay for the parent control PE-3 — see the PE-3(7) entries within each baseline below.

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

  • Base control: Included (matches standard baseline)

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-3(7). 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.
