Requirements NIST SOURCE

Perform security checks [frequency] at the physical perimeter of the facility or system for exfiltration of information or removal of system components.

Discussion (NIST Supplemental Guidance)

Organizations determine the extent, frequency, and/or randomness of security checks to adequately mitigate risk associated with exfiltration.

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(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. the frequency at which to perform security checks at the physical perimeter of the facility or system for exfiltration of information or removal of system components is defined;
  2. security checks are performed <PE-03(02)_ODP frequency> at the physical perimeter of the facility or system for exfiltration of information or removal of system components.

Examine

[SELECT FROM: Physical and environmental protection policy; procedures addressing physical access control; physical access control logs or records; records of security checks; security audit reports; security inspection reports; 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 and/or system; mechanisms supporting and/or implementing physical access control for the facility or system; mechanisms supporting and/or implementing security checks for the unauthorized exfiltration of information].

STIGs & CCIs

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