Verify that individuals accessing a system processing, storing, or transmitting information requiring special protection:

Discussion (NIST Supplemental Guidance)

Organizational information that requires special protection includes controlled unclassified information. Personnel security criteria include position sensitivity background screening requirements.

Engineering Interpretation

Original engineering commentary written for this explorer — not NIST source text and not authoritative guidance.

No engineering interpretation has been authored for PS-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. additional personnel screening criteria to be satisfied for individuals accessing a system processing, storing, or transmitting information requiring special protection are defined;
  2. individuals accessing a system processing, storing, or transmitting information requiring special protection have valid access authorizations that are demonstrated by assigned official government duties;
  3. individuals accessing a system processing, storing, or transmitting information requiring special protection satisfy <PS-03(03)_ODP additional personnel screening criteria>.

Examine

[SELECT FROM: Personnel security policy; access control policy, procedures addressing personnel screening; records of screened personnel; screening criteria; records of access authorizations; system security plan; other relevant documents or records].

Interview

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

Test

[SELECT FROM: Organizational processes for ensuring valid access authorizations for information requiring special protection; organizational process for additional personnel screening for information requiring special protection].

STIGs & CCIs

No STIG checks or CCI mappings are currently loaded for PS-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.
