Requirements NIST SOURCE

Require that the validation and verification of identity evidence be conducted in person before a designated registration authority.

Discussion (NIST Supplemental Guidance)

In-person proofing reduces the likelihood of fraudulent credentials being issued because it requires the physical presence of individuals, the presentation of physical identity documents, and actual face-to-face interactions with designated registration authorities.

Engineering Interpretation

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

No engineering interpretation has been authored for IA-12(4) 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 validation and verification of identity evidence is conducted in person before a designated registration authority.

Examine

[SELECT FROM: Identification and authentication policy; procedures addressing identity proofing; system security plan; other relevant documents or records].

Interview

[SELECT FROM: Organizational personnel with system operations responsibilities; organizational personnel with information security responsibilities; system/network administrators; system developers; organizational personnel with identification and authentication responsibilities].

Test

[SELECT FROM: Mechanisms supporting and/or implementing identification and authentication capabilities].

STIGs & CCIs

No STIG checks or CCI mappings are currently loaded for IA-12(4). 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.
