Requirements NIST SOURCE

Require evidence of individual identification be presented to the registration authority.

Discussion (NIST Supplemental Guidance)

Identity evidence, such as documentary evidence or a combination of documents and biometrics, reduces the likelihood of individuals using fraudulent identification to establish an identity or at least increases the work factor of potential adversaries. The forms of acceptable evidence are consistent with the risks to the systems, roles, and privileges associated with the user’s account.

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(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. evidence of individual identification is presented to the 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(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.
