Requirements NIST SOURCE

Require that the presented identity evidence be validated and verified through [methods of validation and verification].

Discussion (NIST Supplemental Guidance)

Validation and verification of identity evidence increases the assurance that accounts and identifiers are being established for the correct user and authenticators are being bound to that user. Validation refers to the process of confirming that the evidence is genuine and authentic, and the data contained in the evidence is correct, current, and related to an individual. Verification confirms and establishes a linkage between the claimed identity and the actual existence of the user presenting the evidence. Acceptable methods for validating and verifying identity evidence are consistent with the risks to the systems, roles, and privileges associated with the users 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(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. methods of validation and verification of identity evidence are defined;
  2. the presented identity evidence is validated and verified through <IA-12(03)_ODP methods of validation and verification>.

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].

Overlays

STIGs & CCIs

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