Requirements NIST SOURCE

Require that the issuance of [types of and/or specific authenticators] be conducted [one of: in person; by a trusted external party] before [registration authority] with authorization by [personnel or roles].

Discussion (NIST Supplemental Guidance)

Issuing authenticators in person or by a trusted external party enhances and reinforces the trustworthiness of the identity proofing process.

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-5(16) 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. types of and/or specific authenticators to be issued are defined;
  2. one of the following PARAMETER VALUES is selected: {in person; by a trusted external party};
  3. the registration authority that issues authenticators is defined;
  4. the personnel or roles who authorize the issuance of authenticators are defined;
  5. the issuance of <IA-05(16)_ODP[01] types of and/or specific authenticators> is required to be conducted <IA-05(16)_ODP[02] SELECTED PARAMETER VALUE> before <IA-05(16)_ODP[03] registration authority> with authorization by <IA-05(16)_ODP[04] personnel or roles>.

Examine

[SELECT FROM: Identification and authentication policy; procedures addressing identifier management; system security plan; system design documentation; mechanisms providing dynamic binding of identifiers and authenticators; system configuration settings and associated documentation; system audit records; other relevant documents or records].

Interview

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

Test

[SELECT FROM: Mechanisms supporting and/or implementing account management capability; mechanisms supporting and/or implementing identification and authentication management capabilities for the system].

STIGs & CCIs

No STIG checks or CCI mappings are currently loaded for IA-5(16). 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.
