Requirements NIST SOURCE

Coordinate with the following external organizations for cross-organization management of identifiers: [external organizations].

Discussion (NIST Supplemental Guidance)

Cross-organization identifier management provides the capability to identify individuals, groups, roles, or devices when conducting cross-organization activities involving the processing, storage, or transmission of information.

Implementation Guidance

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-4(6) 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. external organizations with whom to coordinate the cross-organization management of identifiers are defined;
  2. cross-organization management of identifiers is coordinated with <IA-04(06)_ODP external organizations>.

Examine

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

Interview

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

Test

[SELECT FROM: Mechanisms supporting and/or implementing identifier management].

Overlays

STIGs & CCIs

No STIG checks or CCI mappings are currently loaded for IA-4(6). 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.
