Requirements NIST SOURCE

Manage individual identifiers by uniquely identifying each individual as [characteristics].

Discussion (NIST Supplemental Guidance)

Characteristics that identify the status of individuals include contractors, foreign nationals, and non-organizational users. Identifying the status of individuals by these characteristics provides additional information about the people with whom organizational personnel are communicating. For example, it might be useful for a government employee to know that one of the individuals on an email message is a contractor.

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(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. characteristics used to identify individual status is defined;
  2. individual identifiers are managed by uniquely identifying each individual as <IA-04(04)_ODP characteristics>.

Examine

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

Interview

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

Test

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

STIGs & CCIs

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