Requirements NIST SOURCE

Maintain the attributes for each uniquely identified individual, device, or service in [protected central storage].

Discussion (NIST Supplemental Guidance)

For each of the entities covered in IA-2, IA-3, IA-8 , and IA-9 , it is important to maintain the attributes for each authenticated entity on an ongoing basis in a central (protected) store.

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(9) 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. protected central storage used to maintain the attributes for each uniquely identified individual, device, or service is defined;
  2. the attributes for each uniquely identified individual, device, or service are maintained in <IA-04(09)_ODP protected central storage>.

Examine

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

Interview

Test

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

STIGs & CCIs

No STIG checks or CCI mappings are currently loaded for IA-4(9). 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.
