Requirements NIST SOURCE

Require users to re-authenticate when [circumstances or situations].

Discussion (NIST Supplemental Guidance)

In addition to the re-authentication requirements associated with device locks, organizations may require re-authentication of individuals in certain situations, including when roles, authenticators or credentials change, when security categories of systems change, when the execution of privileged functions occurs, after a fixed time period, or periodically.

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-11 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. circumstances or situations requiring re-authentication are defined;
  2. users are required to re-authenticate when <IA-11_ODP circumstances or situations>.

Examine

[SELECT FROM: Identification and authentication policy; procedures addressing user and device re-authentication; system security plan; system design documentation; system configuration settings and associated documentation; list of circumstances or situations requiring re-authentication; system audit records; 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-11. 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.
