Requirements NIST SOURCE

Prohibit the use of cached authenticators after [time period].

Discussion (NIST Supplemental Guidance)

Cached authenticators are used to authenticate to the local machine when the network is not available. If cached authentication information is out of date, the validity of the authentication information may be questionable.

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(13) 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. the time period after which the use of cached authenticators is prohibited is defined;
  2. the use of cached authenticators is prohibited after <IA-05(13)_ODP time period>.

Examine

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

Interview

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

Test

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

STIGs & CCIs

No STIG checks or CCI mappings are currently loaded for IA-5(13). 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.
