Requirements NIST SOURCE

Provide an alternate audit logging capability in the event of a failure in primary audit logging capability that implements [alternate audit logging functionality].

Discussion (NIST Supplemental Guidance)

Since an alternate audit logging capability may be a short-term protection solution employed until the failure in the primary audit logging capability is corrected, organizations may determine that the alternate audit logging capability need only provide a subset of the primary audit logging functionality that is impacted by the failure.

Engineering Interpretation

Original engineering commentary written for this explorer — not NIST source text and not authoritative guidance.

No engineering interpretation has been authored for AU-5(5) 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. an alternate audit logging functionality in the event of a failure in primary audit logging capability is defined;
  2. an alternate audit logging capability is provided in the event of a failure in primary audit logging capability that implements <AU-05(05)_ODP alternate audit logging functionality>.

STIGs & CCIs

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