Requirements NIST SOURCE

Authorize read-only access to audit information to [subset of privileged users or roles].

Discussion (NIST Supplemental Guidance)

Restricting privileged user or role authorizations to read-only helps to limit the potential damage to organizations that could be initiated by such users or roles, such as deleting audit records to cover up malicious activity.

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-9(6) 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. a subset of privileged users or roles with authorized read-only access to audit information is defined;
  2. read-only access to audit information is authorized to <AU-09(06)_ODP subset of privileged users or roles>.

Examine

[SELECT FROM: Audit and accountability policy; system security plan; privacy plan; access control policy and procedures; procedures addressing protection of audit information; system design documentation; system configuration settings and associated documentation; system-generated list of privileged users with read-only access to audit information; access authorizations; access control list; system audit records; other relevant documents or records].

Interview

[SELECT FROM: Organizational personnel with audit and accountability responsibilities; organizational personnel with information security and privacy responsibilities; system/network administrators].

Test

[SELECT FROM: Mechanisms managing access to audit information].

STIGs & CCIs

No STIG checks or CCI mappings are currently loaded for AU-9(6). 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.
