Assessment Title

Rule Text

The audit system must alert the System Administrator (SA) if there is any type of audit failure.

Description

Discussion Text

Proper alerts to system administrators and Information Assurance (IA) officials of audit failures ensure a timely response to critical system issues.

How this relates to the STIG checklist: STIG vs SCAP benchmark.

Checks

DISA STIG (Manual Reference)

This check applies to the global zone only. Determine the zone that you are currently securing.

# zonename

If the command output is "global", this check applies.

The root role is required.

Verify the presence of an audit_warn entry in /etc/mail/aliases.
# /usr/lib/sendmail -bv audit_warn
If the response is:
audit_warn... User unknown

this is a finding.

Review the output of the command and verify that the audit_warn alias notifies the appropriate users in this form:

audit_warn:user1,user2

If an appropriate user is not listed, this is a finding.

SCC Automation Reference

The reconstructed evaluation script behind this rule's OVAL check(s) — every module a compound check combines, with this rule's own concrete values and DISA's SCC tool's real per-module mechanism curated from static teardown of SCC releases.

Remediation

The root role is required. 

This action applies to the global zone only. Determine the zone that you are currently securing.

# zonename

If the command output is "global", this action applies.

Add an audit_warn alias to /etc/mail/aliases that will forward to designated system administrator(s).

# pfedit /etc/mail/aliases

Insert a line in the form:
audit_warn:user1,user2

Put the updated aliases file into service.
# newaliases
