Assessment Title

Rule Text

The audit system must identify staff members to receive notifications of audit log storage volume capacity issues.

Description

Discussion Text

Email sent to the root account is typically aliased to the administrators of the system, who can take appropriate action.

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

Checks

OVAL

oval:mil.disa.fso.redhat.rhel6:var:2122 ← xccdf_mil.disa.stig_value_var_auditd_action_mail_acct

DISA STIG (Manual Reference)

Inspect "/etc/audit/auditd.conf" and locate the following line to determine if the system is configured to send email to an account when it needs to notify an administrator: 

action_mail_acct = root


If auditd is not configured to send emails per identified actions, 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.

test_1() {
  (sed -En 's/^action_mail_acct\s*=\s*(\S+)\s*$/\1/p' '/etc/audit/auditd.conf') | grep -qxF 'root'

  echo "PASS"

Assessment Script Powered by AISandbox-executed

A standalone Shell script to assess this control automatically. Review before running it in your environment.

Syntax-checked and actually executed in an isolated sandbox (not the real system this checks) — confirmed to run without errors.

#!/bin/sh
# DISA STIG / SCAP compliance check for oval:mil.disa.fso.redhat.rhel6:def:548
if grep -q "^action_mail_acct\\s*=\\s*root$" /etc/audit/auditd.conf; then echo "PASS"; else echo "FAIL"; fi
exit 0

Remediation

The "auditd" service can be configured to send email to a designated account in certain situations. Add or correct the following line in "/etc/audit/auditd.conf" to ensure that administrators are notified via email for those situations: 

action_mail_acct = root
