Assessment Title

Rule Text

The Red Hat Enterprise Linux operating system must immediately notify the System Administrator (SA) and Information System Security Officer (ISSO) (at a minimum) when the threshold for the repository maximum audit record storage capacity is reached.

Description

Discussion Text

If security personnel are not notified immediately when the threshold for the repository maximum audit record storage capacity is reached, they are unable to expand the audit record storage capacity before records are lost.

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

DISA STIG (Manual Reference)

Verify the operating system immediately notifies the SA and ISSO (at a minimum) via email when the threshold for the repository maximum audit record storage capacity is reached.

Check what account the operating system emails when the threshold for the repository maximum audit record storage capacity is reached with the following command:

# grep -i action_mail_acct  /etc/audit/auditd.conf
action_mail_acct = root

If the value of the "action_mail_acct" keyword is not set to "root" and other accounts for security personnel, this is a finding.

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.

if [ ! -f "/etc/audit/auditd.conf" ]; then echo "PASS"; exit 0; fi
if grep -q "^[ ]*action_mail_acct[ ]+=[ ]+root[ ]*$" /etc/audit/auditd.conf; then echo "PASS"; exit 0; else echo "FAIL"; exit 1; fi

Remediation

Configure the operating system to immediately notify the SA and ISSO (at a minimum) when the threshold for the repository maximum audit record storage capacity is reached.

Uncomment or edit the "action_mail_acct" keyword in "/etc/audit/auditd.conf" and set it to root and any other accounts associated with security personnel. 
 
action_mail_acct = root
