Rule Text

RHEL 10 must take appropriate action when the internal event queue is full.

Description

Discussion Text

The audit system must have an action set up in case the internal event queue becomes full so that no data is lost. Information stored in one location is vulnerable to accidental or incidental deletion or alteration. Off-loading is a common process in information systems with limited audit storage capacity. Satisfies: SRG-OS-000342-GPOS-00133, SRG-OS-000479-GPOS-00224

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.

if [ ! -f "/etc/audit/auditd.conf" ]; then
  echo "FAIL"
  exit 1
fi

grep -qE "^\\s*overflow_action\\s*=\\s*(syslog|single|halt)\\s*$" /etc/audit/auditd.conf
if [ $? -eq 0 ]; then
  echo "PASS"
  exit 0
fi

echo "FAIL"
exit 1

Remediation

Configure RHEL 10 to take appropriate action when the internal event queue is full.

Edit the "/etc/audit/auditd.conf" file and add or update the "overflow_action" option:

overflow_action = syslog

Restart the audit daemon with the following command for the changes to take effect:

$ sudo service auditd restart
