Discussion

If option "freq" is not set to a value that requires audit records to be written to disk after a threshold number is reached, audit records may be lost.

Check Content

Verify RHEL 10 is configured to flush audit records to disk after every 100 records with the following command:

$ sudo grep freq /etc/audit/auditd.conf
freq = 100

If "freq" is not set to a value of "100" or greater, the value is missing, or the line is commented out, this is a finding.

Fix Text

Configure RHEL 10 to flush audit records to disk by adding or updating the following rule in "/etc/audit/rules.d/audit.rules":

freq = 100

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

$ sudo service auditd restart
