Description
If option "freq" is not set to a value that requires audit records being written to disk after a threshold number is reached, then audit records may be lost.
ℹ️ Check
Verify that OL 9 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" isn't set to a value of "100" or greater, the value is missing, or the line is commented out, this is a finding.
✔️ Fix
Configure OL 9 to flush audit to disk by adding or updating the following configuration in "/etc/audit/auditd.conf":
freq = 100
The audit daemon must be restarted for the changes to take effect.
Restart auditd:
$ sudo service auditd restart
