Check Text (C-282430r1200270_chk)
Verify the audit system is configured to flush to disk after every 100 records using the following command:
$ sudo grep freq /etc/audit/auditd.conf
freq = 100
If "freq" isn't set to a value between "1" and "100", the value is missing, or the line is commented out, this is a finding.
Fix Text (F-86896r1200269_fix)
Configure TOSS 5 to flush audit to disk by adding or updating the following rule in "/etc/audit/auditd.conf":
freq = 100
Restart the audit daemon for the changes to take effect.
