Discussion

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.

Check Content

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

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.
