Assessment Procedure

Check Text

If the system is configured to immediately offload audit records to an external system, this requirement is not applicable.

Verify the audit system is configured to write logs to the disk using the following command:

$ sudo grep write_logs /etc/audit/auditd.conf 

write_logs = yes 
 
If "write_logs" does not have a value of "yes", the line is commented out, or the line is missing, this is a finding.

Implementation Procedure

Fix Text

Configure the audit system to write log files to the disk.

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

write_logs = yes 

Restart the audit daemon for changes to take effect.
