Ubuntu OS must have a crontab script running weekly to off-load audit events of standalone systems.

Information stored in one location is vulnerable to accidental or incidental deletion or alteration.

Off-loading is a common process in information systems with limited audit storage capacity.

Verify there is a script that off-loads audit data and the script runs weekly by using the following command:

Note: If the system is not connected to a network, this requirement is not applicable.

     $ ls /etc/cron.weekly 
     <audit_offload_script_name> 

Check if the script inside the file off-loads audit logs to external media.

If the script file does not exist or does not off-load audit logs, this is a finding.

Create a script that off-loads audit logs to external media and runs weekly.

The script must be located in the "/etc/cron.weekly" directory.
