Fix Recommendation

Configure Ubuntu OS to audit the execution of the module management program "modprobe".

Add or modify the following line in the "/etc/audit/rules.d/stig.rules" file:

-w /sbin/modprobe -p x -k modules

To reload the rules file, issue the following command:

$ sudo augenrules --load

Note: The "-k <keyname>" at the end of the line gives the rule a unique meaning to help during an audit investigation. The <keyname> does not need to match the example above.

Check Contents

Verify Ubuntu OS is configured to audit the execution of the module management program "modprobe" with the following command:

$ sudo auditctl -l | grep /sbin/modprobe
-w /sbin/modprobe -p x -k modules

If the command does not return a line, or the line is commented out, this is a finding.

Note: The "-k" value is arbitrary and can be different from the example output above.
