Fix Recommendation

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

Add or update the following rule 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

Check Contents

Verify if the Ubuntu operating system is configured to audit the execution of the module management program "modprobe" by running 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" allows for specifying an arbitrary identifier, and the string after it does not need to match the example output above.
