Fix Recommendation

Configure Ubuntu 22.04 LTS to generate audit records for all modifications that affect "/etc/sudoers.d" directory.

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

-w /etc/sudoers.d -p wa -k privilege_modification

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. he <keyname> does not need to match the example above.

Check Contents

Verify Ubuntu 22.04 LTS generates audit records for all modifications that affect "/etc/sudoers.d" directory by using the following command:

$ sudo auditctl -l | grep sudoers.d
-w /etc/sudoers.d -p wa -k privilege_modification

If the command does not return a line that matches the example 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.
