Fix Recommendation

Configure the audit system to generate an audit event for any successful/unsuccessful use of the "sudo" command.

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

-a always,exit -F path=/usr/bin/sudo -F perm=x -F auid>=1000 -F auid!=4294967295 -k priv_cmd

To reload the rules file, issue the following command:

$ sudo augenrules --load

Check Contents

Verify that an audit event is generated for any successful/unsuccessful use of the "sudo" command.

Check the configured audit rules with the following command:

$ sudo auditctl -l | grep /usr/bin/sudo

-a always,exit -F path=/usr/bin/sudo -F perm=x -F auid>=1000 -F auid!=-1 -k priv_cmd

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" allows for specifying an arbitrary identifier, and the string after it does not need to match the example output above.
