| Verify the "/etc/sudoers" file has no occurrences of "NOPASSWD" or "!authenticate" by running the following command: $ sudo egrep -i '(nopasswd|!authenticate)' /etc/sudoers /etc/sudoers.d/* If any occurrences of "NOPASSWD" or "!authenticate" return from the command, this is a finding. |
| ✔️ Fix |
