ℹ️ Check
Verify the "/etc/sudoers" file has no occurrences of "!authenticate" by running the following command:
$ sudo egrep -iR '!authenticate' /etc/sudoers /etc/sudoers.d/
If any occurrences of "!authenticate" return from the command, this is a finding.
✔️ Fix
Remove any occurrence of "!authenticate" found in "/etc/sudoers" file or files in the "/etc/sudoers.d" directory.
