Check

Verify that the "/etc/sudoers" file has no occurrences of "!authenticate" by running the following command:

$ sudo grep -Ei !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 the "/etc/sudoers" file or files in the "/etc/sudoers.d" directory.
