Check Text (C-275647r1147991_chk)
Verify the "/etc/sudoers" file has no occurrences of "NOPASSWD" or "!authenticate" by using the following command:
$ sudo grep -Ei '(nopasswd|!authenticate)' /etc/sudoers /etc/sudoers.d/*
If any occurrences of "NOPASSWD" or "!authenticate" return from the command, this is a finding.
Fix Text (F-79654r1147990_fix)
Remove any occurrence of "NOPASSWD" or "!authenticate" found in "/etc/sudoers" file or files in the "/etc/sudoers.d" directory.
