Check Text ( C-52015r860913_chk )
Verify that "/etc/sudoers" has no occurrences of "NOPASSWD".

Check that the "/etc/sudoers" file has no occurrences of "NOPASSWD" by running the following command:

$ sudo grep -ir nopasswd /etc/sudoers /etc/sudoers.d

%admin ALL=(ALL) NOPASSWD: ALL

If any occurrences of "NOPASSWD" are returned from the command and have not been documented with the ISSO as an organizationally defined administrative group using MFA, this is a finding.
