Fix Recommendation

Configure the SUSE operating system to remove any occurrence of "NOPASSWD" or "!authenticate" found in the "/etc/sudoers" file. If the system does not use passwords for authentication, the "NOPASSWD" tag may exist in the file.

Check Contents

Verify that the SUSE operating system requires reauthentication when changing authenticators, roles, or escalating privileges.

Check that "/etc/sudoers" has no occurrences of "NOPASSWD" or "!authenticate" with the following command:

> sudo egrep -i '(nopasswd|!authenticate)' /etc/sudoers

If any uncommented lines containing "!authenticate", or "NOPASSWD" are returned and active accounts on the system have valid passwords, this is a finding.
