Check Text (C-258086r1102063_chk)
Verify that "/etc/sudoers" has no occurrences of "!authenticate" with the following command:
$ sudo egrep -iR '!authenticate' /etc/sudoers /etc/sudoers.d/
If any occurrences of "!authenticate" are returned, this is a finding.
Fix Text (F-61751r926244_fix)
Configure RHEL 9 to not allow users to execute privileged actions without authenticating.
Remove any occurrence of "!authenticate" found in "/etc/sudoers" file or files in the "/etc/sudoers.d" directory.
$ sudo sed -i '/\!authenticate/ s/^/# /g' /etc/sudoers /etc/sudoers.d/*
