Check Text (C-73390r1101823_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-73291r1049545_fix)

Configure AlmaLinux OS 9 to not allow users to execute privileged actions without authenticating.

Remove any occurrence of "!authenticate" found in the "/etc/sudoers" file or files in the "/etc/sudoers.d" directory with the following command:

$ sed -i '/\!authenticate/ s/^/# /g' /etc/sudoers /etc/sudoers.d/*
