Verify Amazon Linux 2023 requires users to reauthenticate for privilege escalation.
Ensure that "/etc/sudoers" has no occurrences of "!authenticate" with the following command:
$ sudo grep -ir '!authenticate' /etc/sudoers /etc/sudoers.d/

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