Fix Recommendation

Configure TOSS 5 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/*

Check Contents

Verify "/etc/sudoers" has no occurrences of "!authenticate" using the following command:

$ sudo grep -ir '!authenticate' /etc/sudoers /etc/sudoers.d/*

If any occurrences of "!authenticate" are returned, this is a finding.
