Check Text (C-282735r1201185_chk)

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.

Fix Text (F-87201r1201184_fix)

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/*
