Ensure only owner and members of group owner of /usr/bin/sudo can execute it
An XCCDF Rule
Description
Remove the execute permission bit of /etc/bin/sudo for the other users.
To properly set the permissions of /usr/bin/sudo, run the command:
$ sudo chmod 4110 /usr/bin/sudo
Rationale
Restricting the set of users able to execute commands as privileged user reduces the attack surface.
