sudo provides this functionality.  'su' allows you to become an
effective user.  To use 'su' to execute root commands, you require the
root password.  What, exactly, are you protecting against.

Better, IMO, to use sudo to invoke su, and restrict rights to do so to
specified users.

For restricted commands access, use the tool designed for this task,
