That has to be done at kernel level.
There are kernel security enhancements like SELinux where you can
restrict even root's privileges and this way make it impossible for an
attacker to install anything. Of course this means that you have to
reboot anytime before and after updating or installing software.
There are other tools like samhain that try to detect at least if
someone is intruding you system.
