A major problem is the TCP/IP, and it's standards.  That is how the bad 
guys get in.  But, to be on the internet, TCP/IP is what one must speak. 
  You can protect it every way you can think of, but, there will be some 
way you didn't think of, and the bad guys have discovered.

One thing that should work to some extent, is to have a private 
communications protocol, and don't run TCP/IP on internal systems.  That 
probably won't work on many systems, since the capability of designing 
and implementing such is beyond most shops.

Like it or not, security by obscurity is the only thing that will work. 
If the bad guys don't know how to talk to your system, and you don't 
have any known comm protocol, they will have a much harder time.
