Another trick that can be used is port knocking.  Pretty neat idea. 
Send a series of connection attempts on different ports.  Software on
the server monitors the log files and when it sees the correct sequence
it opens up the port your application connects on.  Kind of a
combination lock for your server.

fwknop is one implementation of this.
