I recommend closing as much ports as possible.
E.g.: If you need to ssh to the machine, allow port 22 only from  
known, trusted IPs and subnets.

There are so many things you have to pay attention to, like patch  
management etc. that it would be best to use the NSA hardening guide  
or things like that.
