Some starting points:
-read up on IPTABLES … spend a day getting familiar with setting up IPTABLES for one machine. Lock everything down except your ssh port and whatever else you are using (web, VPN, etc). After you get the basic idea you can do all of your VMs
-Use 6g htaccess https://perishablepress.com/6g/ on your websites
-If you use Wordpress, install a plugin like LoginLockdown
-harden your ssh http://bodhizazen.net/Tutorials/SSH_security#Server
