I am about to complete a LAMP installation on my Ubuntu Feisty Desktop Box. I want the GUI which is why I am using the Desktop version instead of the Server version. I know that using the server edition not only can pre-install LAMP but it also takes a lot of security steps (i.e. closing certain ports). This tutorial only installs LAMP and does not cover any additional steps that might be needed for security. Is there anything you can suggest that I do?
