The difference is only in how much the hosting system forces you to use certain images and versions, which will likely vary with the vendor. Books on security are always out of date anyway. The system security business is very specialized - plan on spending a lot of either time or money if you are going to do anything out of the ordinary. But, unless you have something unique and valuable to attack, you mostly have to worry about known exploits on the platform you use, and the main thing you can do about it is to keep your software updated so you get the fixes as soon as they are available. -- Les Mikesell lesmikesell at gmail.com
