• Hi Ali, this is actually several different questions. Some of them have already been answered, you can search through the [hardening] tag. Please split them out to individual questions, and add some more detail on your context, risk profile, etc - See the FAQ and How to Ask. – AviD Mar 21 '12 at 7:49
