CCIE Security Version 4 – The ASAs

My study of the ASAs is drawing to a close. My plan was to do a lot of posts regarding these studies, but as you might guess, it is too difficult to study and do a lot of blogging on the process when you are dealing with a fixed amount of time for actual study. Here is a recap of prep required on the ASAs.
