Ok, what are you thoughts on Ken's changes? If we leave the question as
is, then I think we have to say that there is always a chance of the
zone being modified by an attack or malware. I'd much rather have the
question be about additional protections than all the risks.

So I made a bunch of additions to 4.2 to hopefully provide better clarity through the question.  See if it helps?
