Re: Internal Servers (noob post)

While I am not a Pen tester I have, like you, read a lot about it and took
some classes on the subject.  One thing that a prof of mine always made sure
we understood is the possibility of an internal attack.  It isn't always
going to be the hacker on the outside going in, sometimes they are already
inside.  If you don't plan for that then you will be in deep water if it
ever happens.
