[SC-L] [WEB SECURITY] Some unanswered website vulnerability questions

[Dinis Cruz]

Jeremiah's was inspired and wrote 5 spot-on web application security
questions (see below) which we all as a community should:a) comment &
discuss
b) research properly its implications, and
c) come up (for each question) with a set of 'this is the current situation'
 answers.

I suspect that c) will be a very uncomfortable reading for a lot of people,
but that might actually make some things change (for the better I hope)
