Tom Liston explains the ZA hole to Michelle.

Subject: A paragraph or two clearly explaining...


What's going on:

Normal communications:  Each endpoint opens what are known as
'sockets' in order to communicate.  To communicate using a
socket, essentially you just dump your data in, and listen to what
comes out.  The socket takes care of the low level networking
'stuff'.

What we're doing:  We're taking care of all of the low level
networking 'stuff' ourselves.  We create our own packets, right
down to the 'link layer', and dump them straight out onto the wire
with no socket involved.

The problem:  ZA (and I would be willing to bet ALL 'personal
firewalls') watch for/trap/stop data at the socket level.
