RE: win2k firewall

Because when you pass ports through a packet filter
into a machine offering
services, OpenBSD isn't going to help you.  There is
little difference
between doing this and just turning off all services
other than the public
ones and putting it right on the Internet with no
protection at all.

Protection is relative...specifically, what are you
protecting?  What is the point of putting BlackICE on
a system, particularly a web server?  Turning off all
unnecessary services (on a web server, that would be
anything other than the web services...otherwise, it's
not a web server) gives you fewer things to manage,
and more CPU time and memory available for the web
server.
 
BlackIce inspects ALL traffic, to include the
traffic being allowed through
whatever firewall, and can actively block malicious
attempts while letting
through legitimate traffic.  

But wouldn't malicious attempts be "blocked" by simply
not running services that someone could attempt to
exploit?  If there's nothing to attack, there's also
nothing to manage.

P.S. Please don't refer to Steve Gibson's site in an
attempt to defame ISS's
current BlackIce product - especially the one
designed specifically for servers.

Please don't dictate what people can and cannot post. 
If you feel the need to do so, please do so directly
to the poster, rather than the list.
