Well articulated James, I have a client who has been running sbs 2000
with isa installed and has never in all these years had a security
breach tho' many have tried.
There is no problem with a loaded sbs server, 2000 or 2003...as long as
it's done right.

Unscrew the top of your head and let some light in.
It's exactly this sort of self-serving, elitist rhetoric that causes
folks to feel like they "just can't do it".
There isn't and never will be "just one right way" to do something.
There are external factors that are not always controllable.
Security is and will always be a balancing act between requirements,
money and hardware resources.
"Fast, Secure or cheap; choose two" is one of my favorite quotes.

Which is why you'll never see anyone in their right mind running SBS who
expects the same level of protection from a dedicated system.
I forwarded that e-mail from Tom to the guys at work, and the first
thing they did is say: Look at ISA! It's a piece of junk since you've
gotta do a work around just to make stuff even work on the box! You
never have that problem with a PIX!
If you're boss won't look at the cost justification of buying a low end
desktop to run a service, all I have to say to any financial institution
is how much is the cost of an FDIC audit in terms of your labor?
Pulling 50% of the IT staff into meetings with the FBI/FDIC/Secret
Service (yes, the secret service is involved in these types of audits)
for 2 months along with hiring a small army of people to produce all
your audit trails for the past
7 years is by FAR more expensive than any server that I can think of....
What I was getting at in my first e-mail is that since you can't even
install services on a PIX, you'd need to purchase or use another server
anyways, which is why you should leave things off of an ISA box and just
not even open yourself up to an service exploit.....

"Hardware"; thpthpthpthpthp
Please drop this blatant BS; until it's implemented in the ASICs, it
ain't "hardware".
Facts:
- Installing service on any machine is only as functional or secure
as the person deploying / securing it.
- There are folks with more motivation than $$
- These same folks need an answer, not attitude.
- placing services on the firewall is not for the faint of heart;
this is why the SBS folks spend years perfecting the compromise.

Installing services on your ISA box is like hiring a blind, deaf body
guard
and expecting him to walk you to the other side of the street..... Only
bad
things can happen.....
Suggestion: The service you've installed can't be mission critical,
otherwise you'd have a dedicated server..... BYOS (build your own
@#(*$&)@(#*ing server) or put it on a cheap POJ (Piece of Junk) box....
Besides, I'd love to see someone try and install a service on a PIX box
anyways...... so the hardware firewall people can't even bring this up
as a
'flaw'...... even though i am a fan of hardware at the entrance for bulk
processing of incoming/outgoing traffic......

They left out the most obvious solution, and the one which is usually
the
most correct... Move the service to something besides your firewall.

Very interesting KB article and an issue that I'm sure will generate a
lot
of heat in the coming months.
