My situation is this:

I have a small business with 5 users. Each user can access our clients data
from our internal file server. All users are running XP Professional, as is
the server machine.

All of us require daily internet access, which is broadband cable behind a
router. Each system is running a Security Suite with personal firewall.
What I need to do is be as certain as is "practically" possible that our
clients data is not "compromised" from the outside ( via our broadband
connection ).

What - if anything - should I add to this setup to be more secure from
"outside" hacking?

All comments are certainly appreciated

Go to http://www.grc.com and run the ShieldsUp test.

The main concerns here are ports 137-139 and 445, which are the file-sharing
ports.

Also stop using Internet Explorer. Get a more secure browser, as IE is the
route most Trojans get  onto computers by.
