Re: Setting up secure windows xp network

Windows XP comes with a half decent built in firewall. Go into your network card properties, click on the advanced tab and check the box marked "protect my computer and network my limiting or preventing access to this computer from the internet" By default this blocks *all* connections to the IP that the network card has assigned to it, so you may want to play around with the settings of the firewall, if you don't want anyone to even know your gateway machine is alive on the internet just leave it as the default since it doesn't even reply to a ping.

As a very simple method, you can try just blocking ports on the network card level in its TCP/IP properties. This is very simple and also not necessarily
the most secure.

You should be able to get some success with third party apps such as
Nortons, Mcafee and Zone Alarm. Its just a matter of configuring them
properly to suit your setup.

Hello list.
I'm in the process of securing Windows xp prof network, consisting of 5
computers.
We use "workgroup" configuration.
Also the computers are conected to internet through windows 2000 gateway computer with 2 network cards, where one card connects to ADSL router. NAT
software is in place on the gateway.
I'd much appreciate if somebody could point me to the internet recourses, or
give advise on how to make the most of windows own security features,
policies etc. Also what software firewall could we use on the gateway, since after trying norton and mcaffe firewals, we couldn't access the intrenet.

Thanks,
Anna
