1. Concerning the wireless vs. wired lan, I wouldn't expect wireless to be any safer. 2. The IIS viruses are a different breed from the email viruses. I assume I got my IIS ones from these programs that are constantly searching for web servers. During the time I was on-line getting my email or browsing, I looked like a wide-open web server. 3. A firewall doesn't have to be a big project. I'm told that there are low cost lan routers that include a firewall function. You connect the DSL modem through that function. I can testify that the software firewalls on each machine interfere with many of the programs that otherwise operate across your lan. -----Original Message----- From: accessd-bounces at databaseadvisors.com [mailto:accessd-bounces at databaseadvisors.com]On Behalf Of Jim DeMarco Sent: Friday, May 23, 2003 9:45 AM To: accessd at databaseadvisors.com Subject: RE: [AccessD] OT: DSL/IIS/Viruses What about running it on another machine on my (wireless) network that's not directly connected to my DSL modem but has Internet access via that connection? Is that any safer?

There is a MUCH safer way to do it, but it isn't super cheap. I have a custom built firewall, which I run at home. The "public" side of it connects directly to my Internet connection, in this case a 1Mbit VDSL connection. Then I have a "private" side, which connects to my LAN, and has my strict firewall rules. Only what I want gets in and out. Lastly, I have a "DMZ". This is where I place my publicly accessable machines. It is still firewalled, but not as stringently as the LAN side, since the public needs to hit it. Even in this DMZ I only let through the ports I absolutely need to. Such as 80 & 443 for Web, 25 & 110 for e-mail, etc. My LAN is also firewalled from my DMZ in this configuration except for what's absolutely needed. In this confugiration, unless I specifically open an e-mail with a virus attached, or something silly like that, I'm about as safe as one can get from "the big bad Internet". The worst that can happen is that there is an exploit for one of my publicly accessable boxes and they get compromised. My LAN is still safe. As a side note, my firewall, web server, and e-mail server are all running Linix or FreeBSD. This makes them less succeptable to all of the more common attacks that the "script kiddies" like to use. About 80% of the attacks and defacements on publicly accessable servers are done by "script kiddies". An added benifit is that IIS specific exploits have no affect other than to fill my logs, which archive and rotate off daily. Is this a bit excessive, since I don't run a business out of my home? Yeah, it is. But there's no such thing as too much security. --- John Frederick <j.frederick at att.net> wrote: > Yes, it is necessary.
