Is Obsolescence Good Computer Security?

caesar-auf-nihil asks: "I was recently considering a switch from dial-up to something faster (either cable or DSL) but my friend recommended against it since he said I was more secure staying with Dial-Up. His argument was that my connection's slowness and 'not always on' connection gave me better security since I was less of a target for many security threats. Now, I have never gotten infected, nor do I believe my machine is infested with spyware and/or controlling programs as it runs fine, but I wonder if the obsolescence argument is really good or not. Does Dial-Up really protect you or is this a false sense of security and I should just go ahead and pick a faster service and make sure my firewall is a good one and my virus definitions are always up to date?"

      You really have to think about the vectors of infection. With dial up you're less likely to be infected by a probe of your computer that's scanning for a vulnerability since, as you said, it's not an always-on connection.

      But is that really how you get virii & spyware? I think not. The same access points are still there. A website that installs spyware thu activex doesn't care that you're on dial up. The trojan in the warez you (patiently) downloaded doesn't care either. Accessing the Internet puts you at risk. Thinking that a slow connection is the sole determinant of your value is naieve.

I think Netgear has a few for small/medium businesses, but if all you want is a NAT box, Linux/*BSD work quite well on some pretty low-end hardware. 100 users on a DSL/Cable circuit could be handled by an old Pentium 133 picked up on eBay for $25.

It's not a daunting task to configure a setup that will secure your home computer to a suitable degree. Just your ordinary broadband router should include a firewall that should be sufficient, and the Windows firewall is also likely sufficient.

    If you aren't an expert on setting up your network, then just find one of your more tech-savvy friends (not the one that told you to stay on dialup!) and have them check your router/firewall configuration. There are also websites you can visit (Symantec?) that will perform a check on various ports for basic vulnerabilities.
