Road Runner Security - File and Print Sharing2001-02-01 (updated: 2003-02-01) by Kelly Pruett
You run a great site and I have very much enjoyed your tips. I'd like to share a story about security on the Roadrunner cable modem service that happened to me.
About three weeks after starting my Roadrunner account I went to my home computer to check my email. I found a nice little folder on my desktop indicating that my computer was completely unsecure. What scared me is that the hacker took copies took copies of a few files on my PC (registry, etc) and edited them, placing them in this directory. Had he actually put these files in place, I would have never run the PC again without a reload. In short, they were polite enough to let me know I had a problem, but scary enough to taunt me with what they could have done.
Now the bad part is that I work in a networking field. I know better than to do what I did, which was have my PC shared out to the rest of the PC's on my own home LAN. However, I SPECIFICALLY asked the question to my Roadrunner installer, and he assured me that the connection was encrypted, secure ... blah blah, etc. Fixing the problem was easy, I just unshared my PC in Windows networking. But had I not heard the statements from the installer, I would have done this anyway. I have since been able to fix things to do "as I want" again on my home LAN.
I saw several recommendations for software from your site, all good. I would add one more to that. Winroute by Tiny Software. It includes the ability to do NAT, routing, and firewalling, in addition to several other features your users might like, including a small email server (relay) and DHCP server. In fact, for anyone wanting to do PAT (port address translation), I would highly recommend this over some of the other products.
Again, thanks for the great site, and keep up the great tips for broadband users.
