I used to install cable modems for Time Warner with there Road Runner
service. When you are connected to a cable modem it is no different
then being on a LAN. You are running TCP/IP. There are some good
personal firewall programs out than can allow you to add the extra layer
of security to your system. Having NTFS as the file system with a secure
ACL will also help. but the one thing to remember is it is just a Large
network. no different from your average corporations net.
