How secure are Cable Modems and DSL Lines?
Cable vs. DSL: Security
Both Cable and DSL lines are open as long as your computer is turned on. That has certain security ramifications. DSL providers will assign you a fixed IP address; a cable company typically assigns you a "floating" IP address, each time you log on. The "floating" address probably gives you a bit of added security from hackers, but you'll want to get a personal firewall system, just to be on the safe side.
