Cable and DSL Internet Connections: Implementation and Security Issues
Steve Heffner, Pennington Systems
If you dial in for your Internet connection, your Internet address is "dynamic": you get a different one every time. However, if you have a "broadband" connection, typically either DSL or cable, your Internet address is "static": it stays the same all the time.
Theoretically, dynamic Internet addresses can be hacked, but practically speaking, it's not much of a risk. Static addresses, however, are highly vulnerable to attack. We will discuss the risks inherent in having a static Internet address, and ways in which you can reduce that risk by protecting your computer from nefarious attacks. These protections can consist of hardware, software, or a combination of both.
