This is a three part guide to DSL/Cable security, starting with Part 1, which identifies the problem, continuing with Part 2 where we delve into the topic of vulnerability testing to find out just how susceptible your systems are to attack, followed by Part 3 where we discuss a variety of hardware and software solutions to keep your systems secure. -Ed.
Those embarking on the broadband Internet journey should be aware of the associated security pitfalls. While DSL and cable modems offer a quantum leap in performance, they also open the door for more hacker attacks.
Contrary to popular opinion, security should be on the minds of DSL users as much as those who use cable modems. The conventional wisdom is that DSL is a more secure service because it provides a dedicated connection to the Internet, while cable is less secure because it provides a shared connection. That is, DSL users are connected directly to a telco central office, while cable users share a pool of bandwidth that originates at a neighborhood hub. As a result, the media has focused on the dangers of shared cable modem networks. Because cable providers effectively implement neighborhood LANs, there exists a very real fear that neighbors can spy on other neighbors.
We'll examine the ramifications of that issue later in this guide. But beyond that difference in local networking architecture, there are many more security risks posed by both DSL and cable services. A close look at the fine print of many broadband service agreements reveals an acknowledgement of the security risks. Read those agreements before you acquire broadband service.
Let's look at some of the security factors you should keep in mind when using your broadband connection.
