In essence the features of a separate box are about the same as what the software solutions provide. This is described in the article about " Software NAT, Firewall or Proxy?

Extractions: Table of contents Cable Modems are different, but the basic architecture is more or less the same as shown above. The major components are outlined below, along with an indication of some companies that are know to deliver products to the open market. Many other companies are working in the field, but may not be so well known to me - or may only produce components for their own use. The tuner connects directly to the CATV outlet. Normally a tuner with build-in diplexer is used, to provide both upstream and downstream signals through the same tuner. The tuner must be of sufficiently good quality to be able to receive the digitally modulated QAM signals. Companies like ALPS, Sharp, Temic and Panasonic are strong suppliers here. A new concept of a silicon tuner is in the works. This is basically a tuner on a chip, and is expected to cut the cost down quite a bit compared to a more conventional tuner module. In the receive direction, the IF signal feeds a demodulator. The demodulator normally consists of A/D converter, QAM-64/256 demodulator, MPEG frame synchronization, Reed Solomon error correction.

SecurityFocus HOME News: Cable Modem Hackers Conquer The Co-ax To make Sigma work, uncappers most commonly use a hardware hack developed by DOCSIS (Data Over cable Service Interface Specification), cable modems only permit http://www.securityfocus.com/news/7977
Extractions: Cable modem hackers conquer the co-ax By Kevin Poulsen SecurityFocus Feb 5 2004 5:00AM A small and diverse band of hobbyists steeped in the obscure languages of embedded systems has released its own custom firmware for a popular brand of cable modem, along with a technique for loading it a development that's already made life easier for uncappers and service squatters, and threatens to topple long-held assumptions about the privacy of cable modem communications. The program, called Sigma, was released in its final version last month, and has reportedly been downloaded 350 to 400 times a day ever since. It's designed to be flashed into the non-volatile memory of certain models of Motorola's Surfboard line, where it runs in parallel with the device's normal functionality. It gives users almost complete control of their cable modem a privilege previously reserved for the service provider. The project is the work of a gang of coders called TCNiSO . With about ten active members worldwide, the group is supported by contributions from the uncapping community speed-hungry Internet users who rely on TCNiSO's research and free hackware to surmount the bandwidth caps imposed by service providers, usually in violation of their service agreement, if not the law. To them, Sigma is a delight, because it makes it simple to change the modem's configuration file the key to uncapping, and, on some systems, to getting free anonymous service using "unregistered" modems. "I've known TCNiSO for two years now and I've done a lot of things with their techniques," wrote a Canadian uncapper in an e-mail interview. "Sigma is the greatest one I've seen."

Extractions: Tell us your opinion Cable access is a great value fast connection for tele-workers and small offices. But how do you deal with the security risks? Broadband connectivity has become the most sought after service for home and business computers. Getting 512 kilobit/s (kbps) or a Megabit for a small monthly fee is just too good to pass up. Many organisations are opting to install cable modem connections; according to the March 2002 issue of Cable Datacom News, more than 10 percent of the U.S. online community is connected via broadband. While the UK is behind this figure, penetration is growing here too. According to some precise definitions, cable modems are broadband connections, while DSL should more precisely be called a "baseband" connection, since it is not shared. However, in practice broadband simply means "fast" and is applied to both types of connection. This article will focus on the risks of cable, some of which also apply to DSL. Broadband offers many benefits, but the widespread use of broadband access is not all good news. Cable is insecure, and most organisations are completely unaware of these risks. However, there are some solutions and countermeasures for combating threats and protecting your data and your network.
Cable Modems -- Not Just A Security Problem - ZDNet UK Insight Tuesday 25th May 2004. cable modems not just a security problem. It s no mystery why cable modems are saturating the corporate communications environment. http://insight.zdnet.co.uk/hardware/servers/0,39020445,2119152,00.htm
Extractions: Tell us your opinion As well as securing home-office cable connections, IT managers will have to deal with increased loads on corporate networks, and demands to support users at home It's no mystery why cable modems are saturating the corporate communications environment. They're fast, readily available, increasingly reliable, and relatively easy to install. Yet the security of the shared infrastructure on which cable modems operate has long been a key point of debate between modem advocates and skeptics. In general, tech leaders don't relish the idea that vital corporate information is, at least theoretically, available to the hacker next door. The devices represent a big change for enterprises, however, and there are several issues CIOs must be aware of. Cable modems have long raised security concerns related to how addresses are distributed within the networks' shared infrastructure. In addition, the sudden spike in the volume and type of applications demanded by off-site workers can and will stress enterprise resources. Security issues CIOs are well advised to assume that cable modem access is inherently insecure . In addition to physically sharing infrastructure with other modems, the devices usually have a fixed IP address which is vulnerable to attack. Although this does not expose the corporate network directly, it can give an attacker access to anything on the system at the user's home. Clearly, this means that extra security precautions are necessary. Traver believes that a combination of IP VPNs, software firewalls, and/or next-generation connectivity products from companies such as Neoteris or Flatrock are vital to protecting remote desktops.
