Security By Kevin Poulsen, SecurityFocus Published Thursday 5th February 2004 22:33Â GMT 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.

Extractions: In their drive to market broadband cable to everyone, a key challenge for the major cable system operators was to get together and develop a standard method of implementing high-speed data services across the industry. Such a method would encourage many manufacturers to develop standard subscriber and head-end products; the cost benefits of high-volume production would accrue to both the multiple system operators (MSOs) and subscribers. Moreover, standard subscriber products could lead to a consumer retail business model for cable modems similar to that of traditional dial-up modems. So the cable industry created its own technical specification called the Data over Cable Service Interface Specification, or Docsis. Cable Laboratories Television Inc. (known as CableLabs), a research and development group for the industry, administers the standard and ensures interoperability among vendors and equipment types. These first-generation implementations have delivered great value to the industry by validating the specification, the technology and the marketplace. However, as residential applications and usage continue to increase and as consumer lifestyles become more dependent upon high-speed links to the home, the demand for highly reliable service and higher performance will continue to increase. MSOs increasingly require high-reliability and high-availability infrastructure, including new-generation cable modem termination systems (CMTS).
Intel Driving Low-cost Cable Modems | CNET News.com Intel driving lowcost cable modems The chipmaker is collaborating with other less expensive and easier to upgrade than traditional hardware modems. http://www.news.com/News/Item/0,4,32406,00.html
Extractions: TrackBack Print E-mail TalkBack High-speed cable modems may become cheaper in the near future as a result of an Intel initiative now coming to light. Intel is working with Libit Signal Processing and possibly other partners to produce a futuristic breed of devices called "host-based" cable modems. The devices would use the computer's main microprocessor and memory for some functions, rather than requiring the separate processor, memory, and operating system normally needed by a stand-alone modem. Because fewer chips are needed, they are potentially less expensive and easier to upgrade than traditional hardware modems. The effort comes at a propitious time for the cable movement: After a long and arduous process, cable modems based on industry-approved standards should be available by the end of the quarter. As a result, the long hoped-for move to sell cable modems in a retail market may finally start to develop in 1999. Cable companies are moving to provide high-speed Internet access with lower service and equipment costs. As such, compatible products based on the DOCSIS (Data Over Cable Service Interface Specifications)

Facing The Security Risks Of Cable Modems - ZDNet UK Insight Insight hardware. Thursday 4th August 2005 According to some precise definitions, cable modems are broadband connections, while DSL should more http://insight.zdnet.co.uk/hardware/servers/0,39020445,2118716,00.htm
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 Insight hardware. Saturday 13th August 2005 Yet the security of the shared infrastructure on which cable modems operate has long been a key point of 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.

Extractions: There are two requirements for establishing a dial-up connection to a telecommunications network such as FIRN. First, you must have the necessary hardware (a computer with a modem) connected properly. Second, you must have the appropriate software (computer programs) installed on your computer. Hardware for telecommunications Almost any type of computer can used for telecommunications. A high-end computer is strongly recommended if you are planning to connect to the World Wide Web. One advantage of exchanging information through telecommunications is that different types of computers can communicate directly with each other. In other words, a Macintosh computer can send information to a Windows computer just as easily as it can to another Macintosh computer. Phone Line Another issue to consider is that some of the newer telephone systems are not compatible with standard modems. A school or business telephone that has a variety of features, such as call-waiting, voice mail, and call-parking, may not be compatible with a modem. Modem Data transmitted through telecommunications usually incorporates standard telephone lines as the primary carrier for the analog sound waves. One of the impediments in this process is that information on computers is stored in digital form (bits and bytes). In order to

Cable Modems And Securing The SOHO An edited version of this paper with the title Securing cable modems originally If you have a small LAN and just want protection, go with the hardware http://www.garykessler.net/library/cm_security.html
Extractions: April 2000 As recently as a few years ago, high-speed Internet access for the small office/home office (SOHO) was still an expensive proposition. The relatively recent emergence of low-cost alternatives such as cable modems and the variety of digital subscriber line (xDSL) technologies, however, has totally changed the calculus, making telecommuting and remote office connections over the Internet a breeze. FIGURE 1. Cable modem connection scenarios. The upper topology is most common; a coaxial cable delivers the service to a cable modem which in turn is connected to a computer via a 10BASE-T cable. The lower topology shows the cable modem connected to a hub/router that acts as the connection point for the SOHO LAN. Figure 1 shows the most common network connection topologies when using cable modems. The cable TV company runs a coaxial cable into the building to deliver their Internet service. Although fed from the same coax that provides cable TV service, most companies place a splitter outside of the building and runs two cables in, rather than using a splitter at the set-top box. The coax terminates at the cable modem. The cable modem itself attaches to the SOHO computing equipment via its 10BASE-T port. In most circumstances, the cable modem attaches directly to a user's computer. If a LAN is present on the premises (something many cable companies frown upon), some sort of router can be connected to the cable modem.

Cable Modem Troubleshooting Tips: USB Issues Technical tips for troubleshooting a cable modem connection. Some PCs have USB hardware that is not good enough for the high demands of a cable modem http://homepage.ntlworld.com/robin.d.h.walker/cmtips/usb.html
Extractions: NTL/BY Tech Support Some cable modems have both an ethernet socket and a USB socket. Examples include: Articles on this page: USB networking imposes a heavier load on the system processor than ethernet does, so there might be a performance impact in using USB for networking: this is unlikely to affect your network speeds, but might affect the percentage of processor time available to applications. The USB experience is influenced greatly by the quality of the USB device drivers: ethernet drivers are more mature than USB ones. Some PCs have USB hardware that needs driver updates, see below. Some PCs have USB hardware that is not good enough for the high demands of a cable modem: you might get less trouble from an ethernet card. But an ethernet card involves extra expense, whereas USB connections are built in to most modern PCs. USB cable modem drivers do not work with Windows 95, even 95 with USB Additions. If your PC already has an ethernet card, there is no contest: use ethernet.

Extractions: I'm looking for the fastest cable modem I can get. I can't find a gigabit modem, so I assume it's not available. Right now, I have a Marvell Yukon Gigabit Ethernet Controller, getting a D-Link Broadband Gigabit Gaming Router, and am stuck with a Motorola Cable Modem (SB5100) that maxes at 38mbps (supposedly). My ISP is Cox Cable and it maxes (for me) at 5mbps, but I've seen speed reports on here of up to 8mbps. to forum Print The SB5100 is DOCSIS 2.0 compliant. With Cox upgrading their systems to DOCSIS 2.0 your SB5100 is right in there and fully capable to delivering the max bandwidth that Cox is going to provide. I believe in your area the highest bandwidth (Cox Premium) is 9.0 mbps, at least that is what the last upgrade was to in the Phoenix area.
