on further invesitgation, Thirdly, and most importantly, DOCSIS provides a feature called Baseline Privacy. This is a very secure encryption method that protects data while it resides on the RF plant. That means that even if someone figures out a way to get all of your downstream traffic from the RF carrier, which is unlikely, if Baseline Privacy is enabled they still have to decrypt it. A case could be made that the RF portion of a Baseline Privacy enabled cable plant is the most secure portion of the net. Remember, however, that Baseline Privacy only protects your signal while on the RF plant. All normal precautions for sending data out on the Internet still need to be obeyed
http://www.docsis.org/faq.php3 >>> "Patrick Ramsey" 03/18/02 03:32PM >>> depending on the carrier, docsis could be implemented...I have not tcpdumped my current connection (through att) but I believe att does filter. a quick search on google yielded some docsis info but I didn't see whether or not it was done at the modem or the switch. I'm guessing the latter. I would hate to think I could go out and by any modem I wanted to and change the way att does business... :) -Patrick >>> "sam sneed" 03/18/02 02:56PM >>> I just changed services from DSL to cable modem. I have heard from people, including verizon, that cable is not as secure as DSL becuase it is over a shared medium. I connected to my cable modem and fired up my packet sniffer. I did not see anyone elses traffic on the line so i am assuming the bandwith is shared( a known fact about cable access) but is somehow filtered at the cable modem(bridge). Does anyone know if this assumption is true and the inside details of the how data is transmitted over the cable network? A link to a whitepaer would be great. thanks >>>>>>>>>>>>> Confidentiality Disclaimer >>>>>>>>>>>> Confidentiality Disclaimer >>>>>>>>>>>> Confidentiality Disclaimer <<<<<<<<<<<<<<<< This email and any files transmitted with it may contain confidential and /or proprietary information in the possession of WellStar Health System, Inc.
