Re: Excellent!!
said by nitzan  :said by anony101 :Keep in mind however that the only ones who can "listen in" on your calls are your ISP, our ISP, and the phone companies on the way. None of which are going to bother filtering through millions of minutes of call time. That's not accurate. Cable customers can listen in to unencrypted VOIP calls within the same node they're in which means their neighborhood. I could be wrong, but AFAIK your neighbors CANNOT sniff your packets. Unless they have access to the switch - which they don't - they cannot listen in on you. You couldn't do it on the PC side of the cable modem. But if you hook up a device directly to the cable and bypass the cable modem altogether with a sniffer device, you could see and capture the packets on your local node.

So essentially, cable internet is inherently less secure than, say, DSL? or better yet - FTTH? |

| There is no protection against tampering with the signals on the RF cable network.
The main advantages of BPI+ in DOCSIS 1.1 is the capability to upgrade crypto mechanisms in already deployed Cable Modems and the use of digital certificates to authenticate Cable Modems.
Notice also that all setup and configuration of the BPI functions are made at the CMTS, so as a user you have very little control over when your data are encrypted and when they are not. In reality the purpose of BPI and BPI+ is this
* To protect against theft of service

Just because some connections go through the CO first doesn't mean some one can't tap into it along the way.  |
