Re: Prevent hacking cable modems with DOCSIS config files
A few different ways to help ensure. My first way is to *not* use Motorola Surfboards as your primary CPE modems. There is a lot of stuff out there designed to work specifically with Surfboard modems. Do a google search for "uncapping surfboard" - it's scary. I personally have not been able to uncap an RCA cable modem after many hours of trying to do so.
The second is to enable the shared secret in your config file, and on the UBR. Pick a non-dictionary word, and from the cable interface, type "shared secret password" where password is your specific password. Then, type the same password in your config file generator.
There are other little things you can do, but these two do the most for you.
This is actually a pretty cool feature, i didn't even know it existed until I was looking for a solution to advertise a subnet (prefix in BGP talk), only if a certain condition existed. This is exactly what conditional advertisements does
