first think about how adsl works, it's not a shared resource, at the other end of your dedicated line there's a card putting out the broadband signal, all it needs is a modem to pick it up. It doesn't have to be secured.
now a cable connection is a shared resource and needs a user name and password or IP or something to allow it's modem to tap into the signal, by necessity this system is like a huge party line and needs to be secured
No. Try not. Do... or do not. There is no try.
