Re: Security control in DSL access network

I could add that many of the implementations are done using "professional services" of whoever the manufacturer of the DSLAM is and it is a very simple and weak configuration. They make sure it works and thats it. No attention is given to security or performance in any form. Now, I should also mention that the reason for this is that the providers usually only pay for this basic configuration and think or assume they can do the rest. The problem is that a DSLAM configuration can become so huge once the service start rolling that it is hard for any one to go back a fix the configurations because of the impact it may have to the clients. It is not impossible to fix, it will just have an impact to all the clients arriving to the same DSLAM and this can be counted in tens of thousands of clients. So the solution is to do it right from the beginning.

You probably want to start with the DSL Forum <>
After you get through their technical reports you should be very confused.

A problem you will discover is often the DSL folks don't think they
have any security problems. That all the security issues are with IP
and the ISP.
