I would have to err on the side of CDR to say that the only difference
in analogy you provided (SSH vs Asterisk) is that people lose much
more $$$$$$$$ in VoIP than they ever did in SSH hacking. So, if this
is an exceptional case bending a rule or two of RFC in favor of
security won't harm specially if it's provided as an
option.
Again:
_Applications are often conceptually distinct from the most
appropriate means of securing them._
Moreover, as Kevin Fleming pointed out, refraining from responding to
invalid credentials while continuing to responding to valid ones
simply shifts the presentation of the information, from the point of
view of the scanner. It doesn't accomplish your goal at all.
After-all, RFC does stand for Referral For Comment as in always
open to be improved.
Adopted ones are standards to be followed.
You're right, though; the IETF SIP working group welcomes incremental
improvements; submit yours and see what they think. If you get your
draft adopted, I am sure Digium would be more than happy to implement
it in chan_sip.
I think it's a good idea if such a security "option" is provided by
default in Asterisk knowing it can save a lot of headache. If
budget is an issue maybe make it a bounty and watch support pouring
in...........
The issue is not lack of resources, but rather that it's conceptually
incorrect behaviour, and that the UAS is the wrong place to solve this
problem.
The best advice that has been given in relation to this topic so far
came from Lee Howard earlier today:
