Devs,

I'm looking for some advice/opinions.

Regarding security of the dmq messages between kamailios - currently it can be achieved by using a separate port (and/or ip) for dmq use and locking this down at firewall level. Of course, tls can be used to protect the content of the messages over the wire.

So is this enough? Or should I look to implement some kind of authentication mechanism as well? Perhaps something as simple as a pre-shared key would suffice, assuming the messages are encrypted of course. Full digest authentication is way too heavy in my opinion.

Any ideas? Or just leave it up to the user to secure it in network layer?

Cheers,

Charles
