Partly because of old versions of PIAF I've been a very occasional CentOS user and I've never used Debian before.
I've installed PIAF5 / 3CX on a Debian VPS recommended by 3CX at OVH. It's local and cheap. (Sorry Ward!)
The installation works and passes the built in 3CX firewall test - but I'm guessing that is checking the necessary ports are open and not checking the machine is secure. Is that correct?
How do I ensure the server is secure? What do I need to do to lock it down? By default does the Debian installation provision in a safe way, or does it have no firewall turned on at all?
PIAF has always been hot on VOIP security so I'd welcome advice from the community and/or Nick at 3CX. Is there a resource for this I have missed?
