First thing I'd do is restrict the ip blocks your sip endpoints can
register/call from in sip.conf (or your database's table for sip
endpoints)

Thanks for the idea, but it's not possible, as the Asterisk must be
accessible for road warriors and receive SIP calls from anyone.
Really? How many callers are you expecting from North Korea, Libya,
China, Iran, etc?
Thanks Steve, you just emailed exactly what I was going to say...
Remember guys, there's a LOT of IP blocks out there that are almost
definitely not going to be somewhere you expect to receive SIP traffic
from.
Well, I can tell you that our servers in europe those days are mainly
attacked by US IP ranges (remember last year the problem with amazon
cloud). They now disappear here in europe but lots of other US networks
quickly replace them :-(
