I would really appreciate if anyone of you could give me some information (or even pointers) regarding DoS attacks and Asterisk.
My question is what has been done so far in securing Asterisk from DoS attacks?
I just downloaded couples of DoS attack tools from hackingvoip.com (one of them is inviteflood). BAsically, inviteflood will flood asterisk with SIP-invite messages. And it worked. My Asterisk machine is not functioning; placing a call is impossible, etc…
So, I am planning to solve this problem and need more information if anything has been done regarding this so far.
btw, I am running Fedora 7 with ASterisk 1.4.8.
