How to stop HPING3 flooding ICMP/UDP/TCP against firewall or passing through it
Yesterday night I was playing with HPING3 tool. And I realized I could freeze my TZ300 with a flood attack.
I have searched for any article on the Sonicwall knowledge base that could give me some ideas to stop an attack like this one.
Of course, I have enabled IPS/IDS and I also configured some parameters on "Firewalls Settings / Flooding Protection"
On the other hand, whats would happen if my target is a published service on the firewall? I mean, a server behind the firewall listening on port TCP 80, for example.
Any help on this, please?
