How to stop basic UDP/any port attack flood?
« on: May 14, 2014, 01:07:39 pm »
Hello,

on server i have config server firewall and iptables. I would like server to be safe from basic UDP flood and any port attack flood.

So i want to ask if you can advice on which setting to lookup or which software to use?

Example CSF mentioned above has this option:
Quote
16. Port Flood Protection
#########################

This option configures iptables to offer protection from DOS attacks against
specific ports. This option limits the number of connections per time interval
that new connections can be made to specific ports.


I have port 22 and 80 protected, but not sure if others are vulnerable to this attack.

will this really protect me from these basic non distributed flood attacks or what do you recommend?
no general writing in my threads please, only helpfull ontopic please
