Today we have recently got "bombared" with a DDOS attack on 2 of our servers that use Plesk. The datacenter will not un-nullroute our servers at the time, We need to find out what is the best procedure in setting up some security on our 2 servers. Does anyone have any good ideas on what we can use or setup on our plesk servers to stop these DDOS attacks that will not effect other software that is on the server?
