Hello In a ddos syn flood attack in a fast server: # 2x Intel Xeon Quad 5405 # 8192 MB FB DDR2 RAM # 500 GB 7.200 RPM # 1.000 Mbit unshared port I want to ask if the problem will be the cpu ram or the network card to hold as much traffic is possible for a forum? Thank you
Depends on what services they are flooding, if it's web pages, what web pages they are flooding. If they are hitting pages that are generated dynamically, your first bottleneck will probably be your DB server's inability to do that many SQL queries. If they are not hitting dynamically generated pages, your first bottleneck will probably be the number of concurrent requests your web server can fulfill.
Thank for you fast responce digitalpoint What i can do for those two scenarios to protect my server or to be able to handle that? Does extra ram helps the performance of my sql in tha scenario?
Not really, no... your best bet is to block it before it gets to your server (at the firewall or router level).
