I would like to know how resilient a Windows server is to TCP SYN flood attacks. I know modern Linux kernels have SYN cookies which makes it pretty much invincible to SYN flood, but Windows seem to lack this feature. So my question is: now to determine how many packets per seconds an attacker would need to send to disrupt a service?
I have found information about how to harden the network stack http://support.microsoft.com/kb/324270
. Ok, it makes the server more resilient to an attack, but how resilient?
