- I am under DDoS. What can I do? 4 answers
I would like to make sure that my Windows 2008 servers are hardened against DDOS attacks.
There is a Microsoft Technet article on Hardening the TCP/IP stack, but it was last revised in January 2006. There is another article (somewhat duplicative) specifically for Windows Server 2003, but I can't find one for Windows Server 2008.
Does anyone know if these protections are already in place in Windows Server 2008's TCP/IP stack or if they are still relevant?
I found a portion of a book on Safari called Windows Server 2008 TCP/IP Protocols and Services that read:
TCP in Windows Server 2008 and Windows Vista use SYN attack protection to prevent a SYN attack from overwhelming the computer.
TCP in Windows Server 2008 and Windows Vista no longer supports the TcpMaxConnectResponseRetransmissions, SynAttackProtect, TcpMaxHalfOpen, and TcpMaxHalfOpenRetried registry values.
...but I can't find a mention of the other registry values nor a second source for this information.
