You are the system administrator for a provider that owns a large network (e.g., at least 64,000 IP addresses). Show how you can use SYN cookies to perform a DOS attack on a web server
What will be an ideal response?
The rogue administrator initiates a large number of TCP connections to the
web server spoofing source IP addresses from his network. Also, he intercepts the SYN
ACK responses from the server and sends back spoofed ACKs to complete the handshakes
for these connections. The web server has now created a large number of sessions that will
remain open, using up resources, until they time out. This attack works even if the web
server uses SYN cookies.
