SYN DoS Attack prevention on Cisco - There is a potential denial of
service attack at internet service providers (ISPs) that targets network
SYN attack: A sender transmits a volume of connections that cannot be
completed. This causes the connection queues to fill up, thereby denying
service to legitimate TCP users.
This paper contains a technical description of how the potential TCP
SYN attack occurs and suggested methods for using Cisco IOS software
to defend against it.
