TCP SYN DoS Attack prevention on Cisco - There is a potential denial of service attack at internet service providers (ISPs) that targets network devices.

TCP 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.
