Abstract

A system protects communicaton networks and devices against denial of service (DoS) attacks. A service provider (116) receives a signal indicating that a DoS attack has been detected, receives one or more packets intended for a victim device (420), and transmits the one or more packets to a triage device (140). The triage device determines whether each of the one or more packets is part of the DoS attack and forwards only packets that are deemed unrelated to the DoS attack to the victim device (420).
