A New Approach to DDOS Attack Defense Using the Survivability Concept of Router

In this paper, we present a new form of DDOS attack and a mechanism to defend systems from it. Up to now the ultimate target of a DDOS attack is a specific host. But in the near future router attacks are expected to appear. Because these kinds of attacks may involve many hosts in the managed domain of a specific router, they will be still more serious than the current DDOS attacks. Also, we present an algorithm to defend against an attack on a router using survivability of the router. By using a survivability of a router, the router can control a quantity of traffic autonomously without an interruption of services even when a DDOS attack occurs.
