Title: A new massive DDoS attack and potential defenses
Abstract: In the first part of this talk, I will describe the Crossfire attack – a powerful attack that degrades and often cuts off network connections to a variety of selected server targets (e.g., servers of an enterprise, a city, a state, or a small country) by flooding only a few network links. The Crossfire attack has several distinct characteristics which distinguish it from ordinary DDoS attacks: it is undetectable by any targeted servers and network routers; and its attack persistence can be extended virtually indefinitely. I will demonstrate the attack feasibility using Internet experiments and show its effects on a variety of chosen targets (e.g., servers of universities, US states, East and West Coasts of the US). In the second part of the talk, I will present a collaborative defense mechanism, called CoDef, which enables routers to distinguish low-rate attack flows from legitimate flows, and protects legitimate traffic during botnet attacks. I will present CoDef’s design and evaluate its effectiveness by exploring the domain-level path-diversity of the Internet.
