Distributed Denial of Service (DDoS) attack is a critical threat to the Internet. Recently, the authors proposed the PacketScore scheme, a DDoS defense architecture that supports automated attack detection, online attack characterization and attack blocking. Its key idea is to use a statistics-based packet scoring mechanism to distinguish between legitimate and non-legitimate packets and discard packets based on the packet scores. The threshold used for the score-based selective packet discard decision is dynamically adjusted based on the score distribution of recent incoming packets.
