Today's enterprise networks, major Internet exchange points and international peering points increasingly are being interconnected by high-speed fiber and gigabit Ethernet facilities. While these next-generation environments provide benefits in terms of speed and throughput, they also are brutally efficient at spreading distributed denial of service attacks, viruses and malicious worms that can disrupt network and application servers. The increase in the number and severity of attacks as well as the massive economic costs of malicious worms over the past three years indicate that defenses against these problems need to be improved.
