This paper presents Bea Beaver, a method and architecture to "Build dams" to protect servers from Denial of Service (DoS) attacks. Beaver allows efficient filtering of DoS traffic using lo low-cost, high-performance, readily-available packet filtering mechanisms. Beaver improves on previous solutions by not requiring cryptographic processing of messages, allowing the use of efficient routing (avoiding overlays), and establishing keys and state as needed. The paper presents two prototype implementations of Beaver, one as part of IPSec in a Linux kernel, and a second as an NDIS hook driver on a Windows machine.
