Denial of Service Protection with Beaver
We present Beaver, a method and architecture to ``build dams\u27\u27 to
protect servers from Denial of Service (DoS) attacks. Beaver allows
efficient filtering of DoS traffic using 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. We present 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.
Preliminary measurements illustrate that Beaver withstands severe
DoS attacks without hampering the client-server communication.
Moreover, Beaver is simple and easy to deploy
