Network processor based network intrusion detection system

Abstract

To achieve fast packet processing and dynamic adaptation of intrusion patterns that are continuously added, a new high performance network intrusion detection system using Intel's network processor, IXP1200, is proposed. Unlike traditional intrusion detection engines, 49 which has been implemented by either software or hardware so far, we propose an optimized architecture and algorithms, exploiting the features of network processor. Through implementation and performance evaluation, we show the proprieties of the proposed approach.
