Characterizing the Performance of NIDS

I just finished reading an interesting paper in which the authors measure and compare two major components of the Network Intrusion Detection System (NIDS) processing cost on a number of diverse systems to pinpoint performance bottlenecks and to determine the impact of operating system and architecture differences.

Suprisingly the results show that even on moderate-speed networks, many systems are inadequate as NIDS platforms. You should read it for yourself to make your own interpretation.

Happy reading.
