The traditional IDS, lots of work should be done on the computer where the event analyzer had been established. It made this computer become bottleneck in system, and had affected the performance of IDS. In order to solve this problem, we present a new CIDF_Based IDS. In our IDS, we had improved the event analyzer by using 2-stage processing technology and parallel processing technology. The improved IDS accelerated the data analysis speed, improved the ability of intrusion tolerance, and reduced the false positives rate and false negatives rate.
