Balanced Indexing Method for Efficient Intrusion Detection Systems

摘要

To protect a network from malicious activities, intrusion detection systems can be used. Most of intrusion detection systems examine incoming packets with detection signatures to detect potential malicious packets. Because the portion of malicious packets is usually very small, it is not efficient to examine incoming packets with all signatures. In this paper, we propose a method that reduces the number of signatures to be examined and show the experimental results of our proposed method.
