Detecting Network Intrusions Using Signal Processing With Query-Based Sampling Filter
Source: National Taiwan University
This paper presents a novel approach for training a network intrusion detection system based on a Query-Based Sampling (QBS) filter. The proposed QBS filter applies the concepts of data quantization to signal processing in order to develop a novel classification system. Through interaction with a partially trained classifier, the QBS filter can use an oracle to produce high-quality training data. It tested the method with a benchmark intrusion dataset to verify its performance and effectiveness. Results show that selecting qualified training data will have an impact not only on the performance but also on overall execution (to reduce distortion).
