This document summarizes research on using various data mining classification techniques to handle false alerts in intrusion detection systems. The researchers tested many data mining procedures on the KDD Cup 99 dataset, including multilayer perceptron neural networks, rule-based models, support vector machines, naive Bayes, and association rule mining. The best accuracy was 92% for multilayer perceptrons, but rule-based models had the fastest training time at 4 seconds. The researchers concluded that different techniques should be used together to handle different types of network attacks.
