A cascaded classifier approach for improving detection rates on rare attack categories in network intrusion detection |

---|---|---|
Network intrusion detection research work that employed KDDCup 99 dataset often encounter challenges in creating classifiers
that could handle unequal distributed attack categories. The accuracy of a classification model could be jeopardized if the
distribution of attack categories in a training dataset is heavily imbalanced where the rare categories are less than 2% of
the total population. In such cases, the model could not efficiently learn the characteristics of rare categories and this
will result in poor detection rates. In this research, we introduce an efficient and effective approach in dealing with the
unequal distribution of attack categories. Our approach relies on the training of cascaded classifiers using a dichotomized
training dataset in each cascading stage. The training dataset is dichotomized based on the rare and non-rare attack categories.
The empirical findings support our arguments that training cascaded classifiers using the dichotomized dataset provides higher
detection rates on the rare categories as well as comparably higher detection rates for the non-rare attack categories as
compared to the findings reported in other research works. The higher detection rates are due to the mitigation of the influence
from the dominant categories if the rare attack categories are separated from the dataset. |
