This paper benchmarks UNSW-NB15 as a modern alternative to KDD-99 for A-NIDS.
problem Skewed response distribution and non-stationarity in KDD-99 hamper A-NIDS performance.
method Compared UNSW-NB15 to KDD-99 and NSL-KDD using various classification models and SMOTE oversampling.
result UNSW-NB15 outperforms KDD-99 and NSL-KDD in minority class performance, suggesting it as a better benchmark.
