nCMD: Benign-Anchored Feature Selection for Imbalanced Network Intrusion Detection
Researchers have developed a new feature selection method called benign-anchored Classwise Mean Deviation (nCMD) specifically for network intrusion detection systems. This method addresses the challenge of imbalanced data by focusing on how attack distributions deviate from the normal, benign traffic. In evaluations across four benchmark datasets, nCMD matched or surpassed traditional methods in identifying intrusions, particularly under conditions of severe class imbalance and limited feature budgets.
