- Network Intrusion Detection Systems (NIDS) face challenges due to class imbalance, affecting their ability to detect novel and rare attacks. This paper proposes a Dual-Conditional Batch Normalization Variational Autoencoder ($\text{C}^{2}\text{BNVAE}$) for generating balanced and labeled network traffic data. $\text{C}^{2}\text{BNVAE}$ improves the model's adaptability to different data categories and generates realistic category-specific data by incorporating Conditional Batch Normalization (CBN) into the Conditional Variational Autoencoder (CVAE). Experiments on the NSL-KDD dataset show the potential of $\text{C}^{2}\text{BNVAE}$ in addressing imbalance and improving NIDS performance with lower computational overhead compared to some baselines.
