The evolution of sixth-generation (6G) wireless networks introduces a complex landscape of cybersecurity challenges due to advanced infrastructure, massive device connectivity, and the integration of emerging technologies. Traditional intrusion detection systems (IDSs) struggle to keep pace with such dynamic environments, often yielding high false alarm rates and poor generalization. This study proposes a novel and adaptive IDS that integrates statistical feature engineering with a deep autoencoder (DAE) to effectively detect a wide range of modern threats in 6G environments. Unlike prior approaches, the proposed system leverages the DAE’s unsupervised capability to extract meaningful latent representations from high-dimensional traffic data, followed by supervised classification for precise threat detection. Evaluated using the CSE-CIC-IDS2018 dataset, the system achieved an accuracy of 86%, surpassing conventional ML and DL baselines. The results demonstrate the model’s potential as a scalable and upgradable solution for securing next-generation wireless networks.
