Effective Anomaly-Based Intrusion Detection with Deep Learning

What is it about?

This study delves into the pressing issue of detecting abnormal activities in rapidly growing network traffic. It focuses on the application of unsupervised deep learning methods combined with a semi-supervised approach to identify unknown cyberattacks using flow-based data. Specifically, it employs Autoencoder and Variational Autoencoder techniques to recognize these threats in network traffic data, which includes both typical and various attack types. The study meticulously assesses the performance of these methods through Receiver Operating Characteristics (ROC) and the area under the ROC curve, comparing them to the One-Class Support Vector Machine. The findings highlight the superior performance of Variational Autoencoder in identifying and mitigating network intrusions, demonstrating its effectiveness in enhancing cybersecurity.
