Thesis Abstract

Abstract
The rapid growth of network communication technologies has led to an increase in the complexity and volume of network traffic data. As a result, the detection of anomalies in network traffic has become a critical task for ensuring the security and reliability of network systems. Traditional rule-based methods for anomaly detection have limitations in detecting unknown or evolving network threats. In contrast, machine learning algorithms have shown promising results in identifying anomalous patterns in network traffic data.
