The rapid escalation of cyber threats and the increasing complexity of network infrastructures have exposed the limitations of traditional signature-based Intrusion Detection Systems (IDS), particularly in detecting zero-day attacks and minimizing false positives. This paper presents an AI-powered real-time intrusion detection framework that integrates supervised and unsupervised machine learning techniques to enhance detection accuracy and adaptability. The proposed system employs Random Forest for multi-class classification of known attack patterns and Isolation Forest for anomaly detection of previously unseen threats. The models are trained and evaluated using the NSL-KDD benchmark dataset, achieving detection accuracies of 98.2% and 96.5% respectively, significantly outperforming conventional approaches.
To ensure practical applicability, the system incorporates a real-time traffic analysis pipeline using Wireshark, a preprocessing module for feature engineering and normalization, and a graphical user interface for live threat visualization. Additionally, SIEM-compatible log generation enables seamless integration with Security Operations Center (SOC) workflows for efficient monitoring and response. The experimental results demonstrate that the proposed hybrid framework not only improves detection performance but also provides scalability and real-time capabilities required for modern network security environments. This work highlights the potential of combining machine learning with real-time analytics to build intelligent and proactive intrusion detection systems.
