AI-Powered Hierarchical Network Intrusion Detection System | 99.89% Accuracy IDS with Machine Learning & Real-Time Threat Analysis

Advanced Hierarchical Intrusion Detection System - Final Year Project

The Hierarchical Intrusion Detection System (IDS) is a cutting-edge final year project for CSE students that implements a sophisticated three-level machine learning classification approach to detect and categorize network security threats with industry-leading accuracy. Unlike traditional flat multi-class classification systems, this hierarchical approach minimizes dangerous false negatives and provides precise attack categorization, making it ideal for cybersecurity final year projects and research applications.

Project Overview & Problem Statement

With the rapid adoption of IoT devices and cloud technologies, cyberattacks have become increasingly sophisticated and frequent. Traditional intrusion detection systems using flat classification often misclassify malicious network traffic as benign (false negatives), which is more dangerous than mislabeling attack types. This project solves this critical problem by implementing a hierarchical classification model with 99.89% detection accuracy.

Key Features of This Final Year Project

Research & Innovation

This project is based on recent research findings demonstrating that hierarchical classifiers minimize false negatives compared to flat multi-class classification. The hierarchical approach ensures that even if the system misclassifies an attack type, it rarely misidentifies attacks as normal traffic - a critical advantage in high-security environments.
