IoT Intrusion Detection System (IDS)

Apache Spark MLlib | BoT-IoT Dataset | Real-time Detection

System Status Spark Python React

A production-grade, scalable IoT Intrusion Detection System built with Apache Spark for processing massive network traffic. Train ML models on the BoT-IoT dataset from UNSW Canberra Cyber, achieving near real-time anomaly detection with reproducible ML pipelines.

🎯 Project Overview

This system implements a complete ML pipeline for detecting IoT-based network attacks using:

  • Apache Spark MLlib for distributed ML training
  • BoT-IoT Dataset with realistic attack patterns (DDoS, DoS, Reconnaissance, Theft)
  • Real-time streaming detection with live alert monitoring
  • Full-stack GUI for complete pipeline control

Key Features

✅ Data Ingestion

  • Generate synthetic BoT-IoT dataset with realistic traffic patterns
  • Support for 72M+ records (configurable)
  • Automatic preprocessing and validation

✅ ML Model Training

  • Random Forest (F1 Score: >99%)
  • Decision Tree (F1 Score: ~98%)
  • Naive Bayes (Baseline)
  • Chi-square feature selection (Top 5, Top 10, All features)
  • Hyperparameter tuning (Max Depth, Number of Trees)

✅ Model Evaluation

  • Comprehensive metrics (Accuracy, F1, Precision, Recall)
  • Confusion matrix visualization
  • Model comparison dashboard
  • Training time analysis

✅ Real-time Detection

  • Simulated streaming detection service
  • Live threat alerts with severity levels
  • Attack categorization (DDoS, DoS, Reconnaissance, Theft)
  • Real-time statistics and monitoring

✅ Full GUI Dashboard

  • System overview with key metrics
  • Data ingestion and preprocessing interface
  • Model training configuration
  • Evaluation and comparison tools
  • Live monitoring with real-time alerts
