IoT Intrusion Detection System (IDS)

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

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

• 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
