## Traffic Monitor Project
The traffic-monitor directory contains a complete eBPF-based network traffic monitoring solution that demonstrates advanced Aya capabilities. This project was developed as a comprehensive example showcasing XDP (eXpress Data Path) packet processing with structured logging and analytics.
### Development History (Branch: ks/claude-dev)
This project was developed through a comprehensive implementation process that included:
#### Phase 1: Core eBPF Implementation
- **eBPF Kernel Program**: XDP-based packet filtering with CIDR range matching
- **Userspace Management**: Program loading, configuration, and event processing
- **Configuration System**: JSON-based CIDR range management
- **Event Handling**: Real-time statistics and traffic analysis
#### Phase 2: Structured Logging Enhancement
- **Multi-Format Logging**: JSON, CSV, JSONL, and Console output formats
- **Performance Optimization**: Buffered I/O and configurable buffer sizes
- **Flow Correlation**: Unique flow hashing for session tracking
- **Metadata Enrichment**: Timestamps, protocol details, and action logging
#### Phase 3: Analytics and Threat Detection
- **Log Analysis Script**: Comprehensive Python-based analytics tool
- **Threat Detection**: Port scanning, high-volume source, and anomaly detection
- **Statistical Analysis**: Traffic patterns, protocol distribution, and flow analysis
- **Export Capabilities**: JSON and CSV report generation
#### Phase 4: Testing and Documentation
- **Comprehensive Testing**: Unit tests, integration tests, and sample data
- **Docker Integration**: Multiple container configurations for testing
- **Demo Infrastructure**: Standalone demos and validation scripts
- **Documentation**: Complete README with usage examples and architecture
