Welcome to the DaemonEye documentation! This comprehensive guide covers everything you need to know about DaemonEye, a high-performance, security-focused process monitoring system built in Rust.

What is DaemonEye?#

DaemonEye is a complete rewrite of the Python prototype, designed for cybersecurity professionals, threat hunters, and security operations centers. It provides real-time process monitoring, threat detection, and alerting capabilities across multiple platforms.

Key Features#

• Real-time Process Monitoring: Continuous monitoring of system processes with minimal performance impact
• Threat Detection: SQL-based detection rules with hot-reloading capabilities
• Multi-tier Architecture: Core, Business, and Enterprise tiers with different feature sets
• Cross-platform Support: Linux, macOS, and Windows support
• Container Ready: Docker and Kubernetes deployment options
• Security Focused: Built with security best practices and minimal attack surface

Three-Component Security Architecture#

DaemonEye follows a robust three-component security architecture:

1. procmond (Collector): Privileged process monitoring daemon built on the collector-core framework with minimal attack surface
2. daemoneye-agent (Orchestrator): User-space orchestrator with:
   • Embedded EventBus broker for multi-collector coordination via topic-based pub/sub messaging
   • RPC service for collector lifecycle management (start/stop/restart/health checks)
   • IPC server for CLI communication using protobuf over Unix sockets/named pipes
   • Alert management with multi-channel delivery
3. daemoneye-cli: Command-line interface for database queries and system management
   This separation ensures robust security by isolating privileged operations from network functionality while enabling scalable multi-collector architectures with RPC-based lifecycle management.
