Sagan is billed as the advanced Suricata/Snort like log analysis engine.
It uses a multi-threaded architecture to deliver high performance log & event analysis. Sagan’s structure and rules work similarly to the Snort or Suricata IDS/IPS engines. It maintains compatibility with rule management software (oinkmaster/pulledpork/etc) and allows Sagan to correlate log events with your Snort/Suricata IDS/IPS system.
Sagan is free and open source software.
Key Features
- Automate log management:
- Supports many different output formats.
- Log normalization.
- Script execution on event detection.
- GeoIP detection/alerting.
- Multi-line log support.
- Time sensitive alerting.
- Multi-threaded architecture allows it to use all CPUs / cores for real-time log processing.
- CPU and memory resources are lightweight.
- Built in JSON parsing.
- Similar rule syntax to Cisco’s “Snort” which allows for easy rule management and correlation with Snort or Suricata IDS / IPS systems.
- Store alert data in Cisco’s “Snort” native “unified2” binary data format or Suricata’s JSON format for easier log-to-packet correlation.
- Intra-Process communications between Sagan processes to share data. Sagan can also use Redis (beta) to share data between Sagan instances within a network.
- Compatible with popular graphical-base security consoles like Snorby, BASE, Sguil, and EveBox.
