Sagan is a high performance, real-time log analysis and correlation engine. It uses a multi-threaded architecture to deliver high performance log and event analysis. Its structure and rules are similar to those of the Sourcefire "Snort" IDS/IPS engine. This provides compatibility with rule management software (Oinkmaster, PulledPork, etc.) and allows Sagan to correlate log events with your Snort IDS/IPS system. Sagan can also write to Snort IDS/IPS databases via Unified2/Barnyard2. Sagan is compatible with all Snort "consoles" including Snorby, Sguil, BASE, and the Prelude IDS framework. It supports many different output formats, log normalization (via liblognorm), script execution on event detection, automatic firewall support via "Snortsam", GeoIP detection/alerting, multi-line log support, time sensitive alerting, and much more.
