The Sagan Log Analysis Engine


Sagan 1.0.0 has been released!  See our Sagan 1.0.0 release page for more details! 

What is Sagan?

Sagan is an open source (GNU/GPLv2) high performance, real-time log analysis & correlation engine that run under *nix operating systems (Linux/FreeBSD/OpenBSD/etc). It is written in C and uses a multi-threaded architecture to deliver high performance log & event analysis. Sagan's structure and rules work similarly to the Sourcefire/Cisco"Snort" IDS/IPS engine. This was intentionally done to maintain 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". For example, Sagan is will work with Sguil ( http://sguil.sourceforge.net ), BASE, the Prelude IDS framework ( https://www.prelude-ids.org ) and proprietary consoles! (to name a few).
Sagan supports many different output formats, log normalization (via http://www.liblognorm.com), script execution on event detection, automatic firewall support via "Snortsam", GeoIP detection/alerting, multi-line log support (flowbit), time sensitive alerting and much more.
The development of Sagan is sponsored by Quadrant Information Security Team.
