Welcome to the "Sagan Rules" README file

This is the Git repository for the Sagan engine rule sets.  You 
probably won't find these useful unless you're actually using Sagan!

What is Sagan? 
--------------

Sagan is an open source (GNU/GPLv2) high performance, real-time log 
analysis & correlation engine.  It is written in C and uses a 
multi-threaded architecture to deliver high performance log & event 
analysis. The Sagan structure and Sagan rules work similarly to the 
Sourcefire "Snort" IDS 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. Since Sagan can write to Snort IDS/IPS databases via 
unified2/barnyard2, it is compatible with all Snort "consoles". For 
example, Sagan is compatible with Snorby [http://www.snorby.org], 
Sguil [http://sguil.sourceforge.net], BASE, and the Prelude IDS 
framework! (to name a few).

Sagan supports many different output formats,  log normalization 
(via liblognorm),  script execution on event and automatic firewall
support via "Snortsam" (see http://www.snortsam.net).
