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

Sagan is an open source (GNU/GPLv2) high performance, real time log
analysis & correlation engine. It's written in C and uses a
multithreaded architecture to deliver high performance log & event
analysis. Sagan rules and structure work similar to Sourcefires
?Snort? IDS engine. This is done to maintain compatibility with rule
management software (oinkmaster/pulledpork/etc) and allows Sagan the
ability to correlate log events with your Snort IDS/IPS system.
Since Sagan can write to Snort IDS/IPS databases via
unified2/barnyard2 or direct SQL access, it's compatible with all
Snort ?consoles?. For example, Sagan works fine with Snorby
[http://www.snorby.org], Sguil
[http://sguil.sourceforge.net] and the Prelude IDS framework! For more
information, please visit the Sagan web site:

What's new in Sagan?
- --------------------

- - This release is largely a bug fix for the Sagan "after:" directive.
Older verions of Sagan (0.2.1--) incorrectly handled the "after:"
flag/directive. New versions of the Sagan rules make heavy use of
"after:". In one week we'll be pushing out a major rule set update.
This new rule update will potentially break 0.2.1-- clients. Please
upgrade ASAP.

- - Added content negation at the request of DigAngel. This means you
can do things like:

content: "Find this"; content: ! "But don't find this";

- - Several other minor bug fixes.

What's in the future for Sagan?
- -------------------------------

- - New pre-processors for log analysis for better anomaly detection.
- - Better multi-CPU support on CPU intensive operations.

Where's an online demo?
