sagan - 1.2.0-1.2 main

Sagan is a multi-threaded, real time system- and event-log monitoring
system, but with a twist. Sagan uses a “Snort” like rule set for
detecting malicious events happening on your network and/or computer
systems.
If Sagan detects a potentially bad event, that event can be stored to a
Snort database (MySQL/PostgreSQL), send it to a SIEM tool like Prelude,
or send an email.
Sagan is meant to be used in a ‘centralized’ logging environment, but
will work fine as part of a standalone Host IDS system for workstations.
