This is the first major release since Third Brigade acquired OSSEC and it looks to be a pretty major upgrade. Third Brigade now provides commercial support for OSSEC, but the project remains free and open source software (FOSS).
OSSEC is an open source host based intrusion detection system. It is completely cross platform and works on Unix, Linux, Windows and Mac OS.
