OSSEC HIDS is an open source host-based intrusion detection system. It performs log analysis, integrity checking, rootkit detection, time-based alerting and active response.

This is one of the most improved versions so far. It now includes support for squid, pure-ftpd, postfix and AIX ipsec logs (in addition to a lot of improvements to the previous rules).

The integrity checking engine now allows granular options, where you can specify exactly what options you want to monitor (checksum, size, ownership, etc).

The rootkit detection had a lot of improvements too, reducing false positives on most of the systems and with a lot of new anomaly checks to detect kernel level rootkits.

We also have a new website and the installation in 4 different languages (portuguese, english, german and turkish). <P. In addition to that, this version includes a lot of bug fixes and performance improvements.
