OSSEC watches it all, actively monitoring all aspects of Unix system activity with file integrity monitoring, log monitoring, rootcheck, and process monitoring. With OSSEC you won't be in the dark about what is happening to your valuable computer system assets.

When attacks happen OSSEC lets you know through alert logs and email alerts sent to you and your IT staff so you can take quick actions. OSSEC also exports alerts to any SIEM system via syslog so you can get real-time analytics and insights into your system security events.

OSSEC is fully open source and free for your use. You can tailor OSSEC for your security needs through its extensive configuration options, adding your custom alert rules and writing scripts that take actions in response to security alerts. You are free to modify the source code to add new capabilities.

OSSEC helps customers meet specific compliance requirements as outlined in PCI DSS 1.2/2.0. It lets customers detect and alert on unauthorized file system modifications and malicious behavior based on entries in the log files of COTS products as well as custom applications.
