OSSEC (Open Source HIDS SECurity) is a free, open-source host-based intrusion detection system (HIDS). It performs log analysis, integrity checking, Windows registry monitoring, rootkit detection, time-based alerting, and active response. It provides intrusion detection for most operating systems, including Linux, OpenBSD, FreeBSD, OS X, Solaris and Windows. OSSEC has a centralized, cross-platform architecture allowing multiple systems to be easily monitored and managed. OSSEC has a log analysis engine that is able to correlate and analyze logs from multiple devices and formats.
OSSEC is compliant with Payment Card Industry Data Security Standard (PCI DSS) requirements.
In June 2008, the OSSEC project and all the copyrights owned by Daniel B. Cid, the project leader, were acquired by Third Brigade, Inc. They promised to continue to contribute to the open source community and to extend commercial support and training to the OSSEC open source community.
In May 2009, Trend Micro acquired Third Brigade and the OSSEC project, with promises to keep it open source and free.
In 2018, Trend released the domain name and source code to the OSSEC Foundation.
- Manager (or server), which is required for distributed network or stand-alone installations.
- Agent, a small program installed on the systems to be monitored.
- Agentless mode, can be used to monitor firewalls, routers, and even Unix systems.
Since 2017, Atomicorp has been running the annual OSSEC Conference, where all active developers and members of the community get together to discuss OSSEC and its future.
The 2019 OSSEC Con was held March 20-21st outside Washington DC. Slides and other materials from the conference are available here.
