Ossec

The OSSEC project is currently maintained by Atomicorp who stewards the free and open-source version and also offers an enhanced commercial version. However, the main pain point of this tool is that it lacks some of the core log management and analysis components of a typical SIEM. This limitation motivated other HIDS solutions like Wazuh to fork OSSEC in order to extend and enhance its functionality and make it a more complete SIEM tool. However, in recent times, Atomicorp has made a lot of changes, upgrades, and enhancements to OSSEC, which has repositioned it to be more competitive.

The MozDef architecture is designed in a way that does not allow log shippers (rsyslog, syslog-ng, beaver, nxlog, heka, logstash) direct access to Elasticsearch. Rather, MozDef places itself between Elasticsearch and the log shippers, thereby making it possible for log shippers to interact directly with MozDef as shown in the diagram below. This makes MozDef different from other log management tools that use Elasticsearch and enables it to provide basic and advance SIEM functionalities such as event correlation, aggregation, and machine learning.
