Mirko Zorz from Help Net Security did an interview with me regarding OSSEC, how it was created, evolved, etc.
Link to the interview: https://www.helpnetsecurity.com/2009/08/21/qa-ossec-the-open-source-host-based-intrusion-detection-system/
"Daniel B. Cid is the founder of the open source OSSEC HIDS and a principal researcher at Trend Micro. He has a special interest in intrusion detection, log analysis and secure development. In this interview he discusses the the open source host-based intrusion detection system in detail.
Give our readers some background on the OSSEC project. How did it all start and evolve?
OSSEC is an open source HIDS that merges log analysis, file integrity monitoring, rootkit detection and active responses. It started as a side-project to help me solve some problems that I had on a previous job (6-7 years ago)...

Thanks Mirko for the great questions and interview.
