Left me wanting more
By S. May
The content is great. I would suggest anyone that is going to install or use OSSEC to start here. Like my title suggests though. This is just a starting point. There is a lot more to learn that this book will not give you just keep in mind this is a starting point. A really good starting point.

For hands-on persons who are comfortable pushing the envelop using XML, regular expression, and shell scripts
By JB Cheng
It tells you how to install OSSEC for both manager and agents, and how to generate agent keys so agents and talk to the manager securely. It uses examples to explain how OSSEC rules work, and illustrates step-by-step how you can write your own custom decoders/rules and test them to verify that they work as expected. It goes further to describe how you can fine tune alert levels so you are not flooded with too many alerts, as well as how you can channel OSSEC output to third party log management systems in several de-facto standard formats.
Another key feature of OSSEC, syscheck, is useful to perform integrity monitoring for files, directories, and Windows registry entries. Syscheck can also be extended to monitor the output of arbitrary commands by treating the output as log entries. A case-in-point is the implementation of OSSEC rootcheck, which utilizes the syscheck framework for rootkits detection. OSSEC ships with a default set of rootcheck rules; user extension is possible so you can be alerted with the newest threats.
Finally, OSSEC active response is one step toward Host-based Intrusion Prevention System by using alerts to trigger defensive actions such as blocking traffic from offending IP addresses automatically. This book concludes by giving a scripting example of verifying alerts with active response. It pulls everything together and unleashes the full potential of OSSEC. With the scripting capability of OSSEC active response feature, the possibilities are endless.

Excellent book for learning how to use OSSEC
By Vic Hargrave
Brad's book "Instant OSSEC Host-based Intrusion Detection System" is a great place for new users of OSSEC to start with the process of understanding what OSSEC does and how to configure it. The book consists of a series of what I like to call "recipes" that ranges from basic information such as installing OSSE to advanced concepts like detecting rootkits and configuring active response - the OSSEC mechanism to take user defined actions to handle specific security events. Each recipe follows a consistent format that describes background information you need to know, how to do the particular recipe and even how each works.
I work with Brad on the OSSEC Project development team, so I'm no stranger to using OSSEC. But OSSEC has a lot of capabilities, not all of which I have used, so I found Brad's book very helpful in understanding some of the core functionality with which I had less experience. If you are an OSSEC beginner or like me, someone who is familiar with it but could use some help with more advanced features, then you'll want to have "Instant OSSEC Host-based Intrusion Detection System" right by your side at all times.
