Michael Starks from Immutable Security just released his presentation “OSSEC in the Enterprise” (with more than 100 slides). It is very technical and well recommended for everyone interested to learn more about OSSEC.

OSSEC Usage Survey (& get a free OSSEC shirt!)
We need your help. In an effort to better understand how the OSSEC project is being used and look for ways to improve OSSEC moving forward, Trend Micro would like you to participate in a brief survey. Why is this coming from Trend Micro? The OSSEC project has been around since 2003. It was acquired by Third Brigade in 2008, and then Third Brigade was acquired by Trend Micro in 2009.
The first 500 OSSEC users to respond to this survey can provide their contact information to obtain a stylish OSSEC T-shirt that Trend Micro is happy to provide as a token of our thanks, and appreciation for your support of the OSSEC project. (Note: shirts available in Europe, Canada & the US for logistical reasons).
Please visit the following URL to start the 5 minute survey:
Thank you in advance for your participation and ongoing support!
JD McCloud from Praetorian Prefect wrote two articles that explain very well how the agentless monitoring works on OSSEC.
The first one, OSSEC: Agentless to save the day, explains how to setup and use agentless to monitor any remote device via ssh.
The second one, OSSEC: Agentless scripts, goes a bit deeper and explains how they work internally and how you can make your own scripts for agentless monitoring.
Recommended read for every OSSEC user.
