I was glad to read that Richard Bejtlich considered the OSSEC book one of his best reads of 2008. From the post:
by Rory Bray, Daniel Cid and Andrew Hay. I have to congratulate the author team for OHG. Writing a book for Syngress with many contributors is usually a recipe for disaster. OHG features three lead authors, four contributors, and one foreword author — and they don’t step on each others’ toes.
