Security Onion Documentation

Doug and his team have created the best NSM tool I've had the pleasure to work with. Security monitoring and SIEM tools normally cost a small fortune in licensing, but Security Onion is not only open-source and free, it is more functional 'straight out of the box' than any of the major commercial solutions I've used.This book is the definitive guide to installing, configuring and tuning Security Onion and for me, it is indispensable. There is a lot of documentation on the web, but nothing beats having an actual book to scribble your own notes on.Highly recommended for Cyber professionals!
