“There are only a few books that I would recommend every security professional keep on the shelf, … this is one of them. It was written by someone who has lived the numbing nightmare of surveying the endlessly proliferating sources of event data in a modern enterprise, of identifying what must be collected, how it should be collected, filtered and stored, and what should be done with it. Most importantly, Maier kept careful notes along the way and has provided a guidebook that will help those of us who follow.”
—Richard Austin, MSC, CISSP, MCSE, Hewlett Packard, in IEEE Cipher, January 2007
“Ultimately the readers are provided with a roadmap and a “how to” guideline leading to the successful implementation of a state-of-the-art auditing and monitoring system. Most will want to read it from cover to cover, and also add it to their bookshelves for frequent reference. …Armed with the knowledge from this book, you will be able to champion and guide your organization through a disciplined and well-defined audit and monitoring project. It isn’t a stretch to be able further to design and implement the system while fulfilling a diverse set of requirements and organizational needs.”
