I must admit, as a Nessus user for many many years now, I was excited to hear that a publication was finally becoming available on Nessus (isn't one astonished of how many actual Cisco/Microsoft/Java books exist). However, I was "pensive at best" when it came to actually purchasing a book that "appeared" to simply convey how to install/configure/run this award-winning IT Security tool.
To my pleasant surprise, the very evening I purchased the book, I found myself unable to put this book down, and in fact, stayed up nearly all night reading the entire thing. My overall rating? The best investment I'd spent for an IT Security book in several years. Hands down!
Thankfully, only about 1/3 of the book is spent on install/configure/running the product, the other 2/3rds of the publication convey keen insights surrounding the ins and outs of vulnerability assessments.
I submit that all IT Security Engineers should spent the money and time gaining "keen insights and perspectives" of Renaud Deraison, unquestionably a pioneer in the history of IT Security. True, a vulnerability assessment is only one (yet key) piece of the entire "Security Puzzle", nevertheless, if your job carries the title CISSP/CISM, and you're involved with IT Security (regardless of whether or not your vulnerability assessment tool du jour is Nessus or not) your understanding surrounding vulnerability assessments isn't complete til you've peered into the "Mind's eye" of Mr. Deraison.
Clearly, in the annals of IT Security, history will render him a Pioneer in the journey of protecting an organizations IT assets.
