Very good book for security policy enablers and admins . This is one of the few books that I have come across that focuses mainly on the innards of security assessments. The services based security and counter measures are helpful for threat modeling. This book is really great for people in the security risk and threat analysis for a quantitative and qualitative validation. Good book to help in setting up corporate security policy model. Other people have already provided a good chapter wise run-down so I will skip that here... Buy this book :)
