This book is designed to familiarize CIOs, IT managers, and other IT professionals with the language, concepts, and technology of digital identity. As I said, I believe that managing digital identity is one of the most fundamental activities in IT and that a good identity management strategy is the key to not only protecting the enterprise from attack, but, more important, providing flexible access for partners, customers, and employees to needed information and systems.
