Languages : en
Pages : 66
Book Description
"How do you think like a manager?" It is one of the most common questions asked when preparing for the CISSP exam. Using 25 CISSP practice questions with detailed explanations, this book will attempt to answer how to think like a member of a senior management team who has the goal of balancing risk, cost, and most of all, human life. The questions will take you through how to resist thinking from a technical perspective to one that is more holistic of the entire organization. Like all of Study Notes and Theory's CISSP practice questions, these questions correlate multiple high-level security concepts and require thinking like a manager. Extracting the most value comes from understanding not only which choice is correct, but more importantly, why the other choices are wrong.
