Lessons include discussions of the key design objectives and then provide evaluations of possible decisions to be made within each design objective, and each lesson ends with a lesson summary. The activities and labs are designed to allow you to practice or demonstrate your understanding of the design objectives discussed within a chapter. Each chapter ends with a set of review questions to test your knowledge of the chapter material. Within each chapter a common scenario will be used to illustrate the design decisions you face when designing Windows 2000 security.
