This book is aimed at managerial decision-makers, practitioners in any field, and the academic community. The chapter authors have integrated theory with evidence-based practice to go beyond merely explaining cybersecurity topics. To accomplish that, the editors drew upon the combined cognitive intelligence of 46 scholars from 11 countries, to present the state-of-the-art in cybersecurity. Managers and leaders at all levels in organizations around the globe will find the explanations and suggestions useful for understanding cybersecurity risks as well as formulating strategies to mitigate future problems. Employees will find the examples and caveats both interesting as well as practical for everyday activities, at the workplace and in their personal lives. Cybersecurity practitioners in computer science, programming, or espionage will find the literature and statistics fascinating and more than likely a confirmation of their assumptions. Government policymakers will find the book valuable to inform their new agenda of protecting citizens and infrastructure in any country around the world. Academic scholars, professors, instructors, and students will find the theories, models, frameworks, and discussions relevant to support teaching as well as research.
