With recent advances in IT in areas such as AI and IoT, collaboration systems such as business chat, cloud services, conferencing systems, and unified communications are rapidly becoming widely used as new IT applications in global corporations' strategic activities. Through in-depth longitudinal studies of global corporations, the book presents a new theoretical framework and implications for IT-enabled dynamic capabilities using collaboration systems from the perspective of micro strategy theory and organization theory. The content of the book is based on longitudinal analyses that employ various qualitative research methods including ethnography, participant observation, action research and in-depth case studies of global corporations in Europe, the United States and Asia that actively use collaboration systems. It presents a new concept of micro dynamism whereby dynamic "IT-enabled knowledge communities" such as "IT-enabled communities of practice" and "IT-enabled strategic communities" create "IT-enabled dynamic capabilities" through the integration of four research streams - an information systems view, micro strategy view, micro organization view and knowledge-based view. The book demonstrates that collaboration systems create, maintain and develop "IT-enabled knowledge communities" within companies and are strategic IT applications for enhancing the competitiveness of companies in the ongoing creation of new innovation and the realization of sustainable growth in a 21st century knowledge-based society. This book is primarily written for academics, researchers and graduate students, but will also offer practical implications for business leaders and managers. Its use is anticipated not only in business and management schools, graduate schools and university education environments around the world but also in the broad business environment including management and leadership development training.

Enterprise Level Security 2: Advanced Topics in an Uncertain World follows on from the authors' first book on Enterprise Level Security (ELS), which covered the basic concepts of ELS and the discoveries made during the first eight years of its development.

175+ Cybersecurity Misconceptions and the Myth-Busting Skills You Need to Correct Them Cybersecurity is fraught with hidden and unsuspected dangers and difficulties. Despite our best intentions, there are common and avoidable mistakes that arise from folk wisdom, faulty assumptions about the world, and our own human biases. Cybersecurity implementations, investigations, and research all suffer as a result. Many of the bad practices sound logical, especially to people new to the field of cybersecurity, and that means they get adopted and repeated despite not being correct. For instance, why isn't the user the weakest link? In Cybersecurity Myths and Misconceptions: Avoiding the Hazards and Pitfalls that Derail Us, three cybersecurity pioneers don't just deliver the first comprehensive collection of falsehoods that derail security from the frontlines to the boardroom; they offer expert practical advice for avoiding or overcoming each myth. Whatever your cybersecurity role or experience, Eugene H. Spafford, Leigh Metcalf, and Josiah Dykstra will help you surface hidden dangers, prevent avoidable errors, eliminate faulty assumptions, and resist deeply human cognitive biases that compromise prevention, investigation, and research. Throughout the book, you'll find examples drawn from actual cybersecurity events, detailed techniques for recognizing and overcoming security fallacies, and recommended mitigations for building more secure products and businesses. Read over 175 common misconceptions held by users, leaders, and cybersecurity professionals, along with tips for how to avoid them. Learn the pros and cons of analogies, misconceptions about security tools, and pitfalls of faulty assumptions. What really is the weakest link? When aren't "best practices" best? Discover how others understand cybersecurity and improve the effectiveness of cybersecurity decisions as a user, a developer, a researcher, or a leader. Get a high-level exposure to why statistics and figures may mislead as well as enlighten. Develop skills to identify new myths as they emerge, strategies to avoid future pitfalls, and techniques to help mitigate them.
