This book provides a comprehensive overview on cybersecurity education and training methodologies. The book uses a combination of theoretical and practical elements to address both the abstract and concrete aspects of the discussed concepts. The book is structured into two parts. The first part focuses mainly on technical cybersecurity training approaches. Following a general outline of cybersecurity education and training, technical cybersecurity training and the three types of training activities (attack training, forensics training, and defense training) are discussed in detail. The second part of the book describes the main characteristics of cybersecurity training platforms, which are the systems used to conduct the technical cybersecurity training activities. This part includes a wide-ranging analysis of actual cybersecurity training platforms, namely Capture The Flag (CTF) systems and cyber ranges that are currently being used worldwide, and a detailed study of an open-source cybersecurity training platform, CyTrONE. A cybersecurity training platform capability assessment methodology that makes it possible for organizations that want to deploy or develop training platforms to objectively evaluate them is also introduced. This book is addressed first to cybersecurity education and training practitioners and professionals, both in the academia and industry, who will gain knowledge about how to organize and conduct meaningful and effective cybersecurity training activities. In addition, researchers and postgraduate students will gain insights into the state-of-the-art research in the field of cybersecurity training so that they can broaden their research area and find new research topics.
