Companies are exposed to risks of various origins that can significantly disrupt their operations in the event of a security-critical incident. Therefore, the task of corporate security is to prevent these incidents as much as possible or to effectively combat them after they occur. This book comprehensively and systematically presents the necessary structural, technical, and organizational measures to ensure safe corporate operations. It serves as a valuable resource for practitioners in companies, consulting firms, insurance companies, and authorities, as well as for students in relevant degree programs. By addressing all relevant hazards and measures, as well as fundamental methodological questions, it is ideally suited as a foundation for developing company-specific security concepts.
