In light of the entry into force of new European legislation on cybercrime, the Author offers some reflections on the necessity for criminal protection of new and emerging legal assets against traditional and innovative forms of aggression. In considering these assets as expressions of new forms of fundamental rights, he proposes to identify a common denominator among the protean definitions of "cybersecurity". In order to achieve this objective, he proposes the adoption of both a 'substantive' and 'prepositional' concept of cybersecurity. This approach facilitates its function as a rational parameter for guiding choices, including those pertaining to criminal policy. However, it is imperative to recognise the necessity for constant dialogue between disciplines. It is submitted that science and technological knowledge should have a significant impact on the formulation of legislation, with a view to fostering mutual interaction for the understanding of different languages.
