This Policy Brief summarises key findings from the FIDUCIA cybercrime survey, conducted in selected member states, but it also provides an overview of existing data and research on the prevalence of cybercrimes and the public attitudes towards them. The role of current national and European legislation, policies and practical measures are assessed in terms of their deterrent or preventative effects and the potential role for cross-national cooperation and self-regulation to control or prohibit cybercrime are reviewed.
