This report focuses on DNS security, i.e. the area of cybersecurity that covers incidents disrupting the availability, integrity and confidentiality of parts of the DNS ecosystem. It analyses the roles and vulnerabilities of actors in the DNS ecosystem, highlights common misconceptions, and discusses the role of governments in enhancing DNS security. The report notably underlines that there is no panacea for DNS security and that promising technical solutions often come with trade-offs.
