M. (TU Delft Cyber Security; SIDN Labs) Contributor Charalambides, Marinos (editor) Papadimitriou, Panagiotis (editor) Cerroni, Walter (editor) Kanhere, Salil (editor) Mamatas, Lefteris (editor) Date 2022 Abstract Electronic government (e-gov) enables citizens and residents to digitally interact with their government via the Internet. Underpinning these services is the Internet Domain Name Systems (DNS), which maps e-gov domain names to Internet addresses. Structuring DNS with multiple levels of redundancy that can withstand stress events such as denial-of-service (DoS) attacks is a challenging task. While the operator community has established best practices to this end, adopting them all involves expert knowledge and resources. In this work, we obtain and study a list of e-gov domain names used by four countries (The Netherlands, Sweden, Switzerland, and the United States) and measure the DNS structuring of these domains. We show the adoption of best practices, inter-country differences such as the use of anycast, and provide recommendations to improve DNS service robustness.
