About Me

I’m full professor of measurement-based Internet Security in the Design and Analysis of Communication Systems (DACS) group at the Faculty of Electrical Engineering, Maths and Computer Science (EEMCS) at the University of Twente.

My research focuses on defending the Internet against malicious activity and on strengthening the security and resilience of the Internet by improving protocols and operations, and the deployment of new security protocols and mechanisms. I use an empirical approach to these challenges by performing global Internet-scale passive and active measurements.

Research

My research focuses on defending the Internet against malicious activity and on strengthening the security and resilience of the Internet by improving protocols and operations, and the deployment of new security protocols and mechanisms. I use an empirical approach to these challenges by performing global Internet-scale passive and active measurements.

I currently have two particular areas of interest:

  • The Domain Name System (DNS) – after IP, DNS is the most critical protocol on the Internet, without which the Internet effectively stops working for most users. I explore the security of the DNS using large scale measurements and statistical analysis, for instance studying the effects of the deployment of the DNS Security Extensions (DNSSEC), both in the positive (added security) and the negative (larger potential for abuse in DDoS attacks) sense. DNS also plays an important role in other security issues on the Internet, such as botnets, phishing and malware.
  • Routing Security (RPKI) – much like other early core protocols of the Internet, the interdomain routing protocol BGP was not designed with security in mind. The Resource Public Key Infrastructure (RPKI) aims to remedy this by allowing resource holders to manage authorizations for their resources. Apart from having an interest in the gradual deployment of this technology on the global Internet, I am also interested in studying new applications that further enhance the security of the routing ecosystem.

My research is supported by SURF, the collaborative organisation for ICT in Dutch higher education and research, by the Netherlands Organisation for Scientific Research (NWO), by SIDN Fonds and by European Commission Framework Project grants.

Education

In the bachelor, I'm on the teaching team for the High-Tech Human Touch minor on Cybersecurity and Cybercrime, in which I teach the basics of Privacy and Information Security. In the master I teach courses on Internetworking, such as Internet Measurements and Advanced Networking.

I also regularly supervise bachelor and master theses, if you're looking for a topic feel free to contact me or drop by my office. I have an extensive network in industry, both in the Netherlands and abroad, so if you're looking for an internship assignment or an external master topic you can also contact me.
