Personal profile

My current research focuses on the detection and mitigation of DDoS attacks, DNS security and, more general, Internet security. Topics that my Ph.D. students are working on include amongst others booters, IPv6 security, anycast techniques as well as DNS data analyses.  The approach taken is often measurement-based, including flow (IPFIX) measurement. My earlier research focussed on network management technologies.

Fingerprint Fingerprint is based on mining the text of the person's scientific documents to create an index of weighted terms, which defines the key subjects of each individual researcher.
