Professor in Internet Security

About Me

Aiko Pras is full professor in the area of Network Operations and Management with a focus on Internet Security at the Faculty of Electrical Engineering, Mathematics and Computer Science of the University of Twente, the Netherlands. He is member of the Design and Analysis of Communication Systems Group (DACS). In 1995 he received a Ph.D. degree from the same university for his thesis titled "Network Management Architectures" and in 2013 he was appointed as full professor.

Aiko is interested in questions like Digital Independence and Internet security, with a research focus on DDoS attacks and DNS security. His approach is usually based on measurements.

Currently he is "Beirat" of the  CODE Cybersecurity research institute in München and member of the SURF Scientific Technical Council (WTR). He has chaired the IFIP Technical Committee on "Communications Systems" (IFIP-TC6, 2013-2017), as well as the EU Future Internet cluster (2012-2014). He has been coordinator of the European Network of Excellence on "Management of the Future Internet" (FLAMINGO, 2012-2017). 

He has participated in many European and Dutch research projects, as member, evaluator and as reviewer. He has contributed to research and standardization activities as a founding member of the Internet Research Task Force (IRTF) Network Management Research Group (NMRG) and as RFC author. He has been editor of the IEEE Communications Magazine series on "Network & Service Management", associate editor of the International Journal of Network Management (IJNM), and Editorial Advisory Board member for the Journal of Network and Systems Management (JNSM). He is Steering Committee member of the IFIP/IEEE NOMS and IM Symposia (NISC), CNSM, IFIP Networking as well as TMA.

Research

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