Courses: Advanced Networking and IoT Security

I coordinate and teach two M.Sc. courses at the University of Twente (UT): Security Services for the IoT (SSI) and Advanced Networking (ANET), both of which are collaborations with SIDN Labs. SSI is also part of the 4TU cybersecurity Master program.

ANET is a 1st quartile course (September through November), whereas SSI is part of the UT's 4th quartile teaching program (April through June).

If you're a student and intereseted in SSI or ANET, then please make sure to browse a few of the courses' papers before you sign up to verify that the course matches your interests, study plan, prerequisites, etc. You can sign up through the UT's course management system, OSIRIS. Hope to see you in class!

The ANET teaching team consists of Pieter-Tjerk de Boer (UT), Geert Heijenk (UT), Roland van Rijswijk-Deij (UT and NLnet Labs), and myself. The SSI teaching team conists of Elmer Lastdrager (SIDN Labs), Ramin Yazdani (UT), Etienne Khan (UT), and me.
