Short Bio

Marko Jahnke is a senior information and cyber security specialist with experiences as research scientist, system architect, analyst, consultant, and project manager since 1999. Currently, Dr. Jahnke is a senior InfoSec engineer with a German federal agency.

Prior to this position, he worked for multiple German federal agencies in the cyber security domain as senior officer, analyst, and CERT/CSIRT (Computer Security Incident Response Team) manager. Earlier, he served as team leader and deputy head of the cyber defense research group of the Fraunhofer Research Institute for Communication, Information Processing, and Ergonomics (FKIE).

He is author and co-author of more than 35 scientific publications. He holds a Diploma (MSc) and a PhD degree in computer science, both from the University of Bonn, Germany.

His current focus is on operational real-time security monitoring and attack detection in high-speed networks.
