About me


Steffen WendzelI am a professor of information security and computer networks at Worms University of Applied Sciences (also part of the Centre for Technology Transfer and Telecommunications) and also affiliated with Fraunhofer FKIE (Bonn) and Cleopa (near Berlin). I received my PhD in 2013 from the University of Hagen. Aged 17, I started writing books (sold ~60,000 printed+electronic copies so far and counted 30,000 free downloads of my older editions). A list of my ~100 publications can be found here. There is also a list of selected talks.

My research primarily involves network information hiding (network covert channels and network steganography). However, I also work on building automation/smart building security, human aspects of information security, and information security terminology / taxonomy.

Some of my key publications are on information hiding taxonomy/patterns [1], creativity evaluation in infosec [2], information hiding methodology [3], traffic normalization/wardens [4, 5] and covert channel optimization [6, 7].

I am a member of several steering committees, initiatives, program and organizing committees (cf. details). I am (or was) lecturing and supervising at Augsburg University of Applied Sciences, Bonn University and Hagen University. A list of my projects, both funded and spare-time software projects, is also available.

In addition to computer science, I am interested in university history, campus novels and long-distance running.
