About me

Steffen WendzelI am a professor of information security and computer networks at Worms University of Applied Sciences and also affiliated with Fraunhofer FKIE (Bonn) and Cleopa (near Berlin). I received my Ph.D. in 2013 from the University of Hagen. Aged 17, I started writing books (sold 60,000 printed+electronic copies so far and counted 50,000 free downloads of my older editions). A list of my 120+ publications can be found here. My publications appeared in high-quality journals/conference such as ACM CSUR, CACM, Wiley SCN, IEEE Security & Privacy, IEEE LCN, IFIP SEC, Springer ANTE and J.UCS. However, I also wrote books on the Linux operating system and contributed tons open source code/patches to the free software community. There is also a list of selected talks.

My research focuses on network information hiding (network covert channels and network steganography), science of security (SoC), IoT/smart buildings/homes, security of embedded communication protocols, and information security terminology/taxonomy.

Some of my key publications are on the fundamentals (SoC) of network information hiding: taxonomy/patterns/fundamentals [1,2], creativity evaluation of research paper submissions [3] and scientific methodology of information hiding [4]. Some of my other key contributions are focusing on traffic normalization and active wardens [5, 6] and covert channel optimization [7,8].

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 information security, I am interested in university history, campus novels, and retro computing – in particular: operating system history and historic network protocols. I own a small collection of rather historic books on these retro computing topics. Since about five years, I am also a mid-distance runner (5km to half-marathon).
