short bio

Olaf M. Maennel

The Internet has revolutionized the way in which we communicate, do business, or learn. Knowledge is now easier to access than ever, and what fascinates my research is the technology that enables this worldwide paradigm change.

Since July 2014 I am a full Professor for Cyber-Security at the Centre of Digital Forensics and Cyber Security at Tallinn University of Technology in Estonia. I got tenure in 2017. Before that i was with Loughborough University in UK and with the University of Adelaide in Australia. I have been general co-chair of ACM SIGCOMM 2015, ACM IMC 2017, and Global Internet Symposium GI'17. I serve as EU expert evaluator and vice-chair for Horizon H2020 calls.

My interests are in security, focusing on:

  • network security & network forensics
  • network measurements (active & passive)
  • WAN-routing & security (IPv6, BGP/BGPsec,...)
  • communication protocol security including, but not limited to the public transport sector

I obtained my Ph.D. (Dr. rer. nat.) in computer science from the Technical University of Munich, Germany, in the group of Prof Anja Feldmann, PhD in 2005 and my Diploma (MSc) from the Saarland University, Saarbrücken, Germany in 2002.

Cyber Security Research

The term Cybersecurity has become a buzzword in the recent years. It's overloaded and doesn't mean much anymore. Many people, including me, try to avoid the word as much as possible. In a university context, however, it's a student magnet. We see a very high demand in 'cybersecurity education', but it should be clearly understood that 'cybersecurity' is not a scientific discipline in itself. Instead it combines insights from many other disciplines: for example, from computer science it takes secure software design, or how to build intrusion detection systems, methods for vulnerability testing, and so on; cryptography is rooted in mathematics; psychology helps to understand human factors; aspects of forensic science are used by law enforcement agencies; social sciences, business and economic understanding is essential; operational and strategic risk management models & audits help with reducing the threats in day-to-day operations; and of course legal and political disciplines are required.

For me the term 'cybersecurity' is simply an expression meaning interdisciplinary. In fact interdisciplinarity and effective communication are the only way we can fight today's problems in 'cyberspace'. It is the combination of knowledge and insights from several great areas of science that is required to secure 'cyberspace'. This is exiting, interesting, but also very challenging.


With respect to my teaching, cyber security is a very interesting area as well. If we consider the interdisciplinary scope of cybersecurity, we must also realize that this provides great challenges for teaching. Traditional teaching does not work anymore. We need to rethink our methods/values and implement innovative teaching into our programs. I have also recently been involved in the restructuring of Loughborough's postgraduate Internet Computing and Network Security (ICNS) program and contribute to the constant development of Tallinn University of Technology's Cyber Security MSc.

For more information about my view on teaching cyber security in higher-education, please see my teaching statement.

Since April 2012 I am a Fellow of the UK Higher Education Academy (HEA) having completed the HEA accredited "New Lecturers' Course", which is a comprehensive course for new academic faculty in UK.
