Ever wondered what’s behind that language on “technology transfer” in research proposals? Well, that’s one of our key activities at SIDN Labs. We’re a research team that aims to increase the operational security and resilience of the Internet infrastructure by bridging the worlds of academia and operations, specifically in the space of large-scale Internet measurements and technology development. We very often work with academic institutions (e.g., the University of Twente, the University of Southern California, and Delft University of Technology) and other research labs (e.g., NLnet Labs) and we use the results of these joint cybersecurity projects to further improve the services of SIDN, the not-for-profit operator of the Netherlands’ national top-level domain on the Internet, .nl. We also publish these results so that everyone in the Internet community can use them as well. In this talk, I’ll discuss a few example research projects and how we used their output for SIDN’s services.

It aims to enable an ongoing dialogue between experts from industry and academia and the general public (citizens, families, small and large businesses, public organizations, etc.). All of us are concerned.

How the digital transformation is changing our lives

The COVID-19 pandemic has shown all of us the benefits of information technology. It allows us to work at a distance, to live at a distance, and most importantly, to keep in touch at a distance – with younger and older people, those closest to us, and even make new contacts.

Our society relies more and more on information and operational technologies. Examples include water, energy, heat and cooling supply, communications, healthcare, production and processing of goods, transportation, national security, banking, research and education, and food production.

What all these areas have in common is that they make intensive use of networked distributed computer systems. These systems can be attacked in many ways. This is no longer just a problem for computer “pros” because computer systems are essential to all of us. The effects of “cyber-attacks” range from power outages to the collapse of the health care or banking sectors.
