The Internet Measurement and Network Security activity focuses on exploiting network measurements to understand and answer fundamental questions about the Internet. Some of the questions we are currently working on are the following:

• To what extent is the IPv4 address space utilized?
• How effective is Internet scanning at recruiting new botnet members?
• What are the characteristics of the Background Radiation of the Internet (a persistent noisy component of Internet traffic that results from scanning and misconfigurations) in production networks and how it has evolved over time?
• How geopolitical factors have shaped the expansion of the Internet within different countries and at a global level?

We collaborate with several other research groups such as the groups of Dr. Claffy in the Collaborative Association for Internet Data Analysis (CAIDA) of the University of California San Diego (UCSD), Prof. Plattner in ETH Zurich, and Prof. Weidmann in the Political Sciences Department of the University of Konstanz.

Activity Leaders: Prof. Xenofontas Dimitropoulos
