Vasileios Giotsas
Vasileios (Vasilis) Giotsas is a research engineer focusing on network measurements and telemetry, the risk assessment and mitigation of topological and macroscopic vulnerabilities of critical Internet infrastructures, and the analysis of Internet routing policies and performance. He has contributed in multiple mission-critical research projects funded by the UK National Cyber Security Center (NCSC), and the US Department of Homeland Security (DHS).
Session
I'm a research engineer working at Cloudflare and in my work we need to measure various aspects of the Internet, such as the Internet topology (how ISPs are interconnected), performance of end-to-end paths, and security risks of the routing system. To collect such measurements, we rely on various open-source python tools that are less known but enable large-scale measurements of real-time Internet phenomena. In this talk I will first introduce briefly some core Internet networking aspects, why engineers and researchers want to measure and monitor them and then I will walk you through a suite of open-source Python tools we use in Cloudflare to probe, map and analyze macroscopic properties of the Internet ecosystem. My aim is for attendees to walk away with some fundamentals on networking and concrete, reusable examples on how to build their own Python-powered Internet measurement pipelines.
