Global Visibility into the Internet’s Security and Performance

Liz Izhikevich (Stanford University)

Tuesday, Apr 2, 2024

Internet security and performance problems often brew invisibly. Protecting and improving the Internet’s operations requires real-time visibility into networks and their users. However, the Internet's size, ephemerality, and diverse deployment patterns challenge visibility. In this talk, I will show how building data-collecting systems that rigorously account for the Internet's complexities reveal previously unseen critical operational challenges and threats. These include the discovery of billions of often-vulnerable IPv4 services and convoluted satellite routing patterns that take detours around the world.
