Liz Rice - VP of open source engineering at Aqua Security

eBPF has been described as “Superpowers for Linux,” and recently we’ve seen an explosion of tools that use it to power observability, security and more. It's an exciting technology that enables running bespoke programs directly in the kernel. In this talk Liz uses live-coding examples to explore how eBPF programs are loaded and run in the kernel, and how user-space code can communicate with them to extract [...]
