eBPF and Falco, with Leonardo Di Donato

Feb 18, 2020

We dive into the Linux kernel this week with guest Leonardo Di Donato, Open Source engineer at Sysdig. Leonardo works full-time on the Falco project, a runtime security engine that listens to the Linux kernel using eBPF - the extended Berkeley Packet Filter. Leonardo tells the hosts about the architecture of eBPF, how he has used it before and now, and what’s coming up for Falco.
