Closing remarks for my third and final CiliumCon as co-chair. A little bittersweet, but one of the things I love about open source is giving other people the opportunity to grow. I'll be in Amsterdam but not as co-chair 🥲

Liz Rice, Joe Stringer, and I lead a discussion on what projects should think about when trying to write an effective AI policy. Slides are lights on details, but be sure to catch the full recording with all the conversations when it comes out

Boundaries in infrastructure are where we can segment and secure. But where we find boundaries has drastically changed. Firewalls lived at the edge, then microsegmentation brought them into the DC, and now with eBPF, we’re watching them move into the workloads
The Network Segmentation Spectrum
Cyber attacks show how quickly intruders can move laterally when segmentation is weak. The old perimeter firewall model is no longer enough. Segmentation now exists across a spectrum: macro controls that...

Using XDP for Egress Traffic
XDP only works for ingress. We found a loophole that lets it work for egress. Here's how we did the impossible.
