Supply chain security is a topic that needs little introduction, but still goes many layers deep. My colleagues André Martins and Feroz Salam, did a great write up of the defense in depth strategy Cilium uses to secure its CI/CD pipeline. I love how it skips the theoretical and goes right into the implementation, like why we use two-phase checkouts for pull_request_target and the gaps that we are still trying to close.
My other favorite security write up from this week is how Cloudflare mitigated the “Copy Fail” Linux vulnerability with eBPF. Instead of waiting for a full kernel rollout, they used eBPF to surgically block the vulnerable code path at runtime. As I said last week, the future of runtime security is live patching and enforcement in the kernel. I need to go jump in a hot spring so let’s 🐝 -gin.
