As applications become more distributed, traditional monitoring and security tools are failing to keep pace. This article explores how eBPF, when utilized by the graduated CNCF Cilium and its sub-project Tetragon, combined with Software Bills of Materials (SBOMs), can provide insights and a security feedback loop for modern systems. We’ll create a container image and its SBOM. We’ll then launch it, simulate a breach, and see how our eBPF-based setup with Tetragon captures the issue. This will show how the SBOM can be used to debug and understand the incident.
