The real fix isn't scanning at the end of the pipeline; it's changing the ingredients. Software supply chain security requires three pillars working together: provenance (who built it and how), attestation (cryptographic signing), and introspection via a full SBOM. SLSA Level 3 compliance provides cryptographic proof that an image was built from a known commit and hasn't been tampered with. For platform enforcement, Kubewarden — a CNCF sandbox admission controller — can block unsigned or untrusted images from reaching production. Switching from `node:latest` to a SUSE-maintained trusted base image dropped 1,004 CVEs to zero with a single line change. ## Full article daily.dev links to this article rather than hosting it.
