Spicing up Container Image Security with SLSA and GUAC

Explore container image security enhancement techniques using SLSA (Supply chain Levels for Software Artifacts) and GUAC (Graph for Understanding Artifact Composition) in this informative conference talk. Learn how to add SLSA provenance metadata to container images and establish strong links between images and their source code across multiple build systems, including GitHub Actions and Google Cloud Build. Discover methods for verifying images and their metadata before deployment, both locally and in Kubernetes environments. Gain insights into using policy engines like Kyverno and Sigstore policy-controller to verify an image's source code repository, builder identity, and build entry points, enhancing protection against malicious images in production environments. Delve into the integration of SLSA with GUAC to gain a deeper understanding of image supply chains, including contents and build provenance from base layers upwards.
