Build Level 3
Tamper-evident proof of how and from what sources this image was built. Build Level 3 is the highest the SLSA build track defines.
CycloneDX SBOM + SPDX SBOM
A software bill of materials in both CycloneDX and SPDX formats so it drops straight into your existing tooling. Audit exactly what you're shipping.
A Vulnerability Exploitability exchange document, Docker's assessment of which CVEs actually affect this image and which don't apply, so you can focus on real risk instead of chasing false positives.
Available
A link to everything used to build the image, package source code, Git repos, and build files, so you can audit or reproduce the build and stay compliant with open source licenses.
Every known vulnerability in this image, shown in full rather than hidden. The VEX data flags which ones actually apply, so you can tell real exposure from noise before you ship.
Exactly what changed in this build, down to the package bumps and fixes behind the version you're pulling.
Verifies no keys, tokens, or credentials were accidentally baked into the image.
The image layers were scanned for known malware signatures before publishing.
About Notation
Notation is a CLI tool for developers and operators that provides a standard way to sign and verify OCI artifacts. Its main purpose is to secure container images and related artifacts in registries and CI/CD pipelines. It supports artifact signing, signature verification, trust policy enforcement, and integration with pluggable key managers such as AWS KMS and Azure Key Vault. Notation uses the OCI Referrers API to store and discover signatures in OCI-compliant registries.
The tool can secure a wide range of artifacts, from container images to Helm charts and SBOMs, making it useful for both small projects and enterprise supply chains. Notation excels at ensuring only trusted, signed artifacts are deployed, reducing the risk of tampering and enabling compliance in Kubernetes and automated workflows.
About Docker Hardened Images
Docker Hardened Images are built to meet the highest security and compliance standards. They provide a trusted foundation for containerized workloads by incorporating security best practices from the start.
Why use Docker Hardened Images?
These images are published with zero-known CVEs, include signed provenance, and come with a complete Software Bill of Materials (SBOM) and VEX metadata. They're designed to secure your software supply chain while fitting seamlessly into existing Docker workflows.
