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.
The AWS Network Policy Agent is a Kubernetes node agent that enforces network policies on Amazon EKS clusters. It implements fine-grained pod-level network security using eBPF (extended Berkeley Packet Filter) programs that are loaded into the Linux kernel to control ingress and egress traffic at the network interface level.
The agent compiles and loads eBPF TC (Traffic Control) programs that intercept and filter packets based on Kubernetes NetworkPolicy resources. It supports both IPv4 and IPv6 policies and uses CO-RE (Compile Once – Run Everywhere) technology to ensure the eBPF programs work across different kernel versions without recompilation.
The agent runs as a DaemonSet on each EKS node alongside the AWS VPC CNI plugin. It watches for NetworkPolicy objects via the Kubernetes API and translates them into eBPF maps and programs that enforce the desired connectivity rules between pods.
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.
These images are published with near-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.
