Binary Authorization is a Google Cloud service that provides deploy-time
enforcement of security policies for
Google Kubernetes Engine (GKE) and
Google Distributed Cloud. It supports container
images in Container Registry, Artifact Registry and other container image
registries.
At deploy time, Binary Authorization can use signatures called attestations to determine that a process was completed earlier.
For example, you can use Binary Authorization to:
Verify that a container image was built by a specific build system or
continuous integration (CI) pipeline.
Validate that a container image is compliant with vulnerability signing policy.
Verify that a container image passes criteria for promotion to the next
deployment environment, such as development to QA.
