What is Binary Authorization?
Binary Authorization is a deployment security service from Google Cloud that enforces policy-based controls for container images. The service prevents unauthorized or unsigned containers from being deployed to GKE, Cloud Run, or Anthos.
Core Features
- Attestation-based deployment control with cryptographic signatures
- Integration with Container Registry and Artifact Registry
- Flexible policy definition at project, cluster, or namespace level
- Dry-run mode support for testing policies
- Audit logging of all deployment decisions
Typical Use Cases
Secure CI/CD Pipelines: Only container images that have passed all build and test phases receive attestation and can be deployed.
Compliance Requirements: Organizations in regulated industries can prove that only verified software runs in production.
Multi-Team Governance: Central security teams define policies that apply to all development teams.
