Why is Binary Authorization useful?

Binary Authorization is a critical security feature for managing the deployment of container images in Google Cloud. Its usefulness lies in its ability to enforce stringent deployment policies by incorporating several key functions that address various aspects of security and compliance.

One primary benefit is the ability to ensure that images have passed necessary security and quality tests, which includes conducting vulnerability scans to identify known issues or risks before they are deployed. This creates a safeguard against potential exploits and vulnerabilities that could compromise applications or services.

Furthermore, Binary Authorization allows for the deployment of only those images that are explicitly approved. This means that organizations can maintain a whitelist of trusted images, effectively limiting the risk associated with deploying unverified or malicious third-party images.

Additionally, Binary Authorization facilitates verification that images are built and signed by trusted Continuous Integration/Continuous Deployment (CI/CD) pipelines. This ensures that the integrity of the build process is maintained and that only validated and secure images make it to production environments.

In summary, Binary Authorization is beneficial because it consolidates multiple layers of security—ensuring images meet quality standards, controlling the deployment of third-party images, and verifying the sources of images through trusted build processes.
