Develop custom organization policies that restrict GKE cluster deployments to container images hosted within a specific Artifact Registry project where your approved images reside.

Enforce Binary Authorization in your GKE clusters. Integrate container image vulnerability scanning into the CI/CD pipeline and require vulnerability scan results to be used for Binary Authorization policy decisions.

Automatically deploy new container images upon successful CI/CD builds by using Cloud Build triggers. Set up firewall rules to limit and control access to instances to mitigate malware injection.

Build a system using third-party vulnerability databases and custom scripts to identify potential Common Vulnerabilities and Exposures (CVEs) in your container images. Prevent image deployment if the CVE impact score is beyond a specified threshold.
