Configure Image Provenance for your deployment.
Kubernetes supports plugging in provenance rules to accept or reject the images in your deployments. You could configure such rules to ensure that only approved images are deployed in the cluster.
You need to regularly maintain your provenance configuration based on container image updates.
Review the pod definitions in your cluster and verify that image provenance is configured as appropriate.
Follow the Kubernetes documentation and setup image provenance.
By default, image provenance is not set.
