Description
The container platform registry is used to store images and is the keeper of truth for trusted images within the platform. To guarantee the images integrity, access to the registry must be limited to those individuals who need to perform tasks to the images such as the update, creation, or deletion of images. Without this control access, images can be deleted that are in use by the container platform causing a denial of service (DoS), and images can be modified or introduced without going through the testing and validation process allowing for the intentional or unintentional introduction of containers with flaws and vulnerabilities.
