The container platform registry must employ a deny-all, permit-by-exception (whitelist) policy to allow only authorized container images in the container platform.
Description
Controlling the sources where container images can be pulled from allows the organization to define what software can be run within the container platform. Allowing any container image to be introduced and instantiated within the container platform may introduce malicious code and vulnerabilities to the platform and the hosting system. The container platform registry must deny all container images except for those signed by organizational-approved sources.
