Description
The container platform must be capable of validating container images are signed and that the digital signature is from a recognized and approved source approved by the organization. Allowing any container image to be introduced into the registry and instantiated into a container can allow for services to be introduced that are not trusted and may contain malicious code, which introduces unwanted services. These unwanted services can cause harm and security risks to the hosting server, the container platform, other services running within the container platform, and the overall organization.
