Superset software validation

[stannnman]

We are looking to deploy the Superset quickstart and notice the Superset container used seems to be owned by "untitled-registry" in the ECR public gallery.

Is this provided by AWS or a third party - and what level of validation has been performed to ensure the software is legitimate and not infected?

Many thanks for your help.
