Difference between RBAC and trusted image

Hi,

I came across this question. However, I wonder if we can ensure images are secure by configuring Role Based Access Control? I guess RBAC also allows use to restrict access to Docker Trusted Registry, isn’t it?

Thanks

Role-based access control (RBAC) is a method for controlling system access based on roles assigned to users within an organization. RBAC is defined around predefined roles and the privileges associated with those roles (also known as role bindings). Roles are a collection of permissions that you can bind to a resource; this binding allows the privileges associated with that role to be performed on that resource. You must grant the role to a principal at the time you bind a resource to the role.
