One option would be to add protected_attributes as a dependency for Katello but I'd probably recommend against it. We use strong_params pretty much everywhere--except when extending the foreman models. We call attr_accessible in about 8 places that I think we can switch over to parameter_filter. I am going to investigate that route.
