Why permit params in controllers are protected in rails

Question

I see two difference experience in rails. In multiple projects permit_params are defined in protected and in multiple projects they are defined in private

What is the difference between these two strategies?

Please explain briefly

I think when we create an gem or plugin where we will allowed user to inherit controller in this case we should use protected other wise should be private — Thorin, May 26 '16 at 06:35

private

The type or member can only be accessed by code in the same class.

protected

The type or member can only be accessed by code in the same class or struct, or in a derived class.

An example of a private method: http://matthodan.com/2010/08/08/ruby-private-methods-vs-protected-methods.html
