Can you please put in the lab instructions on how to change the default settings for not being able to expose any files to the internet?

By default, you can’t expose files to the public by the looks of things. Maybe something to address in the lab. I get this error when I try to expose a file to the public… "This object is public and can be accessed by anyone on the Internet. To remove public access, search for and remove all public entries from the object’s permissions."
