If you are an end user you would get an error that the you have stumbled upon a restricted content (this is different from the restricted space error).
As from the side of the space admin, you can see which pages are restricted in Space settings > Content > Restricted.
When you have the access to a restricted page, you would see a red lock on the right side of the screen that indicates that the page has been restricted for certain users.
