Restricted Access to some pages?

Excuse my question but I am a newbie. In Perth Pro, is there a way to restrict some pages to sign in access (similar to the way we sign in to the forums)? I am working on a website with some pages RESTRICTED. Sure there is a simple solution, but cannot fnd it in the documentation. Maybe the answer is so simple that I am missing it.
