In the web.config there is a section below <system.web> where you can add:

<authorization>
    <deny users="?" />
</authorization>

It is normal that you put pages that requires login in a certain sub-directory and thus you can put a new web.config in that folder with the above lines inside <system.web>, this will prevent unauthorized access.

MSDN has a great section about Forms Authentication that I recommend you to read.
