[TYPO3] Show pages to BE users only?

[Julian [JRK Software]]

Hello list,
I'm trying to figure out how to set some of the pages/menu items so they 
are visible if there is a BE user logged in.

For example, i have a page which outputs some custom plugins where a BE 
user can create FE users, edit their details, edit content with admPanel 
icons, etc. The idea is that all daily administration tasks will be 
performed in the front end. That is, this BE user will be not required 
to login into the back end.

Now, i need to find out how to show these pages to BE users only. They 
should be invisible to all FE users.

Any tips will be highly appreciated :))

Best regards,
Julian
