Allow certain Users groups to view "secret" media?

Hi guys

first and foremost I apologize if i'm in the wrong section...

I'm using cutenews for my company's website and was wondering if there was some possible way to enable a specific set of users to view a specific set of media?

i.e. - we are a magazine company and our digital issues are uploaded online for users to view for free, but we want to require users to be at least logged in (maybe as a "subscribers" category or something) in order to view issues of the mag.

anybody know if this is possible and if so, the best way to go about doing it?

cheers
