You can use the location directive in web.config.

<location path="resources">
    <system.web>
            <authorization>
                    <allow roles="Customers"/>
                    <deny users="*"/>
            </authorization>
    </system.web>
</location>

This way you can put your resources (pdf, images) in the directory "resources". Only Customers will be able to show them. Note that they can still download the files and upload it to other server, but I guess you already know that.
