Discussion

Media sharing _MUST_ be disabled.

When Media Sharing is enabled, the computer starts a network listening service that shares the contents of the user's music collection with other users in the same subnet.

The information system _MUST_ be configured to provide only essential capabilities. Disabling Media Sharing helps prevent the unauthorized connection of devices and the unauthorized transfer of information. Disabling Media Sharing mitigates this risk.
