SV-90819r1_rule The OS X system must be configured with iTunes Music Sharing disabled.

Vulnerability discussion

When iTunes Music 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. Unnecessary network services should always be disabled because they increase the attack surface of the system. Disabling iTunes Music Sharing mitigates this risk.

Check content

To check if iTunes Music Sharing is disabled, run the following command: /usr/sbin/system_profiler SPConfigurationProfileDataType | /usr/bin/grep disableSharedMusic If "disableSharedMusic" is not set to "1", this is a finding.

Fix text

This setting is enforced using the "Custom Policy" configuration profile.

Pro Tips

Lavender hyperlinks in small type off to the right (of CSS class id, if you view the page source) point to globally unique URIs for each document and item. Copy the link location and paste anywhere you need to talk unambiguously about these things.

You can obtain data about documents and items in other formats. Simply provide an HTTP header Accept: text/turtle or Accept: application/rdf+xml.
