SV-38528r1_rule The Software Update Server URL must be assigned to an organizational value.

Vulnerability discussion

A computer can look for software updates on an internal software update server (SUS). Using an internal software update server reduces the amount of data transferred outside of the network. The organization can control which updates can be installed on a computer.

Check content

Open a terminal session and enter the following command. defaults read com.apple.SoftwareUpdate CatalogURL The value returned is the current Software Update Server. Verify it is an approved SUS. If no value is returned, the system is using a default Apple Update Server and this is a finding. NOTE: If the system is not using an authorized DoD SUS server, it should point to a null address.

Fix text

Open a terminal session and enter the following command. defaults write com.apple.SoftwareUpdate CatalogURL 'new_SUS_URL' (Where 'new_SUS_URL' is the URL or the address of the appropriate government SUS to be used.)

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.
