SV-96429r1_rule The macOS system must have unused network devices disabled.

Vulnerability discussion

If an unused network device is left enabled, a user might be able to activate it at a later time. Unused network devices should be disabled.

Check content

To list the network devices that are enabled on the system, run the following command: /usr/bin/sudo /usr/sbin/networksetup -listallnetworkservices A disabled device will have an asterisk in front of its name. If any listed device that is not in use is missing this asterisk, this is a finding.

Fix text

To disable a network device, run the following command, substituting the name of the device in place of "''": /usr/bin/sudo /usr/sbin/networksetup -setnetworkserviceenabled '' off

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.
