STIG ID: APPL-15-002053  |  SRG: SRG-OS-000095-GPOS-00049 |  Severity: medium |  CCI: CCI-000381 |  Vulnerability Id: V-268507

Vulnerability Discussion

The System Settings pane for Siri must be hidden.

Hiding the System Settings pane prevents users from configuring Siri. Enabling any service increases the attack surface for an intruder. By disabling unnecessary services, the attack surface is minimized.

Check

Verify the macOS system is configured to disable the system settings pane for Siri with the following command:

/usr/bin/profiles show -output stdout-xml | /usr/bin/xmllint --xpath '//key[text()="DisabledSystemSettings"]/following-sibling::*[1]' - | /usr/bin/grep -c com.apple.Siri-Settings.extension

If the result is not "1", this is a finding.

Fix

Configure the macOS system to disable the system settings pane for Siri by installing the "com.apple.systempreferences" configuration profile.
