Title

The macOS system must disable Remote Apple Events.

Control

Verify the macOS system is configured to disable Remote Apple Events with the following command: /bin/launchctl print-disabled system | /usr/bin/grep -c '"com.apple.AEServer" => disabled' If the result is not "1", this is a finding.

Discussion

If the system does not require Remote Apple Events, support for Apple Remote Events is nonessential and must be disabled. The information system must be configured to provide only essential capabilities. Disabling Remote Apple Events helps prevent unauthorized connection of devices, transfer of information, and tunneling. Satisfies: SRG-OS-000080-GPOS-00048, SRG-OS-000096-GPOS-00050

Fix

Configure the macOS system to disable Remote Apple Events with the following commands: /usr/sbin/systemsetup -setremoteappleevents off /bin/launchctl disable system/com.apple.AEServer Note: Systemsetup with -setremoteappleevents flag will fail unless Full Disk Access to systemsetup or its parent process is granted. This requires supervision.
