Title

Disable Remote Apple Events

Control

/bin/launchctl print-disabled system | /usr/bin/grep -c '"com.apple.AEServer" => disabled'

Discussion

If the system does not require Remote Apple Events, support for Apple Remote Events is non-essential and _MUST_ be disabled.

The information system _MUST_ be configured to provide only essential capabilities. Disabling Remote Apple Events helps prevent the unauthorized connection of devices, the unauthorized transfer of information, and unauthorized tunneling.

Fix

[source,bash]
----
/usr/sbin/systemsetup -setremoteappleevents off
/bin/launchctl disable system/com.apple.AEServer
----
NOTE: Systemsetup with -setremoteappleevents flag will fail unless you grant Full Disk Access to systemsetup or its parent process. Requires supervision.
