Information

The macOS system must disable Trivial File Transfer Protocol (TFTP) service.

GROUP ID: V-277108
RULE ID: SV-277108r1149417

If the system does not require TFTP support, it is nonessential and must be disabled.

The information system must be configured to provide only essential capabilities. Disabling TFTP helps prevent the unauthorized connection of devices and unauthorized transfer of information.

Note: TFTP service is disabled at startup by default.

Solution

Configure the macOS system to disable TFTP service with the following commands:

/bin/launchctl bootout system/com.apple.tftpd
/bin/launchctl disable system/com.apple.tftpd

The system may need a restart for the update to take effect.
