The macOS system must disable Trivial File Transfer Protocol service.
An XCCDF Rule
Description
<VulnDiscussion>If the system does not require Trivial File Transfer Protocol (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 the unauthorized transfer of information. Note: TFTP service is disabled at startup by default macOS.
