Description
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. Satisfies: SRG-OS-000074-GPOS-00042,SRG-OS-000080-GPOS-00048

Who does this work

17 NICE work roles and 9 EC-Council certifications.

This is an inference across published mappings, not a single claim by anyone. This check maps to a control, which maps to a Cybersecurity Framework outcome, which NIST assigns to the work roles below. EC-Council separately maps its certifications to those same roles.

A certification prepares someone for a role. It is not evidence that a holder is qualified, and neither NIST nor EC-Council has stated that any certification here addresses this check.

Work-role assignments published by NIST (NICE Framework Components 2.2.0 and the CSF 2.0 OLIR crosswalk). Certification mappings published by EC-Council.

Details

Check Text (C-259499r987796_chk)

Verify the macOS system is configured to disable trivial file transfer protocol service with the following command: /bin/launchctl print-disabled system | /usr/bin/grep -c '"com.apple.tftpd" => disabled' If the result is not "1", this is a finding.

Fix Text (F-63146r941118_fix)

Configure the macOS system to disable trivial file transfer protocol service with the following command: /bin/launchctl disable system/com.apple.tftpd The system may need to be restarted for the update to take effect.
