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

Check Text (C-277108r1149417_chk)

Verify the macOS system is configured to disable TFTP service with the following command: result="FAIL" enabled=$(/bin/launchctl print-disabled system | /usr/bin/grep '"com.apple.tftpd" => enabled') running=$(/bin/launchctl print system/com.apple.tftpd 2>/dev/null) if [[ -z "$running" ]] && [[ -z "$enabled" ]]; then result="PASS" elif [[ -n "$running" ]]; then result=result+" RUNNING" elif [[ -n "$enabled" ]]; then result=result+" ENABLED" fi echo $result If the result is not "PASS", this is a finding.

Fix Text (F-81168r1149380_fix)

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.
