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.

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.
