Verify the Aspera High-Speed Transfer Server set the default docroot to an empty folder. Check that the default docroot points to an empty folder with the following command: $ sudo /opt/aspera/bin/asuserdata -a | grep absolute canonical_absolute: "" absolute: "" If the default docroot is set to "", this is a finding. Review the default docroot file path from the previous command to ensure it is empty. $ sudo find -maxdepth 0 -empty -exec echo {} is empty. \; is empty. If the command does not return " is empty.", this is a finding.
