By restricting the transfer users to a limited part of the server's file system, this prevents unauthorized data transfers. By default, all system users can establish a FASP connection and are only restricted by file permissions.
Verify the Aspera High-Speed Transfer Server restricts Aspera transfer users to a limited part of the server's file system. Check that each user is restricted to a specific transfer folder with the following command: Warning: If an invalid user/group name is entered, the asuserdata command will return results that may appear accurate. Ensure that the user/group name is valid and entered into the command correctly. $ sudo /opt/aspera/bin/asuserdata -u <username> | grep absolute canonical_absolute: "<specifictranferfolder>" absolute: "<sepcifictransferfolder>" If the transfer user's docroot is set to "<Empty String>" or is blank, this is a finding.
Configure the Aspera High-Speed Transfer Server to restrict Aspera transfer users to a limited part of the server's file system with the following command: $ sudo /opt/aspera/bin/asconfigurator -x "set_user_data; user_name, <username>;canonical_absolute,<transferfolder>; absolute,<transferfolder>" Restart the IBM Aspera Node service to activate the changes. $ sudo systemctl restart asperanoded.service
