DSC Security II

•  LabVIEW DSC Periodic I/O Servers run as SYSTEM and create a Security Vulnerability

•  http://digital.ni.com/public.nsf/allkb/C351184309F8F8868625789900600E11?OpenDocument

•  ACC-LabVIEW-Interface uses Shared Variable Engine process owner for authentication

•  => Change account name of Shared Variable Engine service
