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
