  To support maintenance and servicing of industrial machines, service
processes are even today often performed manually and analogously, although
supportive technologies such as augmented reality, virtual reality and digital
platforms already exist. In many cases, neither technicians on-site nor remote
experts have all the essential information and options for suitable actions
available. Existing service products and platforms do not cover all the
required functions in practice in order to map end-to-end processes. PLASMA is
a concept for a Cloud-based remote maintenance platform designed to meet these
demands. But for a real-life implementation of PLASMA, security measures are
essential as we show in this paper.
