Topology and Orchestration Specification for Cloud Applications (TOSCA) language provides such standard by employing semantics for rep- resentation of components and business processes of a cloud application. Advancements in the fields of Cloud Computing and Internet of Things (IoT) has opened new research areas to support 4th industrial revolution (Industry 4.0), which in turn has resulted in the emergence of smart services. One application of smart services is predictive maintenance, which enables the anticipation of future devices’ states by implementing functions, for example, analytics algorithms, and collecting huge amounts of data from sensors. Considering performance demands and runtime constraints, either the data can be shipped to the function site, called data shipping or the functionality is provi- sioned closely to the data site, called function shipping. However, since this data can contain confidential information, it has to be assured that access to the data is strictly controlled. Although TOSCA already enables defining policies in general, a concrete data security policy approach is missing.
