  As part of the Internet of Things (IoT) and Industry 4.0 Cloud services are
increasingly interacting with low-performance devices that are used in
automation. This results in security issues that will be presented in this
paper. Particular attention is paid to so-called critical infrastructures. The
authors intend to work on the addressed security challenges as part of a funded
research project, using electrical actuators and battery storages as specific
applications. The core ideas of this research project are also presented in
this paper.
