After carrying out the state of the art analysis conforming this position, this phenomenon is further discussed. However, one of the major conclusions derived by the authors is that a secure heterogeneous environment is an achievable goal. Existing services suffer from the problem of not having a common definition on how to communicate with and trust each other, as well as how to choose the right service for a specific requirement or action. To address this gap, the paper will focus on specifying the requirements for common, standardised interfaces for specific layers. These requirements are intended to be used for supporting the development of a more secure, diverse system landscape. The paper then continues with discussing potential use cases for the requirements and then presents still open challenges that need a scientific solution. The major conclusions drawn from the state of the art analysis are again summarized in the final chapter of this paper.
