For upcoming smart grid information and communication architectures, security is an indispensable requirement in order to ensure security of supply, to prevent damages to the electricity supply, loss or manipulation of personal or accounting information, etc. This must be taken into account throughout all developmental phases when creating such a framework, i.e., from the design phase on. Therefore, a Security-by-Design (SbD) approach has to be used which is able to address all potential harms to the envisioned system. Especially through the integration of distributed energy resources, new stakeholders (who may have low awareness of potential security risks) have to be considered, e.g., private households with photovoltaic/battery systems. Through the usage of the Internet for the exchange of sensitive data, intrusions from malicious attackers are facilitated. To cope with this, distributed energy resources have to include a comprehensive security subsystem. In this paper, an exemplary solution for the consideration of these issues in highly distributed infrastructures is given.
