Security for Safety

Safety-critical systems are increasingly interconnected, be it through local networks or even through the Internet. This raises security concerns for both stakeholders and end users, since these traditionally closed systems now expose communication interfaces, making them vulnerable to all kinds of attacks that might be exploited even from remote locations over the Internet.

Fraunhofer IESE has teams of experts who focus on both security technology and safety engineering. We offer you a safety-security co-engineering service so that you can be assured that your safety-critical systems will be well protected from cyber-attacks. In addition, we can support you in setting up adequate safety and security engineering lifecycles at your company and underpin them with corresponding tooling for model-based engineering. The tooling can be based upon our safeTbox tool, which could also be tailored to your specific needs, such as specific methods or techniques, automation, or integration with other tools.

As an applied research institution, we have been investigating different approaches related to safety-security co-engineering in a range of national and European projects as well as in bilateral industry collaborations over the past years. These projects include the European projects CRYSTAL, DEIS, and SECREDAS as well as the national projects SPES, SPES XT and CREST. For several years, we have been organizing the “Safety meets Security" conference together with Hanser to bring together safety and security experts from different domains and enable an exchange of ideas about challenges, solutions, and standardization activities.

Selected Projects


Reference Project DEIS

Dependability Engineering Innovation for Cyber-Physical Systems

Development of a holistic approach for the safety assurance of cyber-physical systems at development time and at runtime. Key contributions of Fraunhofer IESE include the concept and the tool realization of “Digital Dependability Identities”, dependability-oriented Digital Twins of systems.

(Duration: 01/2017 - 12/2019)


Reference Project SECREDAS

Creation of trustworthy autonomous systems

Methods for the development of components for the creation of trustworthy autonomous systems.

(Duration: 05/2018 – 04/2021)


SPES_XT: Software Platform Embedded Systems “XT”

While the complexity of embedded systems is increasing rapidly, innovation cycles are becoming ever shorter. This trend can now also be observed increasingly in safety-relevant applications.
