Our society is heavily dependant on mobility. We have developed various means of transport, that nowadays increasingly utilize networked devices that solve tasks collaboratively or distributively. Sensors and actuators are deployed in the infrastructure to support monitoring, operation and maintenance, what makes them part of the Internet of Things. Car-to-car communication tries to optimize traffic flow. Environment sensors determine the condition of bridges to support a better maintenance strategy. Transportation is a critical infrastructure that requires measures against a variety of failures and threats in order to maintain an adequate level of supply. Defending critical infrastructures against cyber-attacks is the responsibility of information security. The Security Engineering Group is involved in several projects that improve the security of transportation infrastructures.
The CYSIS workgroup was established by Deutsche Bahn AG and TU Darmstadt within the framework of the Innovation Alliance and the existing DB RailLab on 25 January 2016. The purpose of the workgroup is to make effective challenges to the cybersecurity of safety-critical infrastructure intensified by digitisation in the railway industry possible.
The Cybersecurity workgroup forms a basis for an intensive exchange of information between industry and academia in the railway sector, in order to benefit from each other's knowledge. Effective defence mechanisms and countermeasures can be researched and developed further with the assistance of partners from academia, including CYSEC, the Department of Cybersecurity at TU Darmstadt. The desired outcome is the networking of the railway industry with academic research on cybersecurity.
The workgroup is meeting regularly in the following subgroups:
In recent years, the majority of the world's Critical Infrastructures CIs evolved to become more flexible, cost efficient and able to offer better services and conditions for business opportunities. Towards this evolution, CIs and companies offering CI services had to adopt many of the recent advances of the Information and Communication Technologies (ICT) field. This adaptation however, was rather hasty and without thorough evaluation of its impact on security. The result was to leave CIs vulnerable to a whole new set of threats and attacks that impose high levels of risk to the public safety, economy and welfare of the population. In so far, the main approach to protect CIs is to handle them as comprehensive entities and offer them a complete solution for their overall infrastructures and systems (IT&OT departments). However, complete CI protection solutions exist in the form of individual products from individual companies. These products integrate only in tools/solutions designed by the same company, thus offering limited technical solutions. The main aim of CIPSEC is to create a unified security framework that orchestrates state-of-the-art heterogeneous security products to offer high levels of protection in IT (information technology) and OT (operational technology) departments of CIs. As part of this framework CIPSEC will offer a complete security ecosystem of additional services that can support the proposed technical solutions to work reliably and at professional quality. These services include vulnerability tests and recommendations, key personnel training courses, public-private partnerships (PPPs) forensics analysis, standardization and protection against cascading effects. All solutions and services will be validated in three pilots performed in three different CI environments (transportation, health, environment). CIPSEC will also develop a marketing strategy for optimal positioning of its solutions in the CI security market.

Information Technology (IT) is increasingly utilized in railway systems to introduce new functions and improve process efficiency. Due to the digitalization of the railway infrastructure and the replacement of proprietary networking infrastructures with IP-based infrastructures the risks of cyberattacks increases and new IT security requirements appear. As the railway system is a critical infrastructure, that is strongly regulated by the German IT security act (IT-Sicherheitsgesetz), appropriate security solutions need to be developed. The aim of HASELNUSS is the development of a customized, hardware-based security platform for the railway command and control system that provides the required security functions without jeopardizing safety. The platform features provisions to ensure the system integrity and constitutes the foundation for secure infrastructure networking. It includes secure patch and update management, health monitoring, anomaly and attack detection as well as countermeasures against side-channel attacks. The developed security platform will be implemented in demonstrators during the project.
