New White Paper "IT/OT Security for the Internet of Railway Things

Germany, Darmstadt | December 06, 2020

Today, sensors are an integral part of railroad applications. They continuously collect data to optimize traffic, passenger flow management, energy and maintenance efficiency. On the one hand, this supports the high availability and safety aspect; on the other hand, the possible analyses effectively promote the increase of traffic performance. However, the widespread use of sensors and their networking as Internet of Railway Things (IoRT) also evoke new attack vectors, which must be countered efficiently and in compliance with the standards, laws and rules in railroad traffic.

The white paper "IT/OT Security in Internet of Railway Things (IoRT)" explains applications of IoRT devices and possible IT security strategies that simultaneously keep in mind the use of data, the operation of the devices and the adaptability to IT security requirements. The basis of these strategies is the application of the HASELNUSS architecture. The white paper was developed within the framework of the Cybersecurity Working Group (AG CYSIS), an innovation alliance of TU Darmstadt and DB Netz AG. The white paper was developed together with the cooperation partners Fraunhofer SIT, CISCO, ÖBB and INCYDE.

Invited Talk and Paper at 4th International Workshop on MILS: Architecture and Assurance for Secure Systems (MILS-18)

Luxembourg | June 25, 2018

co-located with IEEE/IFIP International Conference on Dependable Systems and Networks DSN2018 (, 25-28.06.18

Christian Schlehuber, DB Netz AG, was invited to present security challenges faced by future railways and emerging security concepts required for their efficient, reliable and safe operation.

Maria Zhdanova, Fraunhofer SIT, presented the paper “A Reference Architecture for Integrating Safety and Security Applications on Railway Command and Control Systems” produced in a collaborative effort by the members of the project consortium H. Birkholz, C. Krauß, M. Zhdanova, D. Kuzhiyelil, T. Arul, M. Heinrich, S. Katzenbeisser, N. Suri, T. Vateva-Gurova, and C. Schlehuber. The paper introduces the Haselnuss Reference Architecture for IT-based railway command and control systems that allows uncertified security functions to safely reside on the same hardware platform as (SIL) certified safety functions using the MILS approach. The audience included railway service and solution providers, security engineers, and security and dependability researchers from different countries.

Cybersecurity for the railway of tomorrow

The new research project "Hardware-based security platform for railway control and command systems" – HASELNUSS for short – is developing a security system that protects against attacks and takes into account the long lifecycles of the railway infrastructure. The first practical evaluation of this novel solution will be carried out in the test center of DB Netz AG and in the railway operating field Darmstadt.
