  • certMILS eases Security Certification of Railway Systems

    In the latest issue of Global Railway Review, Dr. Sergey Tverdyshev (Director of Research & Technology at SYSGO) talks about security certifications of railway systems considering the MILS concept. He is the technical leader of the certMILS project – certMILS aims to protect critical infrastructure against cyber-attacks by compositional security certification to deliver a certified Multiple Independent Levels of Security (MILS) platform. But how can this be applied to railway systems?

  • A Modular Train Control System through the Use of certified COTS HW/SW and qualified Tools

    The European Rail Traffic Management System (ERTMS) forms the basis for standardization in relation to train control systems (ETCS), command control and safety technology, and Integrated Electronic Control Centres (IECC) in Europe [ETC16]. The previous HW/SW systems in these fields followed a monolithic integration approach applied by the individual manufacturers. This harbours problems relating to the compatibility of the systems of the various manufacturers, creates dependencies and reduces…
