Cyber-Physical Systems (CPS) distributed over a large territory, require secure communication not only among various parts of system, but also with operation center. Building its own communication networks by the system operator is financially demanding, which is why more or less open communication systems are used. This is connected with higher requirements for the security of applications, operated in a CPS. European project COSMOS has been creating a tool that applies DevOps development technologies from the IT field to the field of embedded systems. On the example of requirements on railway operation system, we show that for use this very complex software must be adapted to real requirements on railway operation system. The article shows results of tests parts of complex software created in the COSMOS project for Czech railway operation system.

Keywords: Cyber-physical systems, Risks, Security, Risk-based design, Software, Integral safety, Railway.
