Security as a Safety Issue in Rail Communications

Systems whose failure can lead to the damage of property or the environment, or loss of human life are regarded as safety-critical systems. It is no longer adequate to build safety-critical systems based on the control of errors and failures alone. Safetycritical systems must also deal with securing the data that is used in their operation. While safety and security engineering have evolved separately, there are a number of similarities. These similarities and efforts to integrate safety and security are identified. A project looking at securing safety-critical communications for the Australian rail network is also discussed.
