Abstract

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. Safety-critical 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.
