This paper presents a case study for identifying security-safety requirements by using safety analysis techniques. In order to construct distributed software-intensive safety-critical systems, it is crucial to identify not only the safety requirements, but also the security requirements simultaneously, due to the fact that security attacks on the communication channels could cause safety consequences, such as damage to properties or even loss of human lives. Security-safety requirements are proposed for addressing the requirement that describes the safety, security requirements and the influence of the security attacks on safety requirements. Although many safety and security analyses techniques are available for deriving the security-safety requirements separately, no effective approach exists that uses an identical model for identifying integrated security and safety requirements. In this paper, the procedures and lessons learned for deriving integrated security-safety requirements using one identical model that is established by safety analysis techniques are presented. The results from this case study show that the safety analysis techniques are applicable for determining integrated requirements for describing the behavior of an outdoor robot.
