Abstract :
The paper discusses modeling assessment aspects of incorporating security into an embedded system. The essential assumption in the approach and the model we propose is that a security breach may cause degradation of the service and ultimately a failure. The security model concentrates on the system´s interaction with the environment via a communication channel. The cooperative adaptive cruise control (CACC) system is used as a case study. The results of the study obtained for availability assessment due to security lapses show that a modeling technique may be used to evaluate the need for appropriate mitigation mechanisms allowing the system to withstand the attacks still assuring desired level of availability.
