Dependability encompasses different classes of system properties, related to security, reliability, or safety. This paper examines the relevance of the security concept of noninterference to safety-related properties, and, conversely, the applicability of fault-tolerance mechanisms usually applied to provide safety and reliability in the security domain. We suggest promising lines of research in the intersection of safety and security, in the application of security concepts and models to different classes of safety or fault-tolerance properties, and in the theory and practice of fault-tolerant systems applied to intrusion tolerance.
