In this paper, we propose an integration of the Unified Process and a Dependability Analysis and Modeling (DAM) profile to support quantifiable, testable reliability and availability requirements (R & AR) elicitation and completeness analysis. Specifically, we are interested in improved identification and specification of R & AR and their associated assumptions. This is accomplished through an iterative workflow that is consistent with the Unified Process and attaches DAM stereotypes to use and misuse cases. Fault-tree analysis helps determine and mitigate combinations of faults that could impede R & AR achievement. The workflow steps are demonstrated and evaluated on an intrusion protection service for critical infrastructures.
