A common requirement for modern distributed and reactive systems is a high dependability guaranteeing reliability and security. The rigorous analysis of dependable systems specifications is of paramount importance for the reliability and security of these systems. A two-layered modal specification notation will allow the specification of services and protocols for distributed dependable systems and their properties. Refinement and its dual — abstraction — will play the key roles in an integrated development and analysis framework. Refinement and abstraction form the basis for an interference analysis method for security properties and for automated test case generation.
