Abstract
This paper presents ongoing research by Praxis High Integrity Systems into a contract-based approach to the definition and composition of dependability characteristics of components of complex systems. The research is founded on the Correctness By Construction methodology with the main aim being to assist in the construction of a demonstrably dependable system, and of its supporting dependability case for the purposes of safety certification and/or security accreditation. Other aims are to maximise re-use, accommodate COTS, and minimise impact of change across the whole lifecycle, including re-certification. The ongoing research is based on the results of an MoD-inspired project known as SafSec — an integrated approach to safety and security argumentation.
