The first three mechanisms constitute basic building-blocks of the architecture, and the fourth one corresponds to a major innovation. The formal approaches applied include both . and ..

The notions of multiple integrity levels and multiple criticality levels are very tightly linked, but there is an important distinction. Integrity levels are associated with an integrity policy that defines what is allowed in terms of data flow bet

This chapter describes the Architecture Development Environment (ADE) designed to support the GUARDS methodology through a set of integrated tools for the consistent management of all dependability information and properties, and at the same time offering specific features which add
