abstract
Our lives become increasingly dependent on safety- and security-critical systems, so formal techniques are advocated for engineering such systems. One of such techniques is validation obligations that enable formalizing requirements early in development to ensure their correctness. Furthermore, validation obligations help hold requirements consistent in an evolving model and create assurances about the model's completeness. Although initially proposed for safety properties, this paper shows how the technique of validation obligations enables us to also reason about security concerns through an example from the medical domain.

From What to How: A Taxonomy of Formalized Security Properties
The authors propose an SDLC taxonomy that refines first-level security properties into design-level sub-properties, and formalize a subset in Event-B to check consistency.
