Abstract

Modern industrial control systems become increasingly interconnected and
rely on external networks to provide their services. Hence they become
vulnerable to security attacks that might directly jeopardise their
safety. The growing understanding that if the system is not secure then
it is not safe calls for novel development and verification techniques
weaving security consideration into the safety-driven design. In this
paper, we demonstrate how to make explicit the relationships between
safety and security in the formal system development by refinement. The
proposed approach allows the designers to identify at early design
states mutual interdependencies between the mechanisms ensuring safety
and security and build robust system architecture.
