Abstract. Traditionally, safety and security have been treated as separate disciplines, but this position is increasingly becoming untenable and stakeholders are beginning to argue that if it's not secure, it's not safe. In this paper we present some of the work we have been doing on "security-informed safety". Our approach is based on the use of structured safety cases and we discuss the impact that security might have on an existing safety case. We also outline a method we have been developing for assessing the security risks associated with an existing safety system such as a large-scale critical infrastructure.
Bloomfield et al. REF mention a security-informed risk assessment with a focus on a "security-informed safety case" and the impact of security on an existing safety case.
