Disentangling the relations between safety and security
Ludovic Piètre-Cambacédès, Claude Chaudet · 2009
This article aims at a finer apprehension of the relations between safety and security, which are intrinsically and increasingly intricate. We introduce a new conceptual framework to better capture their moving perimeters. Then, we present our on-going work to characterize safety and security interactions, varying from reinforcement to strong antagonism. A property decomposition analysis and its limits are discussed; research tracks are finally identified. Key-Words: Security, safety, dependability, computer security, safety systems, SIS, industrial control systems
