Cyber-physical systems are attracting a lot of attention: attacks on connected cars received a lot of media exposure, as did attacks on industrial control systems, medical devices, and more generally on IoT devices. A lot of this interest is driven by vulnerability research (often in the form of "stunt hacking"). While useful and frankly engaging and attractive, this research does not really help answer the fundamental question of how to embed security analysis in design. In this talk, we will use automotive security as a case study to try to outline a risk-based design methodology that can be used to deal with our hyper-connected future.
