Interactions Between Functional Safety and Cybersecurity
Even a cursory survey of electronic control units (ECUs) in a typical vehicle will reveal that the majority of these ECUs are safety-relevant. Whether it is braking, steering, propulsion, or battery management, there is barely a vehicle system where maintaining safety is not a primary objective. Whenever a system is subjected to safety hazards, a whole suite of engineering practices and methods is employed to achieve the required level of safety integrity. These practices aim to eliminate unreasonable safety risks that would lead to harming a human being while the system was in use. Engineering safety-critical systems that are also resilient to cyberattacks adds a new dimension to automotive ...
