Security crash test - practical security evaluations of automotive onboard IT components
(Automotive - Safety & Security 2014, 2015) Bayer, Stephanie; Enderle, Thomas; Oka, Dennis-Kengo; Wolf, Marko
Modern vehicles consist of many interconnected, software-based IT components which are tested very carefully for correct functional behavior to avoid safety problems, e.g. that the brakes suddenly stop working. However, in contrast to safety testing systematic testing against potential security gaps is not yet a common procedure within the automotive domain. This however could eventually enable a malicious entity to be able to attack a safety-critical IT component or even the whole vehicle. Several real-world demonstrations have already shown that this risk is not only academic theory [1]. Facing this challenge, the paper at hand first introduces some potential automotive security attacks and some important automotive security threats. It then explains in more detail how to identify and evaluate potential security threats for automotive IT components based on theoretical security analyses and practical security testing. Lastly, we propose “automotive security evaluation assurance levels” (ASEAL) which define up to four discrete security testing levels.
