ISO/SAE DIS 21434 Automotive Cybersecurity Standard - In a Nutshell

A range of connected and automated vehicles is already available, which is intensifying the usage of connectivity features and information sharing for vehicle maintenance and traffic safety features. The resulting highly connected networking amplifies the attractiveness level for attacks on vehicles and connected infrastructure by hackers with different motivations. Hence, the newly introduced cybersecurity risks are attracting a range of mitigating strategies across the automotive field. The industry’s target is to design and deliver safe and secure connected and automated vehicles. Therefore, efforts are being poured into developing an industry standard capable of tackling automotive cybersecurity issues and protecting assets. The joint working group of the standardization organizations ISO and SAE have recently established and published a draft international specification of the “ISO/SAE DIS 21434 Road Vehicles - Cybersecurity Engineering” standard. This document delivers a review of the available draft. This work provides a position statement for discussion of available analysis methods and recommendations given in the standard. The aim is to provide a basis for industry experts and researchers for an initial review of the standard and consequently trigger discussions and suggestions of best practices and methods for application in the context of the standard.
