| description | The increasing number and complexity of cyber–physical systems in vehicles necessitate a rigorous approach to identifying functional safety and cybersecurity hazards during the concept phase of product development. This study establishes a systematic method for identifying safety and security requirements for E/E components in the automotive sector, utilizing the SysML language within the CAMEO environment. The method’s activities and work products are grounded in the ISO 26262:2018 and ISO/SAE 21434:2021 standards. Comprehensive requirements were defined for the method’s application environment and activities, including generic methods detailing the creation of work products. The method’s metamodel was developed using the MagicGrid framework and validated through an application example. Synergies between the two foundational standards were identified and integrated into the method. The solution generation was systematically described by detailing activities for result generation and the production of standard-compliant work products. To facilitate practical implementation, a method template in SysML was created, incorporating predefined stereotypes, relationships, and tables to streamline the application and enhance consistency. |
