Automotive cybersecurity fully revealed

Security needs to be taken into account from the start and at every step of development, ensuring compliance and a robust security architecture. Whether in DevSecOps or the V-model, early security focus minimizes costly rework later on. Following the security-by-design principle builds resilient software, continuously optimized for today’s evolving threats, reducing time needed to address vulnerabilities.

Defense in depth ensures that no single point of failure compromises security by implementing multiple protective layers. Traditional E/E architectures used hardware-based separation, while today’s centralized architectures and vehicle cloud computing demand additional “virtual” layers. This shift ultimately moves towards a zero-trust security model, addressing the increased complexity of modern vehicle systems.

With rising cybersecurity risks, targeted management is essential. For example, the performance of a threat analysis and risk assessment (TARA) is a main component within the ISO/SAE 21434 standard. It gives manufacturers and suppliers a blueprint to find potential threats and develop appropriate protective measures. The general goal is to achieve the lowest possible threat level, e.g. through consistent application of the security by design and defense in depth principles. Evolving threats and open ecosystems demand updated tools and processes beyond traditional development systems.

Achieving cyber resilience requires a company-wide shift toward proactive cybersecurity awareness, teamwork, and flexibility beyond checklist-driven approaches. Legal frameworks like the UNECE regulation mandate a comprehensive cybersecurity management system (CSMS) covering operations, risk management, and internal audits. By adopting the "Three Lines of Defense" approach, security becomes integrated across all departments, processes, and product lifecycles, engaging stakeholders and the entire supply chain.
