This whitepaper highlights that as vehicles become software-defined and increasingly connected, cybersecurity must be embedded across every layer of the system rather than treated as an afterthought. It outlines a structured, risk-based approach that includes secure over-the-air updates, secure boot processes, and multi-layered network protection using technologies like MACsec, IPsec and TLS. The paper emphasizes the importance of industry standards and regulations such as UNECE frameworks, along with practices like public key infrastructure for software validation. Ultimately, a comprehensive cybersecurity management system is essential to protect vehicle functionality, ensure safe data exchange, and maintain trust as vehicles evolve into highly connected digital platforms.
