As vehicles evolve into software-driven, connected systems combining embedded software, sensors, electronic control units, and remote capabilities, automotive cybersecurity has become critical to the entire development lifecycle. Modern vehicles feature multiple digital interfaces including Bluetooth, Wi-Fi, cellular communication, infotainment systems, and Over-the-Air (OTA) updates, each creating potential vulnerabilities that could compromise vehicle functions, data confidentiality, and system integrity. Automotive cybersecurity now encompasses processes, technologies, and engineering practices to identify, assess, and mitigate digital risks throughout vehicle systems. The industry has adopted "security by design" principles, addressing cybersecurity requirements from early development stages rather than adding protection retroactively. ISO/SAE 21434 serves as a key international standard, requiring cybersecurity risk management across the entire lifecycle of electrical and electronic systems, from concept through decommissioning. Additionally, regulatory frameworks including UN R155, which establishes vehicle cybersecurity and Cyber Security Management Systems requirements, and UN R156, addressing software updates, demonstrate that automotive cybersecurity is now an engineering discipline rather than an IT afterthought.
