Automotive Cybersecurity
Engineering discipline that protects vehicle electronics, software, and lifecycle data from attackers.
Automotive Cybersecurity covers the practices, tooling, and engineering evidence required to design, deliver, and maintain road-vehicle systems against intentional cyber attacks. It spans organisational processes (CSMS), vehicle-level analysis (TARA), implementation (secure boot, secure diagnostics, secure communication), validation (penetration testing, fuzz testing), and post-development monitoring (vulnerability handling, incident response). It is anchored by ISO/SAE 21434 and enforced for type approval by UNECE R155 and R156, with regional derivatives such as India's AIS 189 and AIS 190.
Why it matters
Connected and software-defined vehicles concentrate the attack surface across ECUs, in-vehicle networks, OTA channels, and backend services. Without a structured cybersecurity engineering programme, type-approval evidence cannot be produced and field issues cannot be triaged consistently.
