Cybersecurity Becomes Core Automotive Engineering Discipline
Cars are becoming more like computers, with lots of software and connectivity.
This makes them vulnerable to hackers who could take control of important systems like braking and steering.
To keep cars safe, manufacturers need to build security into every part of the car, from the software to the communication systems.
There are also rules and standards that companies must follow to ensure their cars are secure.
This means cybersecurity is now a crucial part of making cars, not just an extra feature.
Automotive engineering has shifted from hardware-centric to a multidisciplinary integration of software, hardware, and electronics.
Software-Defined Vehicles (SDVs) require robust cybersecurity to protect against remote exploitation of critical systems.
Automotive cybersecurity involves threat analysis, risk assessment, and secure-by-design development frameworks.
Regulations like UN R155, R156, and ISO 21434 mandate cybersecurity and software update management systems for vehicle manufacturers.
Manufacturers must adopt a proactive, secure-by-design philosophy to ensure vehicles are both technologically advanced and secure.
