The new automotive network architecture exposes more and more automotive electronic components while meeting the needs of big data transmission. A wider extension brings better applications and experiences, as well as more attack entrances. How to carry out comprehensive system protection and division of protection functions has become a problem that needs to be solved in the future of automotive networks. Establishing the information security management requirements for the construction of all ICVs, formulating ICV information security technical standards and information security testing specifications, and establishing an ICV information security emergency response system have become issues that need to be solved in the future for intelligent network vehicles. It is a protracted battle that the government and enterprises must actively deal with.
