The certification of road vehicle network security management system is based on ISO/SAE international standard 21434 "Road Vehicles - Network Security Engineering". Mainly regulate the network security issues in the electrical and electronic (E/E) system engineering of road vehicles. By ensuring appropriate consideration for network security, the aim is to enable the engineering of E/E systems to keep up with the latest technology and constantly evolving attack methods. The standard provides vocabulary, objectives, requirements, and guidelines related to cybersecurity engineering, serving as the foundation for a common understanding of the entire supply chain. This enables businesses to: establish cybersecurity policies and processes, manage cybersecurity risks, and cultivate a cybersecurity culture. Through ISO21434 certification, car manufacturers can demonstrate that their vehicles have reliable cybersecurity capabilities, thereby increasing consumer trust in their vehicles. At present, China's new energy vehicles are in an important stage of reshuffling after a major outbreak, and suppliers at all levels are constantly following the pace of vehicle manufacturers, with product prices and quality being "rolled up". Early deployment of network security by enterprises can also establish a firm foothold in the wave of automotive industry chain replacement in the future.

Detailed explanation of ISO21434 certification for road vehicle network security standards:

1. Network security risk management
ISO21434 certification emphasizes network security risk management throughout the entire lifecycle of vehicles. This includes identifying, assessing, and mitigating cybersecurity risks during product development, production, operation, and end-of-life stages. Through this approach, car manufacturers can ensure that their vehicles can withstand various potential cyber attacks and threats.
2. Security technology architecture design
ISO21434 certification requires automobile manufacturers to consider network security factors and establish a security technology architecture when designing vehicles. The architecture should include security components such as tamper proof measures, encryption technology, and firewalls to ensure that vehicles can respond quickly and mitigate potential damage in the event of a network attack.
6. Privacy Protection
ISO21434 certification also emphasizes that automobile manufacturers should protect user privacy. This means that car manufacturers should take measures to ensure that vehicles comply with relevant laws and regulations when collecting, storing, and using user data. In addition, automobile manufacturers should establish comprehensive privacy protection policies and processes to ensure the security and confidentiality of user data.
3. Network intrusion detection and response
ISO21434 certification emphasizes that automobile manufacturers should have effective network intrusion detection and response capabilities. This includes measures such as real-time monitoring of vehicle networks, detecting and responding to potential network attacks, and updating security patches in a timely manner. Through this approach, car manufacturers can ensure that vehicles can respond quickly and mitigate potential damage in the event of a cyber attack.
4. Training of personnel safety awareness
ISO21434 certification requires automobile manufacturers to strengthen the cultivation of employees' awareness of network security. Employees should understand the importance of network security, master network security knowledge and skills, and be able to effectively respond to potential network threats in their daily work. In addition, automobile manufacturers should establish comprehensive cybersecurity training programs to enhance employees' understanding of the latest cybersecurity threats.
5. Supply chain security management
ISO21434 certification emphasizes that automobile manufacturers should ensure supply chain security. This means that car manufacturers should strengthen their supervision and management of suppliers, ensuring that they have sufficient network security capabilities and provide safe and reliable components and solutions. In addition, automobile manufacturers should establish close cooperative relationships with suppliers to jointly respond to potential cyber threats and attacks.
