(2) Make a change plan for major configuration changes and conduct impact analysis, and conduct strict safety tests before the configuration changes are implemented.
(3) Pay close attention to major security vulnerabilities in the vehicle network and take timely software upgrade measures. Before the upgrade, the software needs to undergo a rigorous security assessment and test verification.
(4) If remote upgrade is required, the upgrade process must be carried out under the conditions of system security, with communication security (such as authenticity, integrity, confidentiality, etc.), as well as the ability of abnormal detection and response, and need to obtain user confirmation. And the upgrade process needs to record complete log information (including service platform, vehicle-side equipment, human-computer interaction activities, etc.).
Third, border security protection
(1) Separating the development, testing and production environment of the vehicle networking system.
(2) In the design of vehicle architecture, network segmentation and isolation techniques are adopted. Perform boundary control (such as whitelist, data flow, data content, etc.) on different network segments (such as different types of networks inside the vehicle, as well as mobile communication networks for vehicles and external communications, etc.), and data entering the vehicle's internal control bus. Safety control and safety monitoring.
(3) Vehicle-side critical network border devices (such as T-BOX, gateway, etc.) need to provide boundary security protection functions (such as firewall, intrusion detection, intrusion prevention, and limit diagnosis and other non-standard traffic).
(4) Vehicles and external communications adopt secure access methods (such as VPN), and can divide services and access the network through different secure communication subsystems.
(5) The service platform needs to have security functions such as firewall and intrusion detection.
Fourth, physical and environmental security protection
(1) The service platform computer room is located in China. The equipment room selection, design, power supply, fire protection, temperature and humidity control, etc. meet the requirements of relevant national standards, and the physical security protection measures such as access control, video surveillance, and special personnel shall be taken for the equipment room; public cloud is adopted. Service mode service platform, choose cloud service providers to meet the relevant national standards.
(2) Configuring and accessing all access points (such as Bluetooth, USB, CD, diagnostic interface, debugging interface, positioning system, TPMS radio frequency communication, car key radio frequency communication, RFID, etc.) of the vehicle end equipment (such as whitelist, Data flow, data content, etc.).
V. Identity authentication
(1) Use identity authentication management in the process of vehicle opening, mobile APP login, service platform access, etc. In key business scenarios (such as remote upgrade, remote control, etc.), multi-factor authentication is used (such as static password authentication, dynamic password authentication, key-based authentication, biometric identification, etc.).
(2) Implement real-name identity (based on name, ID number, VIN number, mobile) in the user registration process of car SIM, car networking application (mobile terminal APP, car terminal APP, etc.) in accordance with the principle of “real name in the background and voluntary at the front desk” Phone number, etc.) registration.
(3) The service platform is reasonably classified to set account rights, and the account rights are assigned in the principle of least privilege.
