Abstract
On April 1, 2025, the Chinese vehicle networking industry will witness a historic moment—the national standard “Detection Mechanism for Abnormal Behavior in Vehicle Networking Security” (GB/T 45181-2024) will officially be implemented!This standard, led by 360 Group and the China Academy of Information and Communications Technology, was jointly developed with industry giants such as China Mobile, Baidu, Tencent, FAW, and Changan, marking the entry of China’s smart automotive network security into the “proactive defense” era.
The New National Standard for Vehicle Networking Security is Here, and Smart Cars Face a “Safety Test”
01
Why is this standard necessary?
With the popularity of smart cars, vehicles are no longer just simple means of transportation; they have become “mobile data centers” connecting to the cloud, roadside devices, and user terminals. However, threats such as hacker attacks, data breaches, and system hijacking are ever-present. For instance, there have been cases where vehicles were remotely controlled to brake due to vulnerabilities, or billboards were misidentified as obstacles, leading to accidents. The core goal of the new national standard is to identify risks and intercept them before attacks occur through an “abnormal behavior detection mechanism,” safeguarding driving safety and user privacy.
02
How will the new national standard change the industry?
Companies must “upgrade their technology”: Intrusion detection, encrypted communication, and AI-driven threat analysis will become standard for automotive manufacturers. Models that do not meet the standards may face the risk of being eliminated from the market.
Collaborative defense across the industry chain: Automotive manufacturers, communication operators, and internet companies need to build a secure ecosystem together, such as sharing threat intelligence and establishing unified emergency response processes.
Enhanced user rights: In the future, network security performance may become one of the core considerations for consumers when purchasing vehicles, forcing automotive companies to be transparent about their security capabilities.
03
Global Perspective: The “Offensive and Defensive Battle” in Vehicle Networking Security Upgrades
International Benchmarking: At the 2025 CES, South Korea’s AUTOCRYPT showcased V2X communication encryption technology, emphasizing “three-stage security verification.”
Gartner’s Predictions: Among the six major trends in cybersecurity predicted for 2025, machine identity management and AI strategic deployment will become focal points, highly related to vehicle networking security. For example, if the machine identity relied upon by autonomous driving systems is hijacked, it could lead to catastrophic consequences.

Must-Read for Car Owners: How to Protect Your Smart Car?
Regularly Upgrade the System: Ensure that security patches pushed by automotive manufacturers are installed promptly.
Be Cautious of Unknown Device Connections: Avoid using unofficial in-car applications or connecting unknown hardware.
Pay Attention to Data Permissions: Limit apps’ access to sensitive vehicle data (such as location and camera).
Conclusion
The “National Standard Era” of vehicle networking security has arrived. This battle concerning the lives and data of billions of car owners has no bystanders. Whether companies or individuals, only by actively embracing change can we drive towards a safer future.
