New generation of car network security escort SDP and blockchain technology is the key

The advent of self-driving cars has revolutionized the entire automotive industry. This change brought new opportunities for the entire industry, but it also brought new risks - especially network security. Because self-driving cars rely entirely on networking software to perform all aspects of their operations, they are vulnerable to a large number of cybersecurity attacks. As we see in the news every day, even established industries such as the financial industry and government agencies are still struggling to deal with the same problems. Afterwards, the automotive industry must go beyond existing cybersecurity measures to ensure that not only all existing threats are mitigated, but that future "unknown" threats are also prevented.

Car network security is far more than ransom, data leakage, personal records, etc., but it is about the safety of our lives!

The U.S. Congress recently approved a cyber security bill for cars, the "Self-Drive Act," and the Senate's progress on the AVSTART Act has sent a clear signal that the car The industry needs to take network security seriously and must address the direct security risks of connected cars and the long-term risks of self-driving cars. The Automated Driving Act outlines cyber security plans for automated driving systems.

Traditionally, the auto industry uses only mature technology. Unfortunately, the rapid development of software development requires that the automotive industry become more innovative in how it views software. More importantly, the dramatic increase in cybersecurity attacks requires cooperation between OEMs, tier one suppliers, software developers, and cybersecurity companies to reach an unprecedented scale. Today's car network security technology is at best the market after all. There are still many unresolved issues, including how to protect internal vehicle systems from attacks and ensure data integrity, while also providing data privacy and secure vehicle-to-cloud communication for millions of cars, all of which support hundreds of vehicles. ECUs, sensors, domain controllers, radar, lidar, and ADAS. In order to provide network security technologies to solve these specific problems of networked vehicles and autonomous vehicles, many factors must be considered, such as the global scale of a large number of vehicles, detection of tampering software and malware, support for a range of remote information, and information. And security applications that provide precise access control to vehicle software vendors and comply with regional security, privacy and driving regulations.

Fortunately, there are two emerging technologies, software-defined perimeter (SDP) and blockchain, which are very helpful in solving automotive network security issues. SDP provides secure communication between software processing and cloud hosting applications inside the vehicle, while blockchain supports secure messaging. By combining any combination of SDP with the scale of the blockchain, an efficient network security model for networked and self-driving vehicles can be created.

In order to more systematically provide the required safety for networked vehicles and self-driving vehicles, several measures should be taken:

Integrate the industry-wide automotive network security life cycle compliance certification program, and make network security a mandatory part of the automotive product development process;

Establish a joint car network security working group responsible for proactively preventing, mitigating and correcting threats;

Provides regulatory agency access to vehicle metadata (non-personally identifiable information) for random network security checks and verification.
