Key Components of Telematics Infrastructure

1. Telematics Control Units (TCUs): These are embedded devices that collect and transmit data to a central system. They often use cellular networks or WiFi to ensure secure communication.
2. Communication Protocols: Protocols like CAN Bus or TCP/IP are fundamental in managing how data is transmitted between devices. However, the lack of encryption in CAN Bus systems makes vehicles vulnerable to cyberattacks.
3. Cloud and Edge Computing: Data collected from telematics devices is often stored and processed in the cloud for scalability, or at the network edge for reduced latency.
4. Encryption Mechanisms: To protect data from unauthorized access, telematics systems use AES or RSA encryption during transmission and storage. For more details, refer to our encryption glossary article.

Cybersecurity Challenges in Telematics Infrastructure

Key Risks

• Data Interception: As telematics data is transmitted over public networks, there's always a risk of man-in-the-middle attacks where attackers intercept data during transmission. Using robust encryption helps mitigate this risk.
• Remote Hacking: Connected cars and devices that use CAN Bus are vulnerable to remote hacking due to a lack of inherent encryption. In some cases, hackers have remotely controlled vehicles, highlighting a serious gap in vehicular cybersecurity. Read more on this in our cyber resilience blog post.
• Firmware Vulnerabilities: If the firmware of telematics devices isn’t updated regularly, they can become a target for cyberattacks. Firmware signing is essential to ensure only trusted updates are installed.

Best Practices for Securing Telematics Infrastructure

1. Encryption: Always use encryption for both data in transit and at rest. Encryption standards such as AES are recommended.
2. Intrusion Detection Systems (IDS): Deploying an IDS helps monitor network traffic and identify unusual activities that could indicate an attack.
3. Regular Updates: Firmware and software updates are crucial to patching known vulnerabilities. These updates should be signed to ensure their authenticity.
4. Network Segmentation: Segregating telematics networks from other networks prevents lateral movement by attackers who have compromised a single entry point.
