TMC-Drive is a cutting-edge autonomous electric vehicle designed for urban use, supported by in-house software, mobile connectivity, and a cloud backend. For this exercise, our team focused on the cloud hosting backend, which powers essential services like remote control, OTA updates, and data storage.
By applying industry-recognized threat modeling frameworks, we identified several high-impact risks affecting security, privacy, and system integrity — including issues with update mechanisms and cryptographic key management. The findings that follow highlight the most critical threats uncovered in our analysis.
After identifying the key threats, we developed a treatment plan that includes a total of 54 detailed countermeasures. The list that follows highlights the most significant ones — those that either mitigate critical threats or offer protection against multiple risks at once.
By applying the proposed countermeasures, the business can significantly reduce its elevated risk profile to a much more manageable and acceptable level, strengthening the security, reliability, and trustworthiness of the cloud backend that supports TMC-Drive.
