Challenges
Tailoring cybersecurity solution for OEM Needs
Our team was tasked with adapting the parking brake actuator to meet OEM security requirements. This involved implementing and documenting agreed security features resulting from threat modeling, and dependent concepts originating from specified security controls to ensure their functionality over the entire product lifecycle. Key tasks included performing a TARA and creating cybersecurity specifications for various security controls.

Comprehensive Security Integration
Comprehensive Security Integration
In our assessment of the parking brake actuator, we conducted a comprehensive Threat Analysis and Risk Assessment (TARA) to identify potential cybersecurity threats and vulnerabilities.
This involved a systematic evaluation of the actuator's architecture, interfaces, and operational environment to determine possible attack vectors. By analyzing the potential impact and likelihood of various threats, we were able to prioritize risks and develop appropriate mitigation strategies.
We integrated and documented multiple security features into the parking brake actuator. These included the integration of SecOC and Freshness Value Manager for secure CAN communication, token-based diagnostic security management for the UDS interface, and IVD for flash data validation. Hardware-based security controls were incorporated at the PCBA assembly level, along with Debug Interface Security Controls to prevent access to debug interfaces.
The VKMS was integrated to manage key flashing and lifecycle management, and SW update security mechanisms were added to secure flash updates. Immobilizer features and on-chip HSM configuration were also implemented to provide a Trusted Execution Environment and secure storage of security materials. Additionally, we assisted with writing test cases for cybersecurity requirements.
Results
Tailored security features
Our efforts resulted in the successful adaptation of the parking brake actuator to meet OEM security needs. This included the integration of multiple security features, thorough documentation, and the development of test cases for cybersecurity requirements. The project ensured secure CAN communication, UDS interface, flash data validation, key management, and overall product security, enhancing the actuator's compliance with OEM and cybersecurity standards.
Our comprehensive integration of security features into the parking brake actuator project ensured compliance with OEM requirements, improved product security, and provided robust documentation and test cases to support cybersecurity throughout the product lifecycle.
