A Configurable and Practical Remote Platform for Comprehensive Automotive Security Testing

Core Concepts
This paper proposes a flexible and configurable testing platform that enables easier access to test beds for efficient vehicle cybersecurity testing, including penetration testing, fuzz testing, and advanced security research.
The paper presents a new testing platform called the Vehicle Security Engineering Cloud (VSEC) Test that aims to address several challenges in the automotive cybersecurity testing and research domains. The key features of the platform include: Managed remote access via a web interface, allowing users to register and connect hardware test benches or vehicles to the cloud, which are then shared and managed centrally under an enterprise account. A configurable CAN bus network system that supports multiple bus speeds, multiple ECUs from multiple OEMs, and the ability to switch on/off the power of each ECU on-demand. Integration of measurement tools like oscilloscopes and logic analyzers, offering software control of these tools to enable advanced security testing. The paper discusses several testing methodologies enabled by this platform, including: Secure Development Lifecycle (SDL) testing, where the platform allows for continuous cybersecurity functional testing on components with over-the-air (OTA) update functionality. Penetration testing, where the platform enables "Partner Pentesting" by allowing remote engineers to work with local test engineers to perform physical interactions and execute tests. Research testing, where the platform provides a configurable environment for researchers to rapidly establish and experiment with numerous ECU networks to support their security research projects. The authors demonstrate the usefulness of the platform by implementing and testing three different open-source research projects using a single bench of ECUs, showcasing the platform's ability to enable advanced automotive security research.

This can involve simulating various V2X communication scenarios to identify vulnerabilities and ensure secure data exchange between vehicles and the surrounding infrastructure. Additionally, the platform can support the testing of security mechanisms such as certificate management, authentication protocols, and encryption techniques specific to V2X communication. By incorporating these features and test scenarios, the platform can provide a comprehensive testing environment for emerging automotive technologies, enabling researchers and engineers to evaluate the security posture of autonomous driving systems and V2X communication networks effectively.

What are the potential challenges in scaling this platform to support testing for a large number of OEMs and vehicle models simultaneously

Scaling the platform to support testing for a large number of OEMs and vehicle models simultaneously may present several potential challenges. One challenge is the diversity of hardware and software configurations across different OEMs and vehicle models, which may require extensive customization and configuration of the testing platform for each specific setup. This could lead to increased complexity in managing multiple test beds and ensuring compatibility with various ECUs and network architectures. Another challenge is the scalability of the platform to accommodate a large volume of test requests and users concurrently. As the platform expands to support testing for multiple OEMs and vehicle models, there may be an increased demand for resources such as hardware components, network infrastructure, and computational power. Ensuring the platform's performance and reliability under high load conditions while maintaining data security and user access control becomes crucial in such a scenario. Furthermore, interoperability issues between different OEM systems and protocols could arise when testing multiple vehicle models simultaneously. Ensuring seamless integration and communication between diverse ECUs, networks, and testing tools across various OEM platforms may require robust standardization and compatibility mechanisms to address potential conflicts and inconsistencies. Addressing these challenges will require careful planning, resource allocation, and technical expertise to scale the platform effectively and support testing for a large number of OEMs and vehicle models simultaneously.
