Autonomous vehicle engineers have an obligation to do everything they can to defend against firmware threats. If nothing else, they need to protect themselves. Selling vehicles that are later revealed to have vulnerabilities is expensive and scars the company’s reputation. Instead of taking a reactive approach, OEMs should develop robust internal processes for firmware development and ongoing risk mitigation.
Protection from the Start: Design and DevelopmentFirmware development across any device is a resource-intensive project. Add in the elements of numerous interacting systems and devices within a single vehicle, and the complications increase exponentially. However, proper firmware development is of the utmost importance as it is the first line of defense against attacks. Given the recent developments in autonomous vehicles, especially at the L4 and L5 levels, it is particularly challenging to find individuals or teams with the right expertise.
Never Let Your Guard Down: Ongoing Risk Mitigation
Industry Group and Public Sector SupportLuckily, firmware risk has already been significantly mitigated thanks to the work done by industry groups and public sector organizations. These groups have already invested a lot of resources into developing and promoting firmware standards and specifications to help improve security, including cybersecurity in autonomous vehicles. For example, the Unified Extensible Firmware Interface Forum publishes the UEFI specification, including the UEFI Secure Boot protocol. In addition, the Trusted Computing Group (TCG) designs hardware that can store and protect platform secrets like encryption keys and other data that need to be secure. For cybersecurity in autonomous vehicles specifically, the following groups are developing critical baseline security standards:
- Automotive Cybersecurity Industry Consortium (ACIC)
- Automotive Information Sharing and Analysis Center (Auto-ISAC)
- Alliance for Automotive Innovation
- SAE International
Understanding the Responsibility of Cybersecurity in Autonomous VehiclesWhile the work and support from these groups are of great use to the industry, it is still up to automotive manufacturers to:
- Build secure firmware based on industry best practices
- Implement recommendations and standards
- Monitor all of the specifications and vulnerability alerts
- Develop and distribute patches for vulnerabilities once they become aware of them
Unfortunately, not all organizations have the expertise to establish a secure development process as well as perform ongoing risk mitigation.Some OEMs are diligent about firmware patching. They may even have an automated firmware updating service that pushes patches to end-user devices. However, not all OEMs patch firmware. This is not a healthy state of affairs, but it is very real. This deficiency can be due to a lack of resources, expertise, or both. The result is a firmware ecosystem that is rife with unremediated vulnerabilities.
