Secure Open Source: Powering Innovation in the Automotive Industry

The automotive industry is currently experiencing a digital revolution, where software has become the central component of modern vehicles. Open source software (OSS) is pivotal in driving this transformation, powering functionalities such as connected car features, AI, and autonomous driving. However, the integration of OSS presents unique security challenges that necessitate a robust security posture.

The Impact of Open Source in Automotive

The rise of open source adoption in the automotive sector is evident and accelerating. This trend is propelled by various factors:

• Faster Innovation: Open source fosters collaboration and rapid development cycles, essential for keeping pace with technological advancements in the automotive industry.

• Reduced Costs: Leveraging open source components can significantly diminish software development expenses for automotive manufacturers.

• Access to Expertise: Open source communities provide a vast pool of talent and expertise that automotive companies can tap into.

Open Source in Action

Leading companies in the transportation industry leverage open source projects for various functionalities. Here are a few examples:

• Uber (Ride-hailing):

  • Navigation: Uber relies on open source projects like OpenStreetMap for accurate and up-to-date map data, crucial for their ride-hailing services.

  • Data Management: Apache Hadoop, a popular open-source framework, empowers Uber to manage and analyze the massive amount of data generated by its operations.

• Tesla (Electric Vehicles):

  • Machine Learning: Tesla leverages open source projects like TensorFlow, a powerful machine learning library, to develop and train algorithms for tasks like autonomous driving and autopilot features.

  • Data Visualization: Matplotlib, an open-source library, allows Tesla to effectively visualize and analyze the data collected from their vehicles, aiding in engineering and development processes.

• Toyota (Traditional Automaker):

  • Linux Foundation Automotive Grade Linux (AGL): Toyota is a member and contributor to the AGL project, a collaborative effort to create a stable, secure, and open Linux distribution specifically designed for automotive applications. This allows them to leverage a robust open source foundation while tailoring it to their specific needs.

  • Eclipse Automotive Working Group: Toyota also participates in the Eclipse Automotive Working Group, which develops open source tools and frameworks for in-vehicle software development. This grants them access to a wide range of tools for various automotive software functionalities.

These examples showcase the prevalence of open source throughout the automotive industry, with applications ranging from core functionalities to cutting-edge features.

Open Source Communities and Foundations

Strong open source communities and foundations like AGL and the Eclipse Foundation play a crucial role in advancing automotive software development. They provide resources, promote collaboration, and foster innovation within the industry.

Promising Open Source Community Projects for Automotive

The automotive open source community is brimming with innovative projects:

1. Eclipse Automotive Working Group: Develops open source tools and frameworks for tasks like in-vehicle software development, diagnostics, and testing, adhering to automotive safety standards.

2. ROS (Robot Operating System) 2 for Autonomous Vehicles: Provides a robust framework for developing and deploying software for autonomous vehicles, leveraging the power of the ROS community and its focus on real-time systems.

3. OpenXC: An open source framework for connecting to and controlling vehicle Electronic Control Units (ECUs), enabling developers to build custom applications for research, diagnostics, and potentially teleoperation applications.

4. Automotive Grade Linux (AGL) Security Working Group: This group focuses on developing and maintaining security best practices for the AGL operating system, a popular open source platform powering many automotive in-vehicle infotainment (IVI) systems.

Security Concerns and the Automotive Landscape

Unlike traditional software, vulnerabilities in automotive OSS can have life-or-death consequences. A single exploit could compromise vehicle control systems, steal sensitive data, or disrupt critical operations. Furthermore, automotive software development adheres to strict safety standards like ISO 26262.

Security tools for open source need to be tailored to this rigorous environment, accounting for:

1. Compliance Integration: Security assessments need to seamlessly integrate with existing automotive development lifecycles and regulatory compliance workflows.

2. Deep Vulnerability Scans: Tools should go beyond basic vulnerability checks and delve into industry-specific threats and potential exploits targeting automotive systems.

3. License Management: Compliance with open source licenses is crucial for long-term project sustainability and legal risk mitigation. Security tools should efficiently manage and track licenses used within automotive software.

Fortunately, the open source community recognizes these unique needs and has developed several innovative tools specifically designed for automotive security:

1. Open Source Security Foundation (OpenSSF) Scorecard: This project helps assess the security posture of open source projects based on industry best practices. It allows developers to identify areas for improvement and prioritize remediation efforts within the automotive context.

2. SPDX (Software Package Data Exchange): This open standard facilitates the creation of machine-readable software bills of materials (SBOMs). SBOMs provide a comprehensive inventory of all software components, including open source dependencies, essential for license compliance and vulnerability management in automotive projects.

Organizations within the automotive domain exhibit varying levels of open source maturity. Some are just embarking on their open source journey, while others have established mature Open Source Program Offices (OSPOs) to effectively manage their OSS usage.

The Critical Role of OSPOs

An OSPO is a dedicated team within an organization responsible for governing the use of open source software. Benefits of establishing an OSPO in the automotive industry include:

• Reduced Security Risks: Proactive vulnerability management and secure open source integration practices minimize security vulnerabilities in automotive software.

• Improved Compliance: Established processes ensure compliance with open source licenses, thereby averting legal issues.

• Faster Innovation: Streamlined OSS management enables developers to leverage the latest open source technologies and accelerate innovation.

• Enhanced Collaboration: Effective OSPO fosters collaboration between internal teams and open source communities.

Setting Up an OSPO for Automotive

To establish an OSPO for your automotive organization, follow this roadmap:

1. Define Goals and Scope: Outline the OSPO's purpose, focusing on areas like security, compliance, and collaboration specific to the automotive domain.

2. Assemble the Team: Identify key personnel with expertise in legal, development, security, and open source communities.

The Need for Open Source Security Labs

The vastness of the open source landscape makes it challenging to maintain in-house expertise for all components used. An OSPO can leverage an open-source security lab powered by a platform like BeSLab. BeSLab empowers organizations to:

• Curate Open Source Projects of Interest (OSSPoI): Focus on the specific open source projects your automotive software relies on.

• Track Vulnerabilities of Interest (OSSVoI): Stay updated on vulnerabilities impacting your chosen OSS components.

• Leverage AI Models of Interest (OSSMoI): Utilize AI-powered tools to streamline vulnerability assessments.

Beyond security labs, Open Source Assurance Service Providers (OASPs) play a critical role in mitigating security risks within the automotive industry due to the unique safety considerations

Open Source Security Vulnerabilities and OASP Support

Recent vulnerabilities like Log4Shell highlight the critical need for vigilant security practices. An Open Source Assurance Service Provider (OASP) can help automotive organizations:

1. Stay Informed: OASPs keep you updated on the latest vulnerabilities and their potential impact on automotive systems.

2. Prioritize Remediation: OASPs help prioritize patching critical vulnerabilities based on exploit likelihood and severity.
