The Results

Developing Secure Infotainment Systems Faster

  All business-critical bugs found within a week
  Increased code coverage to over 95% in most modules
  Big steps towards ISO 21434 compliance
  Improved bug reporting

"Only 1% of all our security tests done for the project where CI Fuzz was used were fuzz tests, but through them, we find about 57% of all vulnerabilities."

1. Realizing Modern Security Tests in An Embedded Automotive Architecture

Continentals HMI business unit develops embedded systems and solutions for the human-machine interface of modern road vehicles. For example, display solutions, head-up displays and cockpit high-performance computers. HMI makes processing and managing information simple, intuitive, and reliable.

Infotainment systems in modern vehicles usually communicate with a whole range of external embedded sensors. These dependencies add an additional layer of complexity for security testing, as they typically require plenty of manual effort.


Writing Test Harnesses

Although the Public API documentation is usually available, developers need to write plenty of test harnesses, which is incredibly time-consuming. 

Hardware Dependencies

Developers have to secure the communication between the Hardware-Dependent-API and the hardware.

2. Complying With ISO 21434/UNECE WP.29

As a result of the new ISO/SAE 21434 and UNECE WP.29, many car producers (OEMs) are extending their software testing activities. The standard holds regulations for software devices within vehicles, along with their connectivity to external systems.

Implementing Fuzz Testing

ISO 21434 and UNECE WP.29 recommend OEMs integrate feedback-based fuzz testing into their DevOps processes and define new requirements for software security engineering.

How to Get the Developers on Board

Open-source fuzzing solutions are already very effective, but they still require manual tuning and follow-up work for developers. Continental was looking for a professional fuzzing solution they can easily apply in automotive architecture.

The Solution

CI Fuzz Testing Platform

Continental implemented the CI Fuzz testing platform in their CI/CD to improve their code quality and development speed. CI Fuzz is a CI/CD-agnostic platform for automated security testing. The platform helps developers protect themselves against unexpected edge cases. It empowers them to fix bugs during development and to achieve reproducible testing results.

The Success

Fuzzing Embedded Systems With Dependencies

The CI fuzz testing platform makes it possible to apply modern fuzz testing approaches in an early stage of the software development process. This has automated and simplified the entire testing process because it enabled the developers to perform security tests on their own modules and to fix critical bugs right away.

The CI Fuzz testing platform also enabled the developers to mock their hardware with fuzz data. By applying feedback-based fuzzing many developers at Continental are now able to protect their software against edge cases and unexpected behaviors. For example, if a sensor should send unusual or erroneous inputs.


Get Started With CI Fuzz

Implementing CI Fuzz helped Continental to significantly improve the quality and security of their software while getting them one step closer to ISO 21434 compliance.
