Developing Secure Infotainment Systems Faster
"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.

How to Get the Developers on Board
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.
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.
