Fuzzing Automotive Software

Automotive developers need to automate their security testing, due to the high complexity and interconnectivity of modern vehicles. 

Comply With ISO 21434

Due to the new ISO/SAE 21434 and UNECE WP.29, many car manufacturers (OEMs) are expanding their software testing activities. The standard contains regulations for software devices within vehicles, as well as their connectivity to external systems.

Download this Cheat Sheet for 6 simple tips that will help you comply with the upcoming ISO 21434 norm.

5 Drivers of Change in Automotive Software Security

Due to the rapid speed at which the automotive industry is evolving, state-of-the-art application security testing is an absolute precondition to stay competitive. Traditional software testing approaches are insufficient for today’s complexity and provide too much surface for malicious attacks while bearing immense workloads.

Together with our partners within the automotive industry, we identified 5 drivers of change that can help automotive companies secure their software:

1. Risk Mitigation

Cybersecurity needs to become as vital as the brakes. To mitigate risk, it is key to unfailingly detect edge cases and defend against the unknown.

2. ISO 21434 Compliance

Car manufacturers and OEMs will need to display Due Diligence when it comes to the security of their software and become ISO/SAE 21434 compliant.

3. Software Complexity

Traditional software testing approaches such as unit, static and dynamic application security testing cannot cope with interdependent software architecture and requirements.

Why is Fuzzing Especially Useful for Security Testing?

Here is a list of the features that make fuzz testing exceptionally useful for software security.

  • Fuzz testing is an almost completely automated testing technique. 
  • Fuzz testing can be used for both black- and white-box testing. 
  • Fuzz testing does not only discovers bugs but also provides you with a detailed report. 
  • Fuzz testing detects bugs reliably without false positives.

Success Story: Continental

Continental achieved to test a large safety module with 18,000 lines of code (LoC) within only one week.
 
The HMI Business Unit at Continental accelerated their development process and increased their test coverage by implementing continuous fuzz testing into their development process. Continental now achieves above 95% code coverage in almost all of their safety modules.
