Why comply with ISO/SAE 21434

ISO/SAE 21434 'Road vehicles — Cybersecurity engineering' specifically recommends fuzz testing for cybersecurity validation and verification during product development.

Automotive software security

Automakers prioritize visible issues over application security. Short-term gains but long-term risks; ISO 21434 demands software security, signaling change.


Hacking a Jeep is surprisingly easy

Connectivity in modern vehicles exposes them to remote hacks. A 2015 incident with a Jeep Cherokee shows the grave risks - 1.4 million recalls, massive financial damage.


Be reliable and secure

Vulnerabilities in automotive software pose wide-reaching consequences. Swift digitization created an imbalance in software security, risking public safety. Proactive action is crucial.

How fuzz testing helps to comply with regulations

Discover how the Volkswagen group's CARIAD leverages fuzz testing to comply with ISO 21434 and secure the code early in the development.

Goals of ISO 21434.

ISO 21434 will be implemented with several goals in mind. These are the most important ones:
Cheat Sheet Screanshot
  • Creating a standardized terminology for software security within the automotive landscape
  • Defining minimal requirements for software security engineering
  • Improving collaboration within the automotive value chain
  • Becoming the new security benchmark
  • Incorporating security early on in the development lifecycle
  • Establishing a security culture

3 steps that will help you to develop secure automotive software.



Foster a security culture.

Cultural acceptance is key for secure software. Automotive companies must cultivate a culture where everyone in the SDLC prioritizes security, supported by management and developers. Tooling, values, and practices must align.

Shift left.

Testing post-release is too late for automotive software security. “Shifting left” with early testing in the SDLC is crucial, outweighing late-stage bug fixes or recalls.





Use feedback-based fuzzing in automotive software.

Common automotive security tests (SAST, DAST) have drawbacks. Feedback-based fuzzing, like CI Fuzz, offers efficiency by automating and minimizing false positives, ideal for automotive software.

Build secure automotive software.

Automotive companies need to make software security a priority and implement appropriate security measures before it is too late. This will not only make our roads safer, but also save time, money, and nerves. DevSecOps and automotive fuzzing tools offer great solutions that manufacturers can implement to prevent crashes, and thus improve the efficiency and accuracy of their testing efforts while minimizing costs.
