FAQs

  • What is automotive fuzz testing?

    Automotive fuzz testing is an automated software testing technique where random, unexpected, or invalid data is injected into automotive systems—such as ECUs or communication protocols—to uncover security vulnerabilities, bugs, and system weaknesses before they can be exploited in the real world. As vehicles become increasingly software-driven and connected, fuzz testing helps manufacturers identify and resolve issues that could compromise safety and cybersecurity

  • What types of vulnerabilities can automotive fuzz testing detect?

    Fuzz testing can reveal a range of security and reliability issues, including buffer overflows, injection attacks, memory leaks, crashes, hangs, and other failures that occur when systems are exposed to unexpected or malformed inputs. By identifying these issues early, fuzz testing helps improve the overall robustness and safety of automotive software

  • How does fuzz testing differ from other security testing methods like penetration testing?

    While penetration testing simulates real-world attacks to assess a system’s defenses, fuzz testing systematically bombards the system with a wide range of malformed or random inputs to expose unknown vulnerabilities and software bugs. Fuzz testing is often more automated and can cover a broader range of potential issues, complementing penetration testing by uncovering flaws that manual testing might miss

  • How does fuzz testing help with regulatory compliance in the automotive industry?

    Fuzz testing is increasingly recognized as a best practice for meeting automotive cybersecurity standards such as ISO/SAE 21434. While some regulations (like UN R155) do not mandate fuzz testing specifically, they require manufacturers to demonstrate robust risk assessment and mitigation processes, for which fuzz testing is a practical and effective approach

  • Does fuzz testing require deep cyber security skills?

    Some fuzz testing tools require users to define test scenarios from scratch, which assumes they have deep technical and cyber security skills. PlaxidityX Security AutoTester comes preloaded with over 200 test suites out-of-the-box, based on years of automotive cyber security research and domain expertise.
