ISO/SAE 21434 Compliance: Ensuring Automotive Cybersecurity with TrustInSoft

ISO 21434 aims to ensure the cybersecurity of road vehicles throughout their entire lifecycle, from design to decommissioning, protecting them from cyber threats.

Key components include security management, continuous cybersecurity activities, risk assessment methods, and integrating cybersecurity into product development and post-development stages.

Non-compliance can lead to cyberattacks, safety hazards, reputational damage, and potential regulatory penalties.

TrustInSoft Analyzer provides mathematically proven memory safety, eliminates vulnerabilities, facilitates risk assessment, and generates compliance reports, streamlining the compliance process.

The tool is qualified for ISO 26262, which means it is ideally suited to provide the proof of cybersecurity needed for ISO/SAE 21434 compliance.

It can emulate embedded hardware platforms, allowing it to analyze software in the exact configuration in which it will run, helping to find vulnerabilities that unit testing in a host environment might miss.

At TrustInSoft, we believe the best practice for implementing ISO/SAE 21434 is a secure-by-design approach. Instead of trying to bolt on security at the end, you should integrate it from the very start of a project.

TrustInSoft Analyzer, helps by finding and eliminating dangerous undefined behaviors early, before they become serious vulnerabilities.

A critical part of this process is achieving provable security. Traditional methods like testing and static analysis are prone to false negatives, meaning they can miss subtle, critical bugs. Our unique use of formal verification provides a mathematical proof that your C/C++/Rust code is free of certain vulnerabilities like buffer overflows. This level of certainty is far superior to what conventional testing can offer.

Finally, you need to ensure end-to-end traceability and robust documentation. Our tool helps by generating auditable evidence that your code is free from an entire class of vulnerabilities. This mathematical proof simplifies the compliance process and gives you the confidence to demonstrate security to regulators and customers.

TrustInSoft Analyzer integrates into existing development workflows to provide a proactive, shift-left security strategy for ISO 21434 compliance.

Instead of being a separate, late-stage check, TrustInSoft Analyzer fits seamlessly into your Continuous Integration/Continuous Development (CI/CD) pipelines. This allows for automated analysis with every code commit, giving developers immediate feedback and helping them fix vulnerabilities in minutes. It can also be used directly on developer workstations, empowering teams to identify and resolve issues before they even enter the main codebase.

Unlike traditional tools that can miss bugs, it guarantees the absence of critical vulnerabilities like buffer overflows. This eliminates false negatives and provides a level of definitive assurance required by the standard.

This provable security simplifies the entire compliance process. TrustInSoft Analyzer generates the necessary auditable evidence, serving as a key component of your cybersecurity case. By integrating it into your workflow, you save time, reduce costs, and gain the confidence that your software is truly secure.

You don't get certified to ISO 21434; instead, you demonstrate compliance by following its processes. TrustInSoft Analyzer helps you achieve this by providing the necessary evidence.

The steps are:

1. Integrate TrustInSoft Analyzer: Embed the tool into your CI/CD pipeline or development workflow from the start. This aligns with the standard’s secure-by-design principle.
2. Conduct Continuous Analysis: Use TrustInSoft Analyzer to perform continuous, mathematically sound analysis on your C/C++ code. This proactively identifies and eliminates security vulnerabilities, such as undefined behaviors, early in development.
3. Generate Evidence for Compliance: The tool produces a mathematical proof that an entire class of vulnerabilities is absent. This verifiable evidence is crucial for your Cybersecurity Case, a key requirement of ISO 21434.

By following these steps, you move beyond simple testing to provide definitive, verifiable proof of your software's security, significantly streamlining the process of demonstrating ISO 21434 compliance to auditors and partners.

Automated code analysis is crucial for implementing ISO 21434 by shifting security left in the development lifecycle. Instead of finding bugs late in testing, automated tools identify vulnerabilities early and continuously.

Proactive Vulnerability Detection: Tools can automatically scan code for common weaknesses like buffer overflows and memory leaks, which are significant cybersecurity risks addressed by the standard. This proactive approach helps reduce the number of bugs before they can be exploited.

Streamlined Compliance: Automated analysis provides traceable evidence that your software adheres to secure coding standards (like CERT C) and helps you document risk mitigation efforts. This verifiable evidence is essential for the cybersecurity case required by ISO 21434.

Efficiency: By integrating into CI/CD pipelines, automated tools provide rapid, repeatable feedback. This reduces the time and cost associated with manual code reviews and late-stage bug fixes, helping you achieve compliance more efficiently.

TrustInSoft Analyzer helps detect and eliminate software vulnerabilities by providing mathematical proof of code correctness, directly addressing key requirements of ISO 21434.

Traditional methods like static analysis and fuzz testing are prone to false negatives, meaning they can miss subtle, critical vulnerabilities. TrustInSoft Analyzer, on the other hand, uses formal verification to perform an exhaustive analysis of all possible execution paths. This process mathematically proves the absence of an entire class of dangerous undefined behaviors, such as buffer overflows, memory leaks, and use-after-free errors.

This approach provides a higher level of assurance than traditional testing, as it guarantees that a vulnerability does not exist. The resulting proof serves as auditable evidence for your Cybersecurity Case, streamlining compliance and reducing the time and cost associated with manual security reviews. By providing definitive proof of security, TrustInSoft Analyzer enables a more efficient and effective path to meeting the rigorous demands of ISO 21434.

Unlike traditional testing that can only show the presence of bugs, TrustInSoft Analyzer guarantees the absence of an entire class of critical vulnerabilities like buffer overflows. This definitive evidence is crucial for satisfying the rigorous verification and validation requirements of the standard.

It boosts efficiency and traceability. By integrating into your development workflow, it proactively identifies and helps eliminate bugs early, reducing the time and cost of manual reviews and late-stage fixes. TrustInSoft Analyzer's analysis generates detailed, auditable reports that serve as a core component of your Cybersecurity Case, simplifying documentation for auditors and partners.

It provides a high level of assurance by eliminating false negatives. Because of its formal verification approach, you can be confident that no critical vulnerabilities have been missed, a level of certainty that is essential for building safe and secure automotive systems.

TrustInSoft provides mathematical proof of software reliability for ISO 21434 through its use of formal verification, which is a more rigorous method than traditional testing.

Instead of running a program on a limited number of inputs, TrustInSoft Analyzer uses a technique called abstract interpretation. This method mathematically explores all possible execution paths of the C/C++ code. By doing this, it can definitively prove the absence of an entire class of critical vulnerabilities, such as buffer overflows, memory leaks, and use-after-free errors.

This mathematical proof is crucial for ISO 21434 because it offers a level of certainty that simple testing can't provide. It eliminates false negatives, guaranteeing that a vulnerability does not exist. This verifiable evidence is a key part of the required Cybersecurity Case, streamlining the compliance process and demonstrating a higher level of assurance to auditors and stakeholders.
