Overview of this book

Replete with exciting challenges, automotive cybersecurity is an emerging domain, and cybersecurity is a foundational enabler for current and future connected vehicle features. This book addresses the severe talent shortage faced by the industry in meeting the demand for building cyber-resilient systems by consolidating practical topics on securing automotive systems to help automotive engineers gain a competitive edge. The book begins by exploring present and future automotive vehicle architectures, along with relevant threats and the skills essential to addressing them. You’ll then explore cybersecurity engineering methods, focusing on compliance with existing automotive standards while making the process advantageous. The chapters are designed in a way to help you with both the theory and practice of building secure systems while considering the cost, time, and resource limitations of automotive engineering. The concluding chapters take a practical approach to threat modeling automotive systems and teach you how to implement security controls across different vehicle architecture layers. By the end of this book, you'll have learned effective methods of handling cybersecurity risks in any automotive product, from single libraries to entire vehicle architectures.

Secure coding practices versus safe coding techniques

Similar to the design principles, coding guidelines between safety and security have a high degree of correlation. Both safety and security engineering approaches aim to reduce code complexity to prevent defects and vulnerabilities. They both require the usage of language subsets to avoid risky features of the programming language that can introduce unexpected or unwanted behavior. This can be enforced by using static code analysis tools based on MISRA C, CERT C/C++, and AUTOSAR C++. Normally, the toolchains support the safety and security guidelines, allowing the developers to check for all coding rule violations in a single run. When it comes to defensive coding techniques, there is a high degree of overlap between several such techniques:

  • Input validation requires all inputs from external sources to be validated to ensure they conform to the expected formats, ranges, and data types. This can help prevent working on implausible...
