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.

Identifying security objectives

A common way to analyze the security of a system is to evaluate if it has achieved its security objectives. These objectives can be grouped into five classes: integrity, authenticity, confidentiality, accountability, and availability. A typical automotive system will aim to achieve a subset of these objective classes. In the following subsections, we will explore each class of security objectives and give examples of how they apply to automotive systems.

Integrity

If you have worked in functional safety, then integrity is a familiar concept that ensures data is protected from corruption due to random or systematic faults in a system. In the context of cybersecurity, integrity has a more general meaning as it is concerned with protecting data not only from accidental corruption but also from malicious tampering. At a high level, a vehicle aims to protect the integrity of its data and safeguard its ability to correctly control its functions within...
