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.

Common ECU threats

When looking at threats against external vehicle interfaces, we indirectly analyzed threats that impact external facing ECUs, such as telematics, IVI, and autonomous driving systems. In this section, we will expand our focus on threats that apply to both internal and external facing ECUs, based on the most common weaknesses of these systems.

Debug ports

ECUs offer several methods to access debug capability during development and, in some cases, after the ECU has been installed on a production vehicle. The JTAG interface is commonly used to debug and test the internal operation of an ECU. Attackers who gain access to the JTAG interface can extract the ECU software for offline analysis to identify vulnerabilities that can be exploited in the field. Another popular attack is attempting to recover global secrets, such as long-term cryptographic keys that are accessible in a debug mode. In addition to these attacks, ECU suppliers may have proprietary test modes...
