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.

Securing diagnostic abilities

During development and maintenance, diagnostic and debug services are seen as lifesavers when it comes to identifying and troubleshooting vehicle issues. However, with this ability comes the risk of abuse. Diagnostic services in the hands of an attacker can pose serious risks to the vehicle data and control functions. This can cause unsafe actuation while the vehicle is in motion or tampering with diagnostic records or settings such as mileage manipulation or emission records tampering.

There are two strategies to protect the vehicle from the misuse of diagnostic services:

  • Disable diagnostic services where they are not needed: The first type of control entails accounting for all diagnostic service protocols and features in the vehicle. This includes ISO 14229 UDS-based diagnostics, XCP calibration and flashing, and any proprietary diagnostic routines that an ECU supplier may enable during development or manufacturing. Services that can be eliminated...
