Get started becoming an automotive cybersecurity professional. With this book.

Based on our expertise in automotive cybersecurity consulting, we see: There is an enormous need for knowledge to fully understand the requirements of automotive cybersecurity. In order to be able to start immediately with the implementation in practice, help is needed.

ISO/SAE 21434 Road Vehicles – Cybersecurity Engineering, which was officially published end of August 2021 (Read more: ISO/SAE 21434:2021 is now officially published), is the starting point. For OEMs and Tier-N suppliers, the standard provides the basis for a systematic approach to cybersecurity in the automotive industry: at the organizational level, for development projects, for cross-organizational collaboration, for engineering processes, and for individual roles.

The Essential Guide to ISO/SAE 21434 is the world’s first officially licensed reference book on ISO/SAE 21434:

  • Get an overview of the requirements and work products of the ISO/SAE 21434 (and beyond)
  • Understand the correlations between all dimensions and interdependencies of automotive cybersecurity
  • Have a more in-depth grasp of specific methods and approaches around cybersecurity

This book does so with a strong focus on comprehensibility and a high level of practical relevance. Get a first overview with the Table of Contents:

For automotive cybersecurity beginners

For more and more automotive specialists, cybersecurity is becoming a new topic on the agenda. For this, our book is the best possible introduction: Learn about all dimensions and dependencies of automotive cybersecurity to be able to shape the practice of cybersecurity

(e.g. functional safety experts entering cybersecurity).

In-depth understanding of automotive cybersecurity

This book is also a valuable resource for anyone who has only been familiar with the topic of automotive cybersecurity on a limited basis and is currently in the process of gaining a broader overall view

(e.g. project managers who are in the topic at the coordination level but are not yet fully familiar with all disciplines).

For those who are responsible for compliance

For decision makers who have the responsibility to establish applied automotive cybersecurity in the organization in order to comply with the applicable standards and regulations, this book offers a unique opportunity to grasp the big picture

(e.g. for new cybersecurity manager positions that need to ensure compliance to the standards).

How to manage the challenges of the new automotive cybersecurity regulations?

Cybersecurity is a new topic for the automotive industry. The relevant standards and regulations (such as ISO/SAE 21434 or UN Regulations No. 155 / 156) are only now being published, but at the same time they must be applied immediately. This makes it all the more important to establish a comprehensive and holistic understanding of automotive cybersecurity quickly and efficiently. This book is designed to fulfill this requirement.

  • Automotive cybersecurity best practices and practical examples to make things more tangible: At all possible points, concrete examples clarify what is meant and what the application might look like
  • High-quality illustration: There are over 100 high-quality illustrations and visualizations in all chapters
  • Extensive background information: In addition to ISO/SAE 21434, for example, other relevant standards and regulations are also considered
  • Highlighted key takeaways: Unlike academic textbooks, this book highlights important information throughout the text
