Automotive Cybersecurity: Introduction & Fundamentals

In detail

Anyone working professionally with connected vehicles can't avoid this topic: modern cars today are more software than sheet metal, packed with control units, wireless interfaces, and cloud connections. That's exactly what makes them vulnerable. This book tackles automotive cybersecurity in its full breadth – from technical fundamentals through concrete attack vectors to the legal frameworks like UN R155 and ISO/SAE 21434, which are now mandatory for vehicle manufacturers and suppliers. For those coming from classic IT security who now need to get up to speed on the vehicle world, this book is a solid entry point: it explains why CAN bus, Ethernet backbones, and OTA updates bring their own distinct threat models, and how classic security concepts translate into this domain. Conversely, readers coming from automotive engineering get IT security fundamentals explained in an accessible way, without needing a computer science degree beforehand. Especially valuable is the look at the regulatory side. Since the UN R155 regulation on cybersecurity management systems took effect in the automotive industry, "it works" is no longer enough on its own – manufacturers must demonstrate that they manage risk systematically across the entire vehicle lifecycle. The book contextualizes these requirements and shows what they mean in practice for development, procurement, and operations. Content-wise, the book moves between theory and practical relevance: core concepts are introduced cleanly but are repeatedly mirrored against real vehicle architectures and known attack scenarios. That makes it accessible to students and career starters who want a well-founded overview before diving into specialized literature on individual sub-topics. Anyone working in the automotive industry, at suppliers, or in vehicle IT who wants to understand why cybersecurity has become just as much a mandatory part of the process as crash testing will find a solid, well-structured foundation here. This isn't a book for a quick skim – it's for readers who genuinely want to work through the subject.
