Embedded systems are no longer isolated devices. They are connected, updateable, and often expected to run for many years without being replaced. In this context, security cannot be treated as an add-on. It has to be part of the system design.

This book focuses on security architecture for modern embedded systems. It does not catalog vulnerabilities or tools. Instead, it takes a design-first approach, showing how security emerges from architectural decisions: how trust is established, how firmware is verified, how keys are stored, how updates are performed, and how these mechanisms are designed to work together in real products.

The perspective is practical and constraint-driven. Embedded systems have limited resources, long lifetimes, and are often physically accessible to attackers. Many devices cannot be patched frequently, if at all. These realities shape how security mechanisms must be designed and integrated in practice, rather than how they are described in theory.

The book is intended for embedded engineers, system architects, and technical leads who design real products. Topics include secure coding, secure boot and root-of-trust design, firmware integrity, credential handling, update mechanisms, attack-surface considerations, and common architectural trade-offs encountered in real-world embedded systems.

This is a living book and will be updated over time. It is not an exploit-development or offensive security guide. The goal is to help readers design embedded systems whose security holds up over their entire operational lifetime, not just at first deployment.
