Book Description

As embedded Linux systems power countless devices in our daily lives, they’ve become prime targets for cyberattacks. In this in-depth guide to safeguarding your Linux devices, the author leverages his 30+ years of technology experience to help you mitigate the risks associated with hardware and software vulnerabilities.

This book introduces you to the world of embedded systems, the brains behind your everyday appliances. It takes you through the different types of embedded systems, their uses, and the platforms they run on, while addressing their unique security challenges and support considerations. You’ll learn how to build a successful, secure, and user-friendly solution by exploring the critical hardware and software components that form the foundation of a secure appliance. We won't forget the human element either; you'll find out how to configure your system to prevent user errors and maintain its integrity. The book lets you put your newfound knowledge into action, guiding you through designing a robust build chain that supports the entire life cycle of your appliance solution, enabling seamless updates without your direct involvement.

By the end of this book, you’ll be able to adapt your appliance to the ever-evolving threat landscape, ensuring its continued security and functionality in real-world conditions.

What you will learn

• Understand how to determine the optimal hardware platform based on design criteria
• Recognize the importance of security by design in embedded systems
• Implement advanced security measures such as TPM, LUKS encryption, and Secure Boot processes
• Discover best practices for secure life cycle management, including appliance update and upgrade mechanisms
• Create a secure software supply chain efficiently
• Implement childproofing by controlling access and resources on the appliance
