Reverse Engineering Armv8-A Systems

Explore reverse engineering in Armv8-A-based Arm devices, develop the skills to analyze binaries, and leverage cutting-edge security hardening features through hands-on techniques and expert insights Key Features Master key aspects of Armv8-A, including register, exception handling, and TrustZone Build new reversing skills for kernel binaries, such as *.ko and vmlinux, for firmware analysis Understand Armv8-A's latest security features Purchase of the print or Kindle book includes a free PDF eBook Book DescriptionUnlock the secrets hidden in binary code without needing the source! Written by a Linux kernel engineer and author with over 14 years of industry experience, this book lays a solid foundation in reverse engineering and takes you from curious analyst to expert. You’ll master advanced techniques to dissect kernel binaries, including kernel module files, vmlinux, and vmcore, giving you the power to analyze systems at their core. This practical, three-part journey starts with the essentials of reverse engineering, introducing the key features of Armv8-A processors and the ELF file format. The second part walks you through the reverse-engineering process, from Arm environment setup to using static and dynamic analysis tools, including innovative methods for analyzing kernel binaries and the powerful debugging tool uftrace. The final part covers security, exploring TrustZone and the latest security techniques to safeguard Arm devices at the hardware level. By the end of this reverse engineering book, you'll have comprehensive Armv8-A expertise and the practical skills to analyze any binary with confidence while leveraging advanced security features to harden your systems.What you will learn Understand the organization of Arm assembly instructions Disassemble assembly code without using C code Work with reverse engineering tools, such as GDB and binary utility Apply reversing techniques for both user space and kernel binaries Get to grips with static and dynamic binary analysis processes Get a solid understanding of the powerful debugging tool, uftrace Analyze TrustZone and the advanced security features provided by Armv8-A Who this book is for This book is for professionals and enthusiasts interested in reverse engineering and debugging on Armv8-A-based devices. It is especially useful for system software engineers, security consultants, and ethical hackers expanding their binary analysis expertise. To get the most out of this book, you should have a basic understanding of the C programming language. Familiarity with computer architecture, Linux systems, and security concepts will be a definite advantage.

Systems: Theory and Practice

There is hardly a science that is without the notion of "system". We have systems in mathematics, formal systems in logic, systems in physics, electrical and mechanical engineering, architectural-, operating-, infonnation-, programming systems in computer science, management-and PJoduction systems in industrial applications, economical-, ecological-, biological systems, and many more. In many of these disciplines formal tools for system specification, construction, verification, have been developed as well as mathematical concepts for system modeling and system simulation. Thus it is quite natural to expect that systems theory as an interdisciplinary and well established science offering general concepts and methods for a wide variety of applications is a subject in its own right in academic education. However, as can be seen from the literature and from the curricula of university studies -at least in Central Europe-, it is subordinated and either seen as part of mathematics with the risk that mathematicians, who may not be familiar with applications, define it in their own way, or it is treated separately within each application field focusing on only those aspects which are thought to be needed in the particular application. This often results in uneconomical re-inventing and re-naming of concepts and methods within one field, while the same concepts and methods are already well introduced and practiced in other fields. The fundamentals on general systems theory were developed several decades ago. We note the pioneering work of M. A. Arbib, R. E. Kalman, G. 1. Klir, M. D.
