Rust Application Security: From Beginner to Expert

The book "Rust Application Security" is a comprehensive guide that will help you master all aspects of writing safe and reliable code in Rust. Unlike many other languages, Rust provides unique capabilities for preventing entire classes of errors at the compilation stage, but even in such a safe language there are nuances and pitfalls. This book reveals them all.

Who is this book for?

• For beginner Rust developers who want to write secure code from the very first steps.
• For experienced Rust programmers who want to deepen their knowledge in security and performance.
• For developers transitioning from C/C++ who value strict memory control.
• For anyone interested in systems programming and wanting to avoid common vulnerabilities.

What you will learn from the book:

• How the ownership and borrowing system works and how it prevents memory leaks and data races.
• Detailed analysis of unsafe code: when it is necessary, how to use it with minimal risk, and how to test it.
• Protection against common vulnerabilities: buffer overflow, use-after-free, null pointer dereference, and others.
• Safe work with external FFI calls and integration with C libraries.
• Practical examples of safe multithreading and asynchronous programming.
• Static analysis and fuzzing tools for finding hidden bugs.
• Best practices for writing cryptographic code and working with confidential data.

The book is structured on the principle "from simple to complex." In the first chapters, you will refresh the basics of security in Rust, and then move on to deep topics such as creating safe abstractions and developing secure protocols. Each chapter contains practical examples ready for use in real projects and exercises to reinforce the material.

Special attention is paid to real-world scenarios: how to protect an Actix web server from attacks, how to safely handle user input, how to avoid data races in high-load systems. You will learn not just to write code, but to think like a security engineer, anticipating potential problems.

After reading this book, you will be able to confidently develop system software, web applications, and libraries in Rust that are resistant to most known attacks and errors. This is not just a book about syntax — it is a guide to creating reliable software that will stand the test of time.

Note: The book is intended for readers already familiar with the basics of Rust syntax. If you are just starting out, we recommend first completing an introductory course.
