C++ Application Security: Protecting Code from Vulnerabilities and Attacks

Modern C++ applications work with critical data: from bank transactions to medical records. However, the power and flexibility of C++ make it particularly vulnerable to memory attacks, buffer overflows, and other low-level vulnerabilities. The book "C++ Application Security" is not just a list of vulnerabilities, but a full-fledged practical guide to creating secure code from scratch.

Who is this book for?

• C++ developers (from Junior to Senior) who want to write code resistant to hacking.
• DevOps and system engineers responsible for build and deployment security.
• Pentesters and information security specialists studying vulnerabilities at the compiler and runtime level.
• Students studying system programming and security.

What will you learn from the book?

• How classic C++ vulnerabilities work: buffer overflow, use-after-free, double-free, race conditions.
• How to use static analyzers (Clang Static Analyzer, PVS-Studio) and dynamic analyzers (Valgrind, AddressSanitizer) to find errors.
• Best practices for safe use of pointers, smart pointers (std::unique_ptr, std::shared_ptr), and STL containers.
• Implementing data encryption using OpenSSL and Crypto++ in C++ projects.
• How to protect against input-based attacks: SQL injection, XSS, command injection in the context of C++.
• Secure network programming: protection against traffic interception, TLS/SSL, preventing DoS attacks.
• Modern protection methods: ASLR, DEP, CFG (Control Flow Guard), SafeSEH.
• Organizing a secure development lifecycle (SDL) for C++ teams.

Book features:

• All code examples compile under GCC, Clang, and MSVC.
• Ready-made checklists for code audit and security policy templates.
• Analysis of real CVE (Common Vulnerabilities and Exposures) in popular C++ libraries.
• A chapter on safe multithreading: mutexes, atomic operations, avoiding deadlocks.

This book will help you not only find and fix vulnerabilities but also design architecture so that many classes of attacks are impossible at the design level. You will learn to think like an attacker to protect your code.

Brief summary: Memory security basics → Pointer and container vulnerabilities → Safe file and network operations → Cryptography in C++ → Static and dynamic analysis → Exploit protection → SDL and code audit.

The book is suitable for self-study and as a reference for daily work. Start writing secure C++ code today!
