Go (Golang) Application Security: From Vulnerabilities to Protection

Developing in Go (Golang) is not only about speed and reliability, but also a huge responsibility for the security of your code. In the era of widespread use of microservices and cloud technologies, even a small vulnerability can lead to data leaks or complete system takeover. The book "Go (Golang) Application Security" is a practical guide that will teach you to think like a hacker in order to protect your code like a professional.

What this book is about

This is not just a reference guide to security functions. It is a deep, structured book that covers the full secure development lifecycle in Go:

• Go Security Basics: working with cryptographic libraries, safe memory management, and avoiding data races.
• Web Vulnerabilities: SQL injection, XSS, CSRF, SSRF, and other attacks common to Go web applications.
• API and Microservice Security: authentication and authorization (JWT, OAuth2), securing gRPC channels, secret management.
• Working with External Data: safe interaction with databases, Redis, queues, and third-party APIs.
• Network Security: protection against DoS/DDoS attacks, TLS/SSL configuration, secure HTTP server configurations.
• DevSecOps: integrating security into CI/CD pipelines, static analysis (SAST), dependency vulnerability scanning.

Who this book is for

This book will be useful for:

• Go developers of any level (from Junior to Senior) who want to write secure code from scratch.
• DevOps engineers responsible for deploying and securing Go services.
• Architects designing scalable and secure systems in Go.
• Students and beginner programmers who want to become in-demand specialists in the field of cybersecurity.

What you will learn

• How to find and fix common vulnerabilities in Go code (CWE, OWASP Top 10).
• How to properly implement encryption, hashing, and certificate management.
• How to protect your application from attacks at the network and application levels.
• How to integrate security checks into the development process.
• How to write secure tests and conduct code audits.

Each chapter contains real code examples, ready-to-use templates, and audit checklists. The book is written in accessible language, but does not sacrifice the depth of technical details. Make your Go applications invulnerable!
