Go (Golang) Application Security: A Practical Guide

In the modern world of web development, application security comes to the forefront. The Go language (Golang), with its built-in security mechanisms and high performance, is becoming increasingly popular for building critical systems. The book "Security of Go (Golang) Applications" is a comprehensive guide that will help you create secure, reliable, and attack-resistant applications in Go.

What is this book about?

The book covers the full security lifecycle of Go applications: from architecture design to production deployment. You will learn:

• Go Security Basics: memory management, typing, goroutines, and channels from a security perspective.
• Web Application Protection: preventing SQL injections, XSS, CSRF, SSRF, and other OWASP vulnerabilities.
• Secure Data Handling: encryption, password hashing, secrets management (Vault, env variables).
• Authentication and Authorization: JWT, OAuth2, OpenID Connect, RBAC, and ABAC in Go.
• API Security: protecting REST and gRPC services, rate limiting, input validation.
• Working with Databases: secure ORM queries, migrations, injection protection.
• Audit and Monitoring: security logging, tracing, SIEM integrations.
• DevSecOps for Go: SAST/DAST scanning, dependency analysis (Snyk, Trivy), secure CI/CD pipelines.

Who is this book for?

• Go Developers — from beginners to seniors, wanting to write secure code.
• DevOps and SRE Engineers responsible for deploying and operating Go services.
• Information Security Specialists studying application security in Go.
• Software Architects designing secure microservice systems.
• Team Leads and Tech Leads implementing secure development processes (SSDLC).

What will you learn?

After reading the book, you will be able to:

• Conduct code security analysis and find common vulnerabilities in Go applications.
• Implement protection against OWASP Top 10 in your projects.
• Configure secure data storage and transmission (TLS, mTLS, application-level encryption).
• Integrate security tools into the development process (CI/CD, static analysis).
• Develop secure microservices and APIs from scratch.
• Conduct security audits of existing Go applications.

The book contains many practical examples, ready-made code snippets, and checklists that can be immediately applied in your work. All examples are tested with current versions of Go (1.21+).

"Security of Go (Golang) Applications" is not just theory, but a practical guide that will help you protect your projects from real threats. Start writing secure code in
