JavaScript (Node.js) Application Security

Modern web development with Node.js requires not only performance but also reliable protection against attacks. The book "JavaScript (Node.js) Application Security" is a practical guide that will help you create server-side and client-side JavaScript applications resistant to hacking.

The author systematically examines the most common threats from the OWASP Top 10 list as they apply to the Node.js ecosystem. You will learn how attackers exploit typical developer mistakes and how to prevent these attacks at the code writing stage.

What you will learn from the book:

• How to protect your application from Cross-Site Scripting (XSS) and CSRF attacks
• Methods for preventing SQL injections and NoSQL injections in MongoDB
• Secure authentication practices: JWT, sessions, OAuth 2.0
• Dependency management: identifying vulnerabilities in npm packages
• Protecting REST API and GraphQL endpoints
• Data encryption, secure storage of passwords and secrets
• Logging and monitoring security incidents

Who this book is for:

• Backend developers using Node.js who want to improve the security level of their projects
• Fullstack developers working with JavaScript and Express.js
• DevOps engineers responsible for deploying Node.js applications
• Students and beginner programmers learning web security

The book is written in clear language with numerous code examples. Each chapter contains practical exercises and checklists for security auditing. You will learn not only how to fix vulnerabilities but also how to design architecture with security requirements in mind from the very beginning of development.

This is a desktop reference that you will return to when creating each new project. Protect your users and your business — start writing secure code today.
