Angular and Node Security: Building Authentication from Scratch

Security is a critical pillar of modern software development, yet many developers struggle to implement it correctly from scratch. Building robust authentication and authorization is essential for protecting user data and advancing your software development career. In this course, you will learn the core fundamentals of web application security by building secure systems step-by-step. Using the popular Angular and Node.js stack, you will explore how to handle user credentials, manage sessions, and restrict access to resources. By reading through conceptual breakdowns and analyzing secure code implementations, you will develop the skills needed to design, implement, and audit security features in modern web applications. What you'll learn: - Understand core web security principles, including authentication, authorization, and session management. - Implement secure token-based authentication using JSON Web Tokens (JWT) in Node.js and Angular. - Configure route guards and HTTP interceptors in Angular to protect client-side resources. - Apply defensive coding practices to protect against common vulnerabilities like XSS, CSRF, and injection attacks. - Design robust role-based access control (RBAC) systems to manage user permissions. - Practice implementing secure cookie strategies, including HttpOnly and SameSite attributes, for enhanced token storage. The course starts with foundational security terminology and the basics of user identity. From there, you will progress through server-side implementation in Node.js, client-side integration in Angular, and advanced defensive techniques to harden your entire application. This course is designed for beginner to intermediate developers who want to understand web security. No prior security experience is required, though a basic understanding of Angular and Node.js will help you get the most out of the written examples.
