Learning Security Basics with Typescript

This course explores the importance of input validation and its role in web application security. Using TypeScript and Express.js, we will analyze client-side and server-side validation, common bypass techniques, and secure coding practices. The course follows an **offense-defense approach**, where we first explore vulnerabilities before implementing security solutions.

This course covers the fundamental principles of **session management security** in web applications. You will learn how sessions work, their role in authentication, and the risks of improper session handling. The course follows an **offense-defense approach**, demonstrating common session attacks before implementing secure solutions.

This course provides a deep dive into **authentication and authorization** mechanisms in modern web applications. You will learn how to securely store passwords, implement role-based access control (RBAC), and protect against authentication attacks. The course follows an **offense-defense approach**, exposing vulnerabilities before applying secure coding practices.
