Welcome to the very first lesson of the "OWASP Top 10 & Common Attack Vectors with TypeScript (1-5)" path! 🌟 In this introductory lesson, we will embark on a journey to understand the significance of web application security and how to protect our applications from common security vulnerabilities.

Through practical, real-world examples, you'll learn how to:

• Implement proper access control mechanisms to prevent unauthorized access to sensitive data
• Protect your applications from various injection attacks, including SQL injection
• Set up robust cryptographic systems to secure sensitive information
• Design secure applications from the ground up
• Configure security settings correctly to minimize vulnerabilities

Let's take a closer look at how we'll achieve these learning objectives through our carefully structured course format.

The OWASP (Open Web Application Security Project) is a nonprofit foundation that works to improve software security through its continuously updated knowledge base of security risks and best practices, with the OWASP Top 10 being its flagship awareness document. This course is the first in a two-part series, where each course focuses on five critical web application security risks from the 2021 OWASP Top 10.

This course is designed with a practice-first approach, where each vulnerability is explored through real-world scenarios and hands-on exercises. You'll work with practical examples that demonstrate:

1. How attackers exploit these vulnerabilities in real applications
2. Common attack vectors and techniques used in the wild
3. Best practices for preventing and mitigating these security risks
4. Practical implementation of security measures using TypeScript

To help you apply these concepts effectively, we've prepared a comprehensive learning environment with real-world applications.

Before moving on to the next unit, there will be a practice section where you'll have the opportunity to get acquainted with a dummy pastebin-app project. This project will be used throughout the course to demonstrate examples in the lessons. While we'll use this project for hands-on practice, keep in mind that the goal is to help you understand security concepts at a broader level so you can identify and mitigate these issues in any real-world application.

In the next unit, we'll dive into our first vulnerability: Broken Access Control. You'll learn how seemingly minor oversights in access control can lead to serious security breaches, and how to implement robust protection mechanisms in your applications.

Get ready to explore real-world scenarios and build more secure applications! 🚀
