Welcome to the "Introduction to Web Security Essentials" project! In this repository, you will explore the fundamentals of web security, including common vulnerabilities and best practices to safeguard web applications. Understanding how to protect your web applications from malicious attacks is crucial for developers, system administrators, and anyone involved in web development.

• Injection Attacks: Learn about injection attacks, including SQL Injection and other injection vulnerabilities, how they work, and ways to prevent them.
• Broken Access Control: Understand how attackers exploit broken access control mechanisms and how to implement proper access control techniques to secure your applications.
• Broken Authentication: Learn about common authentication vulnerabilities, such as weak login systems and password management flaws, and how to mitigate them to ensure secure user authentication.
• Server-Side Request Forgery (SSRF): Understand SSRF attacks, where attackers can send unauthorized requests from the server, and learn how to prevent them.
• Web Security Best Practices: Explore techniques to ensure the security of your web applications, including input validation, HTTPS, and more.

Web security is a critical aspect of modern web development. With more and more sensitive data being shared and stored online, it is crucial to protect your applications from malicious threats. Hackers are constantly looking for vulnerabilities, and even small mistakes can lead to significant security breaches.

This project provides a practical introduction to securing your web applications. By following the lessons in this repository, you’ll gain a solid understanding of web security concepts and how to apply them.

To get started with the examples in this repository, you will need:

• just a computer

1. Clone the repository to your local machine:

   git clone https://github.com/aayush256-sys/Vulearn.git

2. Set up the provided sample web applications to see how vulnerabilities like XSS and SQL Injection can be exploited and mitigated.

   Frontend build

   cd client && npm i

   npm run dev

   Backend build

   cd server && npm i

   npm run dev

   **Note: For database sql and nosql injection u can use a mongodb for nosql and psql for sql injection.

Here’s a screenshot of the web page demonstrating some of the web security concepts covered in this project:
