Website Penetration Testing - Certificate

In an increasingly interconnected world, web applications have become a cornerstone of modern business operations. From e-commerce platforms to social networking sites, these dynamic and interactive interfaces allow users to access information, conduct transactions, and communicate seamlessly. However, the convenience and efficiency of web applications come hand in hand with potential vulnerabilities that can be exploited by malicious actors. This is where web app penetration testing comes into play.
Web application penetration testing is a systematic process of evaluating the security of web applications by simulating real-world attacks. The primary objective is to uncover vulnerabilities, weaknesses, and potential entry points that could be exploited by attackers to compromise the confidentiality, integrity, or availability of the application and its underlying data.
This comprehensive web application penetration testing tutorial aims to provide an in-depth exploration, equipping both aspiring security professionals with the knowledge and skills necessary to identify and mitigate vulnerabilities within web applications. Through a structured and methodical approach, this tutorial on web app pentesting will guide you through various stages, enabling you to assess the security posture of web applications effectively.

Cross Origin Resource Sharing (CORS) Definition

Testing for CORS Vulnerability

Test your knowledge with a quick quiz!

<a href="https://developer.mozilla.org/en-US/docs/Web/HTTP/CORS" target="_blank" rel="noopener">CORS</a> stands for Cross-origin resource sharing. It is a web-based mechanism that is used to control access to resources hosted outside a specific domain. It has several benefits, like getting the flexibility for addition and extension of the same-origin policy (SOP).

To test cross-origin resource sharing (CORS), you can use tools like <a href="https://owasp.org/www-project-zap/" target="_blank" rel="noopener">OWASP Zed Attack Proxy</a> Project. It will help you to intercept HTTP headers. You need to pay heed to the origin header to understand the domains that are allowed.&nbsp;
Moreover, you can further inspect it with JavaScript, the manual way to check if the code is vulnerable to code injection as a result of not handling the input properly.&nbsp;
