By now, you should have mastered all the aspects of securing your web applications. In this chapter, we have learned about active and passive data gathering of your web application and the best tools and methods used to discover sensitive data about your web application on the internet. We also learned about the risk of not obfuscating some public information about your web application.

We also learned how to install, configure, and use the best virtual environment to become familiar with the most common vulnerabilities on web applications (the DVWA platform). Additionally, we explored how to install, configure, and use the best tool to assess the security of a given web application in real time (Burp Suite).

And we also experienced a real hands-on example to see how easily an attacker can take advantage of common vulnerabilities to exploit your web application.

But there are many other tools to find vulnerabilities in your web application and even the entire infrastructure...
