Web Penetration Testing with Kali Linux

Overview of this book

Kali Linux is built for professional penetration testing and security auditing. It is the next-generation of BackTrack, the most popular open-source penetration toolkit in the world. Readers will learn how to think like real attackers, exploit systems, and expose vulnerabilities. Even though web applications are developed in a very secure environment and have an intrusion detection system and firewall in place to detect and prevent any malicious activity, open ports are a pre-requisite for conducting online business. These ports serve as an open door for attackers to attack these applications. As a result, penetration testing becomes essential to test the integrity of web-applications. Web Penetration Testing with Kali Linux is a hands-on guide that will give you step-by-step methods on finding vulnerabilities and exploiting web applications. "Web Penetration Testing with Kali Linux" looks at the aspects of web penetration testing from the mind of an attacker. It provides real-world, practical step-by-step instructions on how to perform web penetration testing exercises. You will learn how to use network reconnaissance to pick your targets and gather information. Then, you will use server-side attacks to expose vulnerabilities in web servers and their applications. Client attacks will exploit the way end users use web applications and their workstations. You will also learn how to use open source tools to write reports and get tips on how to sell penetration tests and look out for common pitfalls. On the completion of this book, you will have the skills needed to use Kali Linux for web penetration tests and expose vulnerabilities on web applications and clients that access them.

Clickjacking defense


Clickjacking was covered in Chapter 5, Attacking Authentication, and is the technique where an attacker tricks a user into clicking on something other than what they believe they are clicking on. One of the best ways to protect against clickjacking is by running the noscript extension for Firefox or Chrome browsers. This will prevent unauthorized code from running in your web browser. Noscript can detect unauthorized scripts, alert the user of the script and prevent the script from running. Users have the ability to turn off scripting controls globally per session or per website.

The authors of this book are big fans of noscript; however, you should encourage web developers to set up X-Frame-Options header in HTTP responses to mitigate this risk in web applications. Furthermore, some application delivery controller appliances (ADCs), give administrators the option of writing custom scripts that can also help mitigate this risk.
