Web Penetration Testing with Kali Linux - Third Edition

By: Gilberto Najera-Gutierrez, Juned Ahmed Ansari

Overview of this book

Web Penetration Testing with Kali Linux - Third Edition shows you how to set up a lab, helps you understand the nature and mechanics of attacking websites, and explains classical attacks in great depth. This edition is heavily updated for the latest Kali Linux changes and the most recent attacks. Kali Linux shines when it comes to client-side attacks and fuzzing in particular. From the start of the book, you'll be given a thorough grounding in the concepts of hacking and penetration testing, and you'll see the tools used in Kali Linux that relate to web application hacking. You'll gain a deep understanding of classicalSQL, command-injection flaws, and the many ways to exploit these flaws. Web penetration testing also needs a general overview of client-side attacks, which is rounded out by a long discussion of scripting and input validation flaws. There is also an important chapter on cryptographic implementation flaws, where we discuss the most recent problems with cryptographic layers in the networking stack. The importance of these attacks cannot be overstated, and defending against them is relevant to most internet users and, of course, penetration testers. At the end of the book, you'll use an automated technique called fuzzing to identify flaws in a web application. Finally, you'll gain an understanding of web application vulnerabilities and the ways they can be exploited using the tools in Kali Linux.

Post-scanning actions

Sadly, it is more common than it should be that companies that offer penetration testing services end up doing only a vulnerability scan and customizing and adapting their reports without a manual testing phase, and without validating that the alleged vulnerabilities found by the scanner are actual vulnerabilities. Not only does this fail to provide any value to the customers, who by themselves could download a vulnerability scanner and run it against their applications, but it also damages the perception that companies have about security services and security companies, making it harder for those who provide quality services to position those services in the marketplace at competitive prices.

After a scanner generates the scanning report, you cannot just take that report and say that you found X and Y vulnerabilities. As scanners always produce false positives (that is, report vulnerabilities that don't exist) and false negatives (such as vulnerabilities missed by...
