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.

Preventing authentication and session attacks

Authentication in web applications is a difficult problem to solve, and no universal solution has been found to date. Because of this, preventing vulnerabilities in this area of applications is to a great extent case specific, and developers need to find a balance between usability and security according to the particular use cases and user profiles with which they are dealing.

We can say this even about session management, as current methods still represent workarounds of the deficiencies of the HTTP protocol. Probably with the advent of HTML5 and WebSockets or similar technologies, you will have some better alternatives to work with in the future.

Nevertheless, it is possible to define some generic guidelines for both authentication and session management, which would help developers raise the security bar to attackers, and we can use these as a reference when looking for defects and making recommendations to clients.
