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.

Session management mechanisms


Session managementinvolves the creation or definition of session identifiers on login, the setting of inactivity timeouts, session expiration, and session invalidation on logout; also, it may extend to authorization checks depending on the user's privileges, as the session ID must be linked to the user.

Sessions based on platform authentication

When platform authentication is used, the most common approach used is to work with the header that is already included, containing the credentials, or challenge the response as the identifier for a user's session, and to manage session expiration and logout through the application's logic; although, as stated previously, it's common to find that there is no session timeout, expiration, or logout when platform authentication is in place.

If Kerberos is used, the tokens emitted by the AS already include session information and are used to managing such session.
