Advanced Penetration Testing for Highly-Secured Environments: The Ultimate Security Guide

By: Lee Allen

Overview of this book

The internet security field has grown by leaps and bounds over the last decade. Everyday more people around the globe gain access to the internet and not all of them with good intentions. The need for penetration testers has grown now that the security industryhas had time to mature. Simply running a vulnerability scanner is a thing of the past and is no longer an effective method of determining a business's true security posture. Learn effective penetration testing skills so that you can effectively meet and manage the rapidly changing security needs of your company. Advanced Penetration Testing for Highly-Secured Environments will teach you how to efficiently and effectively ensure the security posture of environments that have been secured using IDS/IPS, firewalls, network segmentation, hardened system configurations and more. The stages of a penetration test are clearly defined and addressed using step-by-step instructions that you can follow on your own virtual lab.The book follows the standard penetration testing stages from start to finish with step-by-step examples. The book thoroughly covers penetration test expectations, proper scoping and planning, as well as enumeration and footprinting. You'll learn how to clean up and compile proof of concept, exploit code from the web, advanced web application testing techniques, client side attacks, post exploitation strategies, detection avoidance methods, generation of well defined reports and metrics, and setting up a penetration testing virtual lab that mimics a secured environment. The book closes by issuing a challenge to your skills and ability to perform a full penetration test against a fictional corporation; followed by a detailed walk through of the solution.Advanced Penetration Testing for Highly-Secured Environments is packed with detailed examples that reinforce enumeration, exploitation, post-exploitation, reporting skills and more.

Introduction to fuzzing

Any time that an application allows for input, be it directly from the user such as when entering credentials, opening a file, or even from changing the data in RAM, there is a chance that the input can be used to cause havoc. Attackers will not spend hours, or days typing away (well, some might!) at a username and password prompt or an unknown connection to an obscure port. Instead, they will take advantage of tools that are focused on exactly this task—welcome to the world of fuzzers.

A fuzzer will typically be used to generate and output data; this data could be manipulated and formatted in various ways and there are published algorithms that assist in making the job even easier.


Keep in mind that input is a very broad term. When thinking about input vectors be sure to consider every method of input available to the application being tested. Something as seemingly trivial as streaming a song or even reading a filename could provide possible attack vectors.
