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.

Passwords: Something you know…

In this day and age one would assume that all systems use multifactor authentication. Unfortunately that is not the case. Even so-called "secured networks" still use protocols that are sending out clear text passwords, systems are using insecure encryption protocols, and more. One basic skill (basic as in chess: easy to learn, difficult to master) that every pentester should attempt to master is the art of password cracking. We will start off with a few simple examples to solidify the concept and then move on to some of the strategies used by the very best in the field.

Cracking the hash

Passwords are often reused by busy users and even administrators. Regardless of how important a system is on the network, once you gain access to the password hashes they should immediately be cracked and added to any dictionary file you have in place. This could potentially save a lot of time.

First we need to pull some files from the victim machine. Start up your BackTrack Tester...
