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.

Chapter 3. Enumeration: Choosing Your Targets Wisely

To successfully penetrate a secured environment you must have a good understanding of what you are facing. The enumeration data gathered will assist in determining target prioritization. By the end of this chapter, you should be able to choose which targets are ideal candidates for your initial attacks. Certain attack types make more "noise" than others, thus a targeted attack will be less likely to be noticed. Thanks to the hard work of the open source community we have a large selection of tools available to help us enumerate networks. In this chapter, we will discuss the following:

  • How to add an additional computer to our virtual lab

  • Advanced Nmap scanning techniques

  • Adding custom Nmap scripts to your arsenal

  • Saving time with SNMP

  • Base lining your target networks with PBNJ

  • Avoiding enumeration attempts—confusing the enemy


Some examples in this chapter take advantage of firewalls and IDS logs to allow the reader to understand the impact...
