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.

Launching attacks internally can be both satisfying and rewarding. You will no longer be restricted by the protected outer shell of the network and can traverse at will. Be careful that the tools used do not give you away.


By understanding what an administrator would see under certain conditions a penetration tester is more likely to perform well thought-out work that is in line with the final goal of the test as described in the rules of engagement contract.

Here we have a connection from a BackTrack machine to a Kioptrix level 1 machine. Take a look at the strange traffic being logged by the firewall:

Now if we were to quickly log into the system and set up or escalate privilege of a user account to allow us SSH capability we could merge with the existing traffic on the network. Let's take a look at the difference when we are logged into SSH now while running the tree command in the SSH session:

bash-2.05# tree | head
|-- X11R6
|   |-- bin
|   |   |-- fslsfonts
