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.

Exploring BackTrack

Congratulations, you now have one of the most powerful collections of penetration tools available and ready for your usage. Entire books are dedicated to covering the excellent collection of tools that are part of the BackTrack Linux platform. This toolkit will definitely save you a lot of time out in the field.

Logging in

Your login information for the default install is:

bt login: root
bt password: toor

Changing the default password

After logging in, we should change this default password as soon as possible. You can do this by typing passwd at the prompt and replacing 1NewPassWordHere as seen in the example with your own secure password.

root@bt:~# passwd
Enter new UNIX password: 1NewPassWordHere!
Retype new UNIX password: 1NewPassWordHere!
passwd: password updated successfully


If you are having issues with screen resolution or experiencing other minor annoyances, you may want to install the VirtualBox Guest Additions. With the guest machine running, click on Devices and then Install Guest Additions to initiate this install. You will be required to restart BackTrack afterwards.

Updating the applications and operating system

Your virtual machine network cards are currently configured to allow your BackTrack installation to access your host system's Internet connection using NAT. In order to update the operating system there are a few commands that you should become familiar with.


If you do not have an Internet connection the system will not be able to update.

One thing to keep in mind is that BackTrack is based on Ubuntu and as with any other operating system, patching is required in order to ensure that the latest security patches are applied. It is also important to keep applications up-to-date so that the latest testing techniques and tools can be taken advantage of!

By default, BackTrack is set up to use only the BackTrack repositories. If curious, you can see what these are by looking at the /etc/apt/sources.list file.

The first command that will need to be initialized is the advanced packaging tools (APT) update function. This will synchronize the package index files to ensure that you have information about the latest packages available. The update functionality should always be used prior to installing any software or updating your installed packages.

# apt-get update

After this update is complete you may initialize apt's upgrade command. All installed packages will be updated to the latest release found within your repositories.

# apt-get upgrade

There is another apt command that is used to update your system. dist-upgrade will bring BackTrack to the latest release. For example, if you are running BackTrack 4 and would like to upgrade instead of downloading and installing the latest version BackTrack 5 release, you may do so by typing:

# apt-get dist-upgrade


You need not worry about dependencies; all of this is handled automatically by the apt-get dist-upgrade command!

Now that your system has been updated, it is time to start up the graphical user interface (type startx at the prompt again) and have a look around at your new toolkit. We will be making extensive use of these tools throughout the course of this book.


When performing an apt-get dist-upgrade it may be beneficial to follow up with a reboot. This is the case with any kernel upgrade.
