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.

Looking at traffic patterns

Network sniffing can be a huge time saver. It is more difficult to use remote Windows machines to perform this task for you as the network card needs to be in promiscuous mode, but it can be done. Ideally, you will find a Unix or Linux host that can be turned into a listening station with little to no effort.

Here we look at a compromised Linux host on the subnet. Our attacking machine resides on and cannot see the same traffic that the Linux machine does. We will use tcpdump which is readily available to many Linux distributions:

tcpdump -i eth0 -c 100 -n

Here we invoke tcpdump on the remote Kioptrix machine we have SSH'd into using the games account we set up during the post exploitation chapter. We use the -i option to specify that we would like to use eth0 as our listening adapter. We then tell the adapter to only capture the next 100 packets. The -n switch is used to avoid DNS lookups and will display IP numbers rather than...
