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.

SNMP: A goldmine of information just waiting to be discovered

Simple Network Management Protocol (SNMP) is commonly mismanaged by busy administrators and developers. Frequently, you will see default community strings, or community strings that are reused throughout the entire organization you are testing. You will want to ensure that your clients are using the most secure version of SNMP and that you cannot simply walk in to a building, unplug a phone, and sniff the community string. Newer versions of SNMP include strong encryption to avoid such flaws.


Luckily for us there are many tools available that make testing for SNMP simple. We will start off by using SNMPEnum which is a Perl script that can be found in BackTrack 5 R1 in the /pentest/enumeration/snmp/snmpenum directory.

If you would like to follow along with these examples you can either skip ahead a few chapters and follow the pfSense installation and configuration walkthroughs or the Ubuntu machine could be set up to use...
