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.

Buffer overflows—A refresher


Buffer overflows are the bread and butter of attackers in the wild. When this type of vulnerability is properly exploited, an attack may lead to complete system compromise in mere seconds. Ideally, many of these vulnerabilities may be prevented by the proper implementation of a security development lifecycle. If your client does not have such practices, you may be required to perform steps above and beyond standard penetration testing and prove that there are flaws in the (often internally developed) applications being deployed across the enterprise.

Note

Not all buffer overflow vulnerabilities can be used to create remote exploits. Also of note is that not all buffer overflows are exploitable.

More often than not, programming errors that allow for buffer overflows are not intentional, or due to lazy developers. Frequently, buffer overflow vulnerabilities are missed during the application development stages because of either the complexity of the application, or...
