Advanced Infrastructure Penetration Testing

Overview of this book

It has always been difficult to gain hands-on experience and a comprehensive understanding of advanced penetration testing techniques and vulnerability assessment and management. This book will be your one-stop solution to compromising complex network devices and modern operating systems. This book provides you with advanced penetration testing techniques that will help you exploit databases, web and application servers, switches or routers, Docker, VLAN, VoIP, and VPN. With this book, you will explore exploitation abilities such as offensive PowerShell tools and techniques, CI servers, database exploitation, Active Directory delegation, kernel exploits, cron jobs, VLAN hopping, and Docker breakouts. Moving on, this book will not only walk you through managing vulnerabilities, but will also teach you how to ensure endpoint protection. Toward the end of this book, you will also discover post-exploitation tips, tools, and methodologies to help your organization build an intelligent security system. By the end of this book, you will have mastered the skills and methodologies needed to breach infrastructures and provide complete endpoint protection for your system.

Buffer overflow prevention techniques

There are many techniques implemented to avoid buffer overflow attacks. In the upcoming sections, we will cover some of the well-known mechanisms.

Address space layout randomization

Address space layout randomization (ASLR) is a defense mechanism developed by the Pax Project against buffer overflow attacks. This memory-protection process randomizes the executable location when loaded in memory. Because, as we learned in the previous sections, if locations are predictable, then system exploitation will be easy. It started as a Linux patch in 2001, but later was integrated in many other operating systems. ASLR can be defeated using the following techniques:

  • Bruteforcing all the possible...
