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.

Exploiting routers

Previously, we saw how to exploit routing protocols. Now it is time to learn how to exploit modern routers.

Router components

Like every major networking device, a router is composed of many internal components:

  • CPU: Executes system operations
  • RAM: Used to store instructions
  • ROM: Contains boot instructions
  • Flash: Contains the IOS
  • NVRAM: Contains the startup configuration file:

Router bootup process

To boot up, every major router goes through multiple steps:

  1. First, the router performs a POST.
  2. It loads the bootstrap.
  3. It locates and loads the operating...
