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.

Switching in networking

Switches are data link layer (layer 2 in the OSI model) devices. Their main goal is connecting networking devices by receiving switching packets and forwarding them to the destination devices. Switching is an efficient solution for connecting devices, though it is not practical if we want to connect a large number of end-system devices (computers, phones, and so on) and nodes. A node is an entity that carries information from a source to a destination without modifying information or data; a set of nodes is called a communication network, as shown here:

In switching, there are three different techniques:

  • Circuit switching: This is a fixed channel between the sender and the receiver, and the dedicated channel is called a circuit. Once a connection is established, no other devices can use the channel, even if the circuit is not fully used until the connection...
