Overview of this book

The current rise in hacking and security breaches makes it more important than ever to effectively pentest your environment, ensuring endpoint protection. This book will take you through the latest version of Kali Linux and help you use various tools and techniques to efficiently deal with crucial security aspects. Through real-world examples, you’ll understand how to set up a lab and later explore core penetration testing concepts. Throughout the course of this book, you’ll get up to speed with gathering sensitive information and even discover different vulnerability assessment tools bundled in Kali Linux 2019. In later chapters, you’ll gain insights into concepts such as social engineering, attacking wireless networks, exploitation of web applications and remote access connections to further build on your pentesting skills. You’ll also focus on techniques such as bypassing controls, attacking the end user and maintaining persistence access through social media. Finally, this pentesting book covers best practices for performing complex penetration testing techniques in a highly secured environment. By the end of this book, you’ll be able to use Kali Linux to detect vulnerabilities and secure your system by applying penetration testing techniques of varying complexity.

Launching a VLAN hopping attack

Organizations usually implement virtual local area networks (VLANs) to segment and improve the performance of their network infrastructure while improving security. When configuring VLANs, there are two main ports that we are concerned with: the access port and the trunk port.

Access ports are those that are configured to connect the end device to the switch. These ports only allow one data VLAN and an additional voice VLAN. When configuring an access port, the VLAN ID is usually statically configured as an access port on a switch.

For multiple VLANs to communicate over a network, trunk ports need to be configured between switches. Trunk ports allow multiple VLANs to pass traffic simultaneously. Trunk ports are configured between switches and are configured between a switch and a router to implement inter-VLAN routing, which allows one VLAN to communicate...
