Overview of this book

This book explores reconnaissance techniques – the first step in discovering security vulnerabilities and exposed network infrastructure. It aids ethical hackers in understanding adversaries’ methods of identifying and mapping attack surfaces, such as network entry points, which enables them to exploit the target and steal confidential information. Reconnaissance for Ethical Hackers helps you get a comprehensive understanding of how threat actors are able to successfully leverage the information collected during the reconnaissance phase to scan and enumerate the network, collect information, and pose various security threats. This book helps you stay one step ahead in knowing how adversaries use tactics, techniques, and procedures (TTPs) to successfully gain information about their targets, while you develop a solid foundation on information gathering strategies as a cybersecurity professional. The concluding chapters will assist you in developing the skills and techniques used by real adversaries to identify vulnerable points of entry into an organization and mitigate reconnaissance-based attacks. By the end of this book, you’ll have gained a solid understanding of reconnaissance, as well as learned how to secure yourself and your organization without causing significant disruption.

Setting up a hypervisor and virtual networking

There are many hypervisors that are available in the industry; however, we’ll be using Oracle VM VirtualBox as it’s free and simple to use while containing all the important features and components needed for our lab environment. In this section, you will learn how to set up a hypervisor and virtual networking.

Before getting started, please ensure your system meets the following requirements:

  • Ensure the VT-x/AMD-V feature is supported on your processor
  • Ensure the virtualization feature is enabled on the processor via the BIOS/UEFI

Most modern processors support VT-x (Intel) or AMD-V (AMD), a technology that enables the host operating system and applications to leverage the virtualization features of the Central Processing Unit (CPU). However, some computer vendors do not enable the operating system to leverage the virtualization feature of the processor. Hence, it’s important to manually access...
