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.

Using Greenbone Vulnerability Manager

Greenbone Vulnerability Manager (GVM) is an open source vulnerability management tool that enables ethical hackers to leverage Cyber Threat Intelligence (CTI) to efficiently discover security weaknesses in targeted systems.

To get started with setting up GVM, please use the following instructions.

Part 1 – setting up GVM

  1. Firstly, power on the Kali Linux and Metasploitable 3 virtual machines.
  2. Next, open Terminal on Kali Linux and use the following commands to update the software packages repository list and install GVM:
    kali@kali:~$ sudo apt update
    kali@kali:~$ sudo apt install gvm
  3. After the installation is completed, use the following commands to initiate the GVM setup process:
    kali@kali:~$ sudo gvm-setup

This setup process usually takes a few minutes to complete as it downloads additional plugins and updates. Once the setup process is completed, the admin account will be created with a random password, as shown...
