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.

Domain intelligence

Domain intelligence focuses on collecting and analyzing domain registry details and DNS records of a targeted organization to identify their systems, network infrastructure, and attack surface. As the internet continues to expand, there are more registered domain names on the internet as more organizations create an online presence to extend their market reach to new customers around the world. In addition, it’s quite easy for anyone to register a public domain name on the internet and use the namespace for their personal usage. Domain names have been around for quite some time, and they help us to easily access websites on the internet. For instance, imagine how challenging it would be for each person to know and record the IP addresses of each website they wanted to visit. If the IP address were unknown, then the user would not know how to connect to the destination website. Similarly to a postal service, if the destination mailing address is unknown, then...
