This book is an excellent guide for you on how to use Nmap 7. The first part of the book guides you on how to get started with Nmap by installing it on the various types of operating systems. You are then guided on how to scan a network for SMB (Server Message Vulnerabilities). This will help you learn how to gather information from a target host. You are also guided on how to scan a network for the open ports. Such ports are an advantage to hackers, as they can allow them to gain unauthorized access into your network. Information encrypted with SSL/TLS encryption is prone to the heartbleed bug. You are guided to test whether your information is vulnerable to this bug. The process of determining the live hosts on a network is also explored in detail. Live hosts can be compromised for an attacker to gain valuable information from such hosts. The process of scanning a network firewall is also examined in detail. This will help you determine the ports which are open. You will also learn the services which have been assigned to the various ports on the firewall. The process of performing layer 2 discoveries with Nmap is explored in detail, thus, you will know how to do it. You are also guided on how to grab banners using Nmap. The process of gathering network information with Nmap as well as penetrating into servers is then discussed.
