Getting ready

Nmap is available in various versions and formats based on the architecture and operating system supported by the user machine. Nmap also has a GUI version, called Zenmap, which provides better visibility of the options to select the commands to run. It is also available as a default tool as a part of operating systems used for exploitation and hacking techniques, such as Kali Linux. A user can choose the type or the version of Nmap based on their machine's configuration; for example, I am using a Windows 7 64-bit operating system, so I will choose the latest stable version of the executable that supports the 64-bit Windows 7 operating system. If you are using a 64-bit Linux or Unix distribution, there are rpm binary packages available for download at https://Nmap.org/.
