NMAP, known as Network Mapper, is a free and open-source utility often used for network discovery and security auditing. It can identify what devices are running on your network, discover open ports and services, and detect vulnerabilities.
To install NMAP on Windows, follow the steps below:
1. Downloading NMAP:
Go to the official NMAP download page at `https://nmap.org/download.html`. Under the stable release section, click on the link for the latest Windows installer.
1. Installation:
Once the file is downloaded, double-click on it to launch the installer. A setup guide will pop-up. Click ‘Next’ to start the installation process. Follow the on-screen instructions available in the installation wizard. You’ll need to agree with the terms of the license, and you may choose whether you want to install an additional GUI for NMAP, called Zenmap. After that, click on the ‘Install’ button and wait until the process finishes.
1. Confirmation:
After the installation is complete, there are two ways to verify the installation:
a. Command Line:
Open the Command Prompt by searching ‘cmd’ in the Windows search bar. You can then check if NMAP is installed correctly by typing `nmap` in the command line. If it’s installed correctly, it will list out the NMAP commands.
b. GUI with Zenmap:
If you installed Zenmap (Nmap’s official GUI), you can open Zenmap from the Windoews start menu. Once Zenmap opens, you can test it by typing `nmap` in the command area, and then clicking on the ‘Scan’ button. If it’s working properly, you’ll see the same commands output like the one in the command line.
This installation process is derived from the official NMAP documentation: `https://nmap.org/book/inst-windows.html`
Take note that using NMAP requires some technical knowledge of networking and related concepts. If you are unfamiliar with these topics, Nmap provides an official guide (`https://nmap.org/book/man.html`) which outlines the many commands and options Nmap offers to users. Moreover, while using NMAP, bear in mind that any kind of unauthorized scanning can be perceived as a network attack and could lead to legal repercussions.
