What Is Nmap In Cyber Security and what Are The Uses Of Nmap

Hi dear, Welcome to the Nmap tutorial. In this post, you will learn everything about Nmap. 

So, let's get started with what an Nmap is.

what is nmap

Nmap is a networking mapping tool widely used for pen-testing and has a main role in scanning. There are a large number of networks for the port scan and this service scan. 

If you go to the official website of Nmap, you can see it is the official website of Nmap. The website is namp.org. So, it has a lot of options, and you can go for the list of IP ranges as well. You can go for the list of port ranges, so if you want to scan one to one hundred ports, you can go for that; you can go for all the options and introductions. You know the installation guide and everything, so you can even go for the download process for Windows; if you're using a Windows machine, you can see the latest version, and this is for Windows installation. I will show you how to install it on Linux and your mobile OS.

You can see that the Nmap setup.exe file is for Windows, so if you click on that setup.exe, then if you are using Windows, it will automatically download the file to your system.

So, let's jump into the Kali machine directly and see how Nmap works. We can use a fuzzy-scan Nmap, and first, you have to work out the tool name and the space of your target IP address. So, in this case, the tool name is Nmap and space your target IP. Right now, I will target the Metasploit machine because it is a server running on my local host. So, as you can see, this is the Metasploit machine, and it has an IP of It is on my land, so I can attack and play with everything.

So, you can see my Kali Linux is running far away.

So, you can see the terminal here and open up your terminal by typing here. You can tap on this icon to open up the terminal. So, Kali and the Metasploit framework are in the same environment. I can attack this Metasploit framework machine.

For example, if I know this IP, it is I will scan for the first scan with the Nmap, and if I write Nmap space target IP, this gives metasploitable IP 2 3 4 5 6 -------. 

By pressing enter, you can see all the results with the Nmap, and I can center the report for the IP address.

The host is up, and you know this IP address is alive in the network. There is a port for the local IP, but if you are going to scan for other domains like Facebook, Google, and others. So, it will take longer, like one to two minutes, now this going 977 closed ports.

Nmap (short for Network Mapper) is a free and open-source security tool that network administrators and cybersecurity professionals widely use to discover and analyze networks and their devices. Developed by Gordon Lyon (also known as Fyodor Vaskovich), Nmap was first released in 1997 and has since become one of the most popular and powerful network scanning and security tools available.

Nmap is available for all major operating systems, including Linux, Windows, and macOS, and can be run from the command line or with a graphical user interface. It is highly configurable, with a wide range of options and features that allow users to customize the behavior and output of their scans. Nmap supports a variety of scanning techniques, including port scanning, OS and service detection, ping sweeping, and vulnerability detection, making it a versatile and valuable tool for network administrators and security professionals.

One of the key features of Nmap is its ability to detect the operating systems and services running on the devices on a network. This is accomplished by sending specially crafted packets to the target devices and analyzing the responses to determine the operating system and services running on each device. Nmap can identify a wide range of operating systems and services, including popular platforms like Windows, Linux, and macOS, as well as many less common or obsolete systems.

In addition to OS and service detection, Nmap can also be used for port scanning, which involves systematically scanning a range of IP addresses and ports to determine which ports are open and listening on each device. This can be useful for identifying services and applications running on a network and potential vulnerabilities and security risks. Nmap includes several different port scanning techniques, such as SYN, ACK, and FIN, each with advantages and disadvantages.

Another useful feature of Nmap is its ability to perform ping sweeps, which involve sending ICMP echo request (ping) packets to a range of IP addresses to determine which hosts are active and responding. This can be useful for quickly identifying the devices on a network and deciding which ones are online and accessible. Nmap can also perform advanced network discovery techniques, such as ARP scanning and DNS resolution, to provide a more detailed view of the network and its devices.

In addition to its core scanning and discovery capabilities, Nmap includes a range of vulnerability detection and exploitation features. Nmap can be configured to run various NSE (Nmap Scripting Engine) scripts, which are small programs that can automate common tasks, such as scanning for vulnerabilities or extracting sensitive information from the target devices. Nmap also includes built-in scripts that detect common vulnerabilities, such as weak SSH credentials, unpatched software, or insecure protocols.

In conclusion, Nmap is a powerful and versatile security tool that network administrators and cybersecurity professionals widely use to discover and analyze networks and their devices. With its ability to detect operating systems and services, perform port scanning, and run vulnerability detection scripts, Nmap is an essential tool for anyone looking to improve the security of their networks and systems.
