Hey This is KingLucifer aka Axeman! Today we will learn about N-Map in KALI Linux.


1.Nmap.

    1.1. N-map is the often refereed to as King of scanners. It is the most advanced tool for performing network scanning. And we will also see about Zenmap, it is the Graphical version of Nmap as it is a command line tool. N-map offers advanced features in network discovery and auditing.

 

    1.2. In Cyber security, we normally use n-map to detect the devices connected on the network, determine services running them, versions of the specified services, and even the operating system running on the target system. It uses raw packets to perform the specified tasks.

 

2. How to use Nmap in Kali Linux.

     2.1. Fire up your Kali Linux and go to

Applications ----> Information gathering ----> Zenmap.

     2.2. We are going to use  the GUI Version of Nmap as it is easy to use and comfortable for people with not much command line experience.

 

3. Discovering Hosts.

      3.1. The first step in information gathering phase is to determine the connected clients. A network can support over more than 200 clients. Scanning the information on all of these devices can take a while. Nmap offers a very efficient way to perform host discovery in order to find your target device on the target network.

 

      3.2. Let us start up Kali Linux and Metasploitable to perform host discovery.

 


        3.3. Once you launched ZenMap (refer above image), Enter your network gateway/24, which scans the entire network subnet. The illustration below show nmap intense scan of the entire network (image for illustration purpose only)
