Nmap : Network Mapper (Best and Free) tool for Information Gathering and Scanning.

What Is Nmap?

Nmap is the best and free network scanner tool available in the market. It can be used to determine what hosts are available on the network, what services (application name and version) those hosts are offering, what operating systems (and OS versions) they are running, what type of packet filters/firewalls are in use, and dozens of other characteristics.

Why Nmap?

Nmap not only scans and tell all the hosts and ports in the network, It also does a lot more like OS identification, If firewall active then try to evade firewall, Can fragment packets too and many more…

But the reason I prefer Nmap is its Nmap Scripting Engine(NSE). It is the heart and soul for every penetration tester. NSE provide hundreds of scripts to Check diffrent service and vulnerabilities in the target server

For example: It can determine http methods used, SSl certificates use, Heartbleed vulnerability available or not and millions more.

It also gives developers an easy to use an include platform for creating their own scripts and run through Nmap.

Nmap Availability?

Nmap is available for all the OS in the market. It can be downloaded here.

How to use Nmap?

As mentioned earlier, It might be the easiest tool to use. I have created a video describing its use, can see here.

It can be basically used by just writing the following command

nmap <Target url/IP>
