#INET NETWORK SCANNER 1.3.9 HOW TO#

In this tutorial, we’ll cover how to install it on Linux operating system, however the Nmap commands are similar on all platforms once you install Nmap on your OS, so you should be able to go through this tutorial no matter what OS you are using. Installing Nmap is pretty straightforward. However, if you are running any other operating systems, you have to install Nmap first. If you are running one of the operating systems that are designed for penetration testers such as Kali Linux, Nmap should come with the OS as a pre-installed package.

It is available for Linux, Windows, and MAC operating systems. Nmap is one of the most used network mappers out there. With all that basics out of the way, let’s get into some details of the Nmap package. That’s why Network Discovery plays a paramount role in securing a network system and performing security audits.Įthical hackers and penetration testers will use this technique often to find out weaknesses in the network and secure it before the hackers can take advantage of the flaw. You will also have to know your systems in and out, actively searching for potential weaknesses and removing them as soon as possible. How will you defend your system against such parties? By playing their game against them. These are some of the things that can be done through network discovery with ill intent.įurthermore, if there is one single device on your network with security flaws, the whole network could become compromised! Which program has a vulnerability that the hacker can exploit ( open doors with weak security).The program/service running on the open port ( what’s behind the door).What ports are open to the internet ( open doors in the bank).What devices ( banks) there are in your network.Just as you might have imagined the group of robbers will be gathering information about the bank first, a malicious hacker will do the same to your network or system. Getting back to our point, we’ll see why this network discovery is so important to keep our system secure. They will rob the bank exploiting the bank’s weakness.ĭon’t get the wrong idea – the aim of this tutorial isn’t the malicious use of information gathering.

If found, this weakness will play a crucial role in their success and the plan will form around this weakness.

They will try to find a weak spot in the system.

How many gates are there, how many are open, what’s behind the door, how secure the doors are, etc.

How the bank operates, the building structure.

They will try to gather information about the bank as much as they can through active or passive reconnaissance. The first step most likely is information gathering. What is the first step those robbers are going to perform? Let’s imagine a group of robbers that’s planning a bank heist, like in the movies. We’ll use an analogy to describe how important network discovery really is. So, what is network discovery? In simple terms, network discovery is the process of finding out the devices that are on the network. If you think you’re knowledgeable enough about network discovery, you could skip this section. In this section, we’ll be talking about what network discovery is and why is it important.

We already said Nmap is a network discovery tool. Scanning specific ports or a range of portsīefore we take a deep dive into Nmap commands, we need to learn more about what it does.

Finding out active hosts within a range of IP addresses.

A brief word of caution before we get started.

Nmap Scan Types – Host Discovery, Port Scan, OS detections, and Service detections.

Install Nmap on CentOS and other RPM Based Distros.

Install Nmap on Ubuntu and other Debian Based Distros.
