Running head: QUANTIFYING A NETWORK USING NMAP 2

NMAP is a network mapper that makes it easy to detect changes and new systems on the network. Typically, it is used in host delivery, port scanning, version detection, and OS detection. In this case, I am using the Nmap software to quantify my home network on my pc. I am using the Windows operating system; therefore, below are the steps on installing and configuring Nmap GUI software on the Windows operating system.

First of all, I will start with the steps taken by the Hacker to access this home network on my pc;

The Hacker will identify the system network IP address. If the IP address of the network is found, the Hacker will use the address to scan the ports on my home network. The Hacker will get the information of the system by conducting passive footprinting.

Installation and configuration of NMAP software in windows operating system;

Step 1 – Browse to https://nmap.org/download.html and download the latest self-installer

Step 2 – Run the downloaded .exe file. In the window that opens, accepts the license terms;

Step 3 – Choose the components to install. By default, the Zenmap GUI will be installed;

Step 4 – Select the install location and click install

Step 5 – The installation should be completed in a couple of minutes

Below are some of the screenshots that show how Nmap software detects my home network on my computer system.

In the first screenshot, the ports are being scanned to find the information about them. This shows who is on the network

The second screenshot shows the active ports found after the scanning has been performed by the nmap toolkit software. This shows what is in the network.

The screenshot below finds the Ports/Hosts tab for a detailed list of all the open ports found on the target host.

The Policies implemented – the network policy describes an organization's security control. This aims to keep malicious users out while mitigating risky users within the home network organization. The security policy defines the policies that will be enforced. For example, Nmap helps secure the network from hackers, as it makes it easy to find any security flaws in systems easily. Whether port scanning is legal on external servers is another concern. In this region, the legislation is complex and varies by territory. Using Nmap to scan external ports can lead to a ban by ISP; that is why we have to make sure we study the legal consequences of using the program before using it more widely.
