Zenmap is the graphical user interface (GUI) version of Nmap and is supported on multiple platforms, such as Windows, Linux, and macOS. The creation of Zenmap was geared toward beginners as it's easier to use than the traditional command-line interface of Nmap. To download Zenmap on your system, please visit https://nmap.org/zenmap/.

The following shows the Zenmap interface. It's quite simple to use: simply enter the target and select the type of scan you would like to perform. Depending on the type of scan you select, the necessary Nmap operators will be set in the command field.

To demonstrate, let's perform a quick scan on our Metasploitable VM by observing the following steps:

1. Enter the IP address of our target.
2. Select the Quick scan option from the Profile menu.
3. Click on Scan to begin, as shown in the following screenshot:

Once the scan has completed, click on each tab to get further details about the target. If you're performing a scan on an entire network, the Topology tab will help you create a network diagram of the target network.

Customized scanning profiles can be created on Zenmap by performing the following steps:

1. To create a new scanning profile, click on Profile | New Profile or Command.
2. The Profile Editor will open, providing you with all of the options available for scanning in Nmap, as shown in the following screenshot:

Be sure to visit each tab and familiarize yourself with the various options available, since they will be useful in the future.

As you saw, Zenmap is very easy to use and user-friendly. In the next section, we will learn about Hping3, another tool with which to perform scanning.
