How to Find the Best Nmap Scan for Penetration Testing Initiatives – EC-Council

Setting up a pentesting Nmap is easy since this tool works on a wide range of operating systems and is easily customized to meet the specific needs of any environment. Still, if you have never used such a tool before, exploring its functionality is important to get the most out of it.

In older versions of the tool, you would need to be comfortable using the command line interface (CLI) to control scans and other functions. However, you can now use Zenmap, an add-on that offers a graphical user interface (GUI) so anyone can use it easily.

However, you decide to interact with the tool, you first need to define the ports you would like it to scan. This does not require a specific list but a range of ports youd like to check. You can also scan all ports on your network, which would take far too long in most environments. Instead, most developers divide known ports into ranges and schedule each group for scanning incrementally.

Aside from defining a range of ports to scan, you should also tell it what information you want it to collect from each port. The depth of a scan can range from limited to deep, collecting basic information like whether or not a port is open or more detailed information, such as what devices, operating systems, and services are interacting with those ports.

Because this tool allows you to discover very in-depth information about ports, including the version of services active on a given port, its a powerful tool for revealing vulnerabilities in your network. Whats important is that you know what youre scanning for to make sure you manage resources wisely and garner valuable information in the process.
