Nmap, a free and open source tool, should be familiar to any security pro that has scanned and mapped a network. Nmap works as a classic command-line tool, and, while very effective, there are times when a visual representation would be more helpful. That's when using Zenmap, an advanced graphical user interface (GUI) included with the Nmap suite, comes into play.
Zenmap allows users to graphically represent a network quickly and easily, document network hosts and identify hosts using unauthorized ports. It also includes Zenmap profiles, a feature that lets users take advantage of predefined profiles (groups of Nmap commands) available via a drop-down menu. Considering the huge number of commands available in Nmap, Zenmap profiles save users significant time and effort by giving them the ability to easily repeat a specific scan.
In this SearchSecurity.com screencast, Keith Barker, CISSP and trainer for CBT Nuggets LLC, walks users through a Zenmap tutorial. He'll provide a brief overview of Zenmap before delving into all that Zenmap's predefined profiles offer. Keith will also divulge one of the features that sold him on Zenmap's uses: its graphical network topology generator. This allows users to graphically represent each device on a network and then color code the devices to display which ones should be analyzed more closely.
In a world where employees bring a multitude of mobile devices onto corporate networks, security pros need to know -- and be able to map -- which devices are connecting to a network at all times. With this tutorial of Zenmap, enterprises learn how to use the tool to achieve greater visibility into the devices that could threaten network security.
