Shadow IT is often hidden and even if these machines are not necessarily malicious, they can be a risk factor for the system. This helps admins discover any officially unauthorized device – shadow IT – connected to their network. Nmap shows both the type and the location of machines connected to the network. But more interestingly, they can also determine the patch level of the OS and the estimated uptime of the endpoint. By this process, they find also find out what brand (Dell, Acer, Lenovo, etc.) the machine is. Helps the IT team discover all the types of OS-s that run on a device. The IT team then has a heads-up and can avoid the cyberattack by patching the system in a timely manner. When a new vulnerability is discovered to affect a specific software or version of the software, Nmap can show if any of the connected machines use that app. Nmap also helps discover how vulnerable the network is to a specific threat. It also comes in handy for those who want to prepare against a port scan attack. This feature comes in handy to IT teams who use it to see if the firewalls work properly. You can use Nmap to check which ports are open and which are closed. They also learn how they work together and can further imagine a network map. With this command, they see how servers, routers, switches, and other devices are connected. Nmap shows the user what types of devices are connected to the network and use the scanned ports. Here below is a list of the most important Nmap tool functionalities: Network Mapping Nmap was created by the American network security expert Gordon Lyon. One of its most recent employs is to analyze the traffic between web servers and IoT devices. It is used for penetration testing, ethical hacking, and, of course, more ignoble purposes. What Is Nmap Used For?īasically, Nmap enables the user to do fast network mapping and can help a team optimize and protect networks and data. Nmap also enables them to see what ports are open and discover potential vulnerabilities. The source code is available in C, C++, Perl, and Python and the tool can be customized to work in different environments.Īdmins use it for penetration testing, to check what devices are running on their network. Users can also employ Nmap on less common systems: Solaris, AIX, or Amiga OS. At first, it was developed as a Linux tool but is now available also for Windows and MacOS. System and network admins use it for network inventory, managing service upgrade schedules, and monitoring service uptime. Nmap is short for Network Mapper, an open-source tool used for IP and port scanning and app detection.
