It also identifies the service and role of a device. It can identify all kinds of devices such as servers, routers, and switches, and this makes it particularly helpful for capacity planning and inventory management. Nmap can easily discover devices on a network and their physical connections. Also, you can use it on many ports and for many purposes, and this flexibility is what makes Nmap so popular, even 23 years after it was first released. Nmap supports different protocols such as Transmission Control Protocol (TCP), User Datagram Protocol (UDP), Stream Control Transmission Protocol (SCTP), and Internet Control Message Protocol (ICMP), so you can use it to send messages to a wide range of devices. Supports different protocols and operating systems This is particularly useful for identifying vulnerabilities quickly. You can easily create a hardware and software inventory of your network. Nmap sends out packets to other devices, and it comes back with a wealth of information such as IP addresses, network attributes, and more to give you a precise idea of the devices and your network. Here are some things you can do with this tool. Its true power lies in its flexibility and versatility. Port scanning is the core functionality of Nmap, but over the years, it has evolved to perform wide-ranging activities for its users. Provides network information such as DNS names and device types.Īs you can see, these features are comprehensive and cover almost every aspect of network monitoring, and it justifies the de facto standard position that it enjoys today.Monitors hosts to detect and identify a new device or access.Gets the accurate path by routing packages to the target machine.Detects the underlying operating system and hardware characteristics of devices.Checks remote devices to identify the applications and their versions.Lists the number of open ports in a network, as this is a major vulnerability point.For example, you can list devices that respond to ICMP requests or those that access a particular open port, and so on. Identifies hosts on a network based on different criteria.Nmap is popular because it can do a ton of things for IT security professionals. Even today, it continues to be one of the most useful utilities on Linux and Windows. It started as a utility for Linux and was ported to Windows, macOS, and other operating systems because of its usefulness. Network Mapper, or Nmap for short, is a free open-source tool used to scan networks, identify vulnerabilities, find open ports, discover hosts automatically, and more. In this article, we’ll take a deeper look into this powerful network monitoring tool is and why it is so important for network administrators. Out of these many network monitoring tools, Nmap stands out and is even considered as the de facto standard due to its versatility and utility. The good news is many monitoring tools and utilities are available today to ease this workload of network administrators and to enhance their productivity. In fact, a report by Cisco shows that 35 percent of network strategists believe network troubleshooting is the most time-consuming and resource-intensive activity for network administrators. Unfortunately, identifying and fixing vulnerabilities continues to be a highly manual task. This is a race against time to identify and fix bugs before cyber attackers get to it. Network administrators and IT security personnel are always on their toes to have complete control over what’s going on in their organization’s network and to identify vulnerabilities at the earliest. Monitoring is an important aspect of all networks as it prevents attacks and identifies vulnerabilities at the earliest.
