12/16/2023 0 Comments Zenmap scanZenmap scans the network of a particular IP address or domain and displays the domain details. Also, it can be used by beginners to scan the network and discover vulnerabilities. Zenmap makes Nmap easier for beginners and offers advanced features for experienced Nmap users. It supports Windows, Linux, Ubuntu, Fedora, Kali, Mint, MacOS, BSD, CentOS and etc. Zenmap is a free, open-source, and multi-platform application that is the official Nmap Security Scanner GUI and is designed to be used with Nmap. Comparing separate Nmap scan outputs to identify changes on the network.Īlso, through using Nmap in this lab, you know network characteristics, and a better understanding of network and system vulnerabilities, so you can identify and manage network security risks.Recommended Article: Tutorial Configure MongoDB Remote Access on Ubuntu 20.04 What is Zenmap?.Saving and analyzing Nmap scan results.Performing default network scans for devices and services.You have learned, from this lab, how to use Nmap to scan TCP ports using Windows Zenmap, mastering the following: You learn that upon comparing scans, a red highlight or a symbol at the beginning of the line shows that a previous active service is now inactive. After it finishes, you compare the second scan with the one taken in the first exercise. Then you run the second Nmap scan using Zenmap on the Windows machine. First, you log into a Linux host and turn off the secure shell (SSH) service. This lab exercise teaches you how to use the compare results tool. By the end of this section, you know how to navigate the scan’s output and analyze the details shown on Zenmap. Finally, you switch to the services tab and find a HTTP web server on the network. Then you look for the Windows host and its OS. First, you identify your Linux host and its OS. You learn how to read the Nmap scan’s output. Results appear in the Nmap output screen, and you learn how to tell when the scan has finished. The intense Nmap scan takes a couple of minutes to complete as it sends internet protocol (IP) packets, to the most common transmission control protocol (TCP) ports. You can customize Nmap to scan through creating or editing a profile. Instructions relay how to enter a subnet into the target and choose a scan profile. This lab section has you run an “intense” scan, a default Nmap configuration, of a Contoso subnet and save the results, using Nmap through the Zemap graphical user interface (GUI). Finally, you make network service changes, run a second network scan, and compare the two scans to identify the differences. ![]() Next, you save and analyze the scan results. First, you use the free Nmap tool to scan the network. You need to scan the network to identify running hosts and services that might contain vulnerabilities. You are a system administrator for a company that uses servers that run Windows Server and servers that run Linux. At the end of the Nmap scan, a network administrator, system administrator, or security expert knows about network activity, OS updates needed, and where open and closed ports exist. ![]() NMap scans each port identifying hosts and their operating system (OS) and version. The use of the NMap application detects security vulnerabilities and targeted network characteristics. Network Mapper (Nmap) describes a standard, open-source tool that Cyber Defense Infrastructure Support Specialists and Multi-Disciplined Language Analysts use to view what network communications flow to and from computer ports and their open or closed state. Lab set-up consists of two consoles, the virtual Windows server and a Linux virtual machine. Learners will complete the lab within a full forty-five-minute sitting, without pausing and saving work in the middle. This lab will guide beginners who have worked on a Windows operating system and have a rudimentary understanding of how computers use ports to handle network communications. You will redo the Nmap scan on Zenmap and compare the first and second scans, identifying changes. ![]() Then you will switch to a Linux client on the network and turn off a network service on the machine. You will understand how to execute, save, and analyze a Nmap scan using Zenmap in a Microsoft Windows Server 2016 and Active Directory server.
