Applications:Nmap

By PJan

a. Nmap is an open source tool used for network discovery and security auditing. Zenmap is different than Nmap in terms of Zenmap making it easier for beginners to use Nmap's powerful features without needing to memorize command-line options, allowing users to scan save profiles, view visual representations of network topology, and is typically more accessible for users who prefer a point-and-click interface.

b. I installed Nmap on my personal computer running Windows 11.

c. The problems I ran into are permission issues when running scans, incomplete or incorrect scan results and Zenmap not launching on Windows. The solutions that I came up with are to run Nmap with root privileges using sudo, as some scanning options require higher privileges (e.g., sudo nmap <target>), ensure the firewall settings on the target machine allow the required types of network traffic. Some scans may require adjusting firewall rules or network settings, and ensure the correct version of Python is installed, or reinstall Zenmap with the required dependencies.

d. From running scans in Zenmap and Nmap the information I learned about based on my network are open ports where it’s easy to identify which ports are open on various devices on my network, services and versions where Nmap can reveal which services are running on those ports and even identify their versions, operating systems in which Nmap's OS detection feature can help identify the operating system running on a device, and vulnerabilities based on the results, you can detect potential security vulnerabilities, such as outdated services or open ports that shouldn’t be accessible.
