Nessus is used to perform a vulnerability scan during a hacking attack. Zenmap GUI is used to do fingerprinting and port scanning.
It is for the Nmap Security Scanner.
In linux, issue the following command in the terminal.lsof -i TCP | fgrep LISTENOrdo a port scan using a port scanner like nmapex: nmap In Windows, you can do a port scan to get the list of open ports in your computer. For this use, nmap or zenmap (gui of nmap). There could be other ways but this is the one I have experience on.
For mapping a target network in Army cyber security, tools like Nmap (Network Mapper) are highly effective. Nmap can discover hosts and services on a network by sending packets and analyzing the responses, allowing for detailed mapping of the network topology. Additionally, tools like Zenmap, the graphical interface for Nmap, can enhance usability and visualization of the network structure. Together, these tools provide critical insights into network configurations and potential vulnerabilities.
