Managing networks and all the processes associated with it can become a complex task due to the number of services, processes and resources that come into play when using any network service. As administrators we must be aware of factors such as:
NMAP factors
- Open and closed ports with their respective service
- Protocols that interact in a network process
- Times for sending and receiving packages
- Percentage of packets sent and received correctly and much more
To help optimize this, it is possible to make use of Nmap which is a well known utility.
Nmap, Network Mapper, has been developed as a tool to detect networks and carry out security audit processes, Nmap makes use of raw IP packets in order to indicate which computers or hosts are available on the network, the services with the name and version of the application active there, the operating system, with its version used, the firewall filters configured and more options that can be configured during the analysis process..
NMAP utilities
Nmap can be used on Linux, Windows and Mac OS operating systems and at the time of its installation it is possible to access utilities such as:
- Zenmap which is an advanced GUI to access the results
- Ncat which is a flexible tool for data transfer, redirection and debugging tasks
- Ndiff with which it is possible to compare scan results
- Nping which, as its name indicates, is a PING packet generation and response analysis tool
NMAP Features
Among its outstanding features we find:
- Available for various modern operating systems
- It supports more advanced utilities and techniques for mapping networks including IP filters, firewalls, routers and more.
- Can scan large numbers of networks
TechnoWikis will explain how to use Nmap in Windows 11 to basically scan the network.
