What is Nmap?
Nmap is a free and open-source network scanner used for security auditing and network exploration. It helps professionals understand the structure and vulnerabilities of computer networks. This tool is widely adopted by network administrators, security experts, and ethical hackers to maintain secure and efficient network environments. People use Nmap to discover active hosts on a network, identify open ports, and determine what services are running on those ports. It can also detect operating systems and device types, providing a detailed map of the network's infrastructure. This information is crucial for assessing security postures and identifying potential weaknesses.
