Nmap (Network Mapper) is a powerful network scanning and security assessment tool widely used by system administrators and security professionals. It is designed to discover hosts, services, and open ports within a network. Nmap works by sending specially crafted packets to target systems and analyzing their responses. Through this method, it can identify running services, operating systems, and network configurations. Nmap is commonly used for network inventory, vulnerability assessment, and security auditing. Its flexibility and accuracy make it one of the most important tools in cybersecurity.
Using Nmap is typically done through the command line interface. Users start by typing the nmap command followed by an IP address, hostname, or network range. Nmap then scans the target and displays information such as open ports and detected services. Advanced options allow users to perform stealth scans, version detection, and operating system fingerprinting. The main function of Nmap is to map networks and identify potential security risks. As a result, Nmap plays a crucial role in network monitoring
