Nmap (Network Mapper) —-— is a powerful network scanning and analysis tool used to identify active devices, determine open ports, and get information about services running on those ports. Nmap is widely used by system administrators, security professionals and network engineers to secure network infrastructure.
How does Nmap work?
- Host scanning: Nmap sends packets to target IP addresses and analyzes the responses to determine which devices are active on the network.
- Defining open ports: Nmap can scan port ranges to determine which ports are open and available for connection.
- Defining services and versions: Nmap can identify services running on open ports and determine their versions, which is useful for vulnerability assessment.
Nmap — is an indispensable tool for network administrators and security professionals to help secure networks and identify vulnerabilities. Its powerful features and flexibility make it a popular choice for analyzing network infrastructure.
