Network Mapping
Network mapping is the process of discovering and visualizing the devices, connections, and topology of a computer network. It involves using specialized software or tools to scan and identify active hosts, services, and their interrelationships, often creating graphical representations like maps or diagrams. This helps administrators and security professionals understand network structure, monitor performance, and identify vulnerabilities.
Developers and IT professionals should learn network mapping for tasks such as network troubleshooting, security auditing, and infrastructure planning. It is essential in cybersecurity for penetration testing to identify attack surfaces, in system administration for maintaining network health, and in DevOps for managing cloud or hybrid environments. Tools like Nmap or Wireshark are commonly used for this purpose.
