Nmap: Network Discovery and Security Auditing Tool
Open source network discovery and security auditing tool, discovering hosts and services on a network and detecting potential vulnerabilities.
What is Nmap?
Nmap (Network Mapper) is an open source tool for network exploration and security auditing. It allows users to discover hosts and services on a network, port scan them, and detect potential vulnerabilities.
Some key features of Nmap include:
- Host discovery - it can quickly scan large networks and detect which devices are up.
- Port scanning - it can determine which ports are open on hosts, indicating which services/applications are running.
- Version detection - it can determine the application name and version number running on open ports.
- OS detection - it can guess the operating system running on remote devices.
- Scriptable interaction - its NSE scripting engine can run customized scripts to detect vulnerabilities or gather further information on target hosts.
Nmap is highly flexible with numerous scanning options. It allows for basic ping scans up to more advanced TCP scans to detect open ports and applications. The data it collects during scans can be used to improve security auditing and avoid potential weaknesses. It's an essential tool for network administrators, security analysts, and ethical hackers.
