What Can NMAP Do for You?

Network Mapper, or "NMAP" for short, is a powerful open-source tool that will allow you to scan local or remote networks to develop a deep understanding of what's actually happening. Some of the most critical features include:

  • Nping: A tool to generate packets and analyze responses.

  • Zenmap: An advanced graphical user interface (GUI) to review and explore results.

  • Ndiff: A utility that allows you to compare different scan results.

  • Ncat: A tool that facilitates flexible data transfer, redirection, and has debugging features.

Although you can get nearly as advanced with NMAP as you can imagine, there are a few dozen basic commands that form the foundation of network mapping. These fall into several major categories, such as:

  • Target selection: Scanning single IPs, a range of IPs, or a host.

  • Port selection: Scanning single ports, a defined range, or all ports on the network.

  • Using scans with various tools: These include TCP connect and TCP SYN scan.

  • Viewing and interpreting results: You can easily export results in various file formats and save the data for other uses.

  • Leveraging scripts: NMAP will allow you to scan using specific unique scripts, default scripts, and update the script database with your preferences as needed.
