    Network Analysis and Packet Sniffing with Nmap

    Network security scanning is an important part of safeguarding your network and its data. Nmap is a powerful network scanning tool that can help you identify the vulnerabilities and security issues in your network.

    Here are some tips on how to use Nmap for network security scanning:

    1. Start by scanning your network for open ports. Nmap has a variety of scanning options that can help you scan your network for vulnerable open ports.

    2. Use the nmap port scan command to scan specific hostnames or IP addresses. This will help you identify the vulnerabilities and security issues on the target system.
