- It helps you identify unusual network activity, like malicious traffic or unauthorized data transfers.
- You can use it to troubleshoot network issues by examining packet-level details.
Beginner Tips:
- Start by capturing traffic on your local network and filter packets by protocols like HTTP, TCP, or DNS.
- Use Wireshark’s built-in color-coding to quickly identify different types of traffic.
Cost: Free and open-source.
2. Nmap: Scanning and Mapping Networks
Nmap (Network Mapper) is a practical and versatile security tool for scanning networks to discover devices, open ports, and services running on those ports. It’s used for network discovery and security auditing.
Why Learn Nmap?
- It’s essential for conducting network reconnaissance, a critical first step in penetration testing.
- Nmap helps identify vulnerabilities—potential entry points of attackers—by revealing open ports and services.
Beginner Tips:
- Practice basic commands on your own network. For instance, you can use nmap -sP for a simple ping scan or nmap -sV to detect service or daemon versions.
- Learn to interpret scan results to understand the layout and potential weak points of a network.
