I'm currently taking a deep dive into Nmap, the powerful network scanning tool that so many security pros rely on. But instead of just reading results in the terminal, I wanted to go a step further…</p> <p>💡 I'm pairing Nmap with Wireshark to observe the actual packets being sent and received during different types of scans.</p> <p>So far, I've been experimenting with:</p> <ul> <li>SYN scans (-sS)</li> <li>Connect scans (-sT)</li> <li>OS detection (-O)</li> <li>Ping sweeps (-sn)</li> </ul> <p>By watching the network traffic in Wireshark while I run these commands, I’m learning a ton about how each scan behaves under the hood — what packets are sent, what responses come back, and how Nmap builds its results.</p> <p>This hands-on combo has been super insightful for understanding how tools like Nmap interact with networks at a packet level.</p> <p>I'll be sharing more stuff soon.</p> <p>Cheers to learning by doing 🛠️<br> -Matt</p> cybersecurity nmap wireshark learning
