Why networking basics still matter

Security feels much clearer when I understand packets, ports, DNS, routes and Linux tools.

Sometimes I want to jump directly to advanced security topics. But networking basics keep coming back.

When I use tools like ping, dig, ss, or tcpdump, I see that many security problems are also network problems.

The important thing is not memorizing everything. The important thing is building a mental model: client, server, port, protocol, route, response.

I want to keep learning this slowly, because strong basics make the advanced tools less mysterious.
