I'm middle-aged and deeply interested in technology and cybersecurity. I've spent time working with operating systems, including taking them apart and experimenting with them, and I currently use Arch Linux. I'd like to learn ethical hacking in a structured way, but I'm unsure how to begin with networking or what to study afterward. What networking concepts should I learn, how far should I take them, and which books, courses, or hands-on resources would you recommend? I'm learning out of personal interest rather than for a job, and I want to practice only in systems and labs where I have permission.

Choose a direction after learning the basics. Web security, internal network testing, malware analysis, cloud security, and defensive monitoring all require different knowledge. For networking, focus on how devices communicate and how to troubleshoot them rather than memorizing every command. Build small projects, take notes, read documentation, and regularly explain what you learned in your own words. There’s no shortcut resource that replaces consistent practice.
Set up a legal practice environment on your own computer using virtual machines or intentionally vulnerable targets. Guided platforms such as TryHackMe and Hack The Box can provide structured exercises, and many beginner material is available at no cost or with limited free content. A practical sequence would be networking fundamentals, Linux and Windows administration, Python or shell scripting, web basics, then defensive and offensive exercises in isolated labs. Keep everything authorized and never test public systems without explicit permission.
There isn’t really one skill called “hacking.” You need to understand the systems you’re testing first: networking, operating systems, web applications, authentication, and basic programming. Think of it like studying a building’s locks, cameras, alarms, and layout before figuring out how each part could fail. Start with TCP/IP, DNS, HTTP, routing, subnets, ports, and common protocols, then reinforce each topic with a small lab instead of spending months on theory alone.
That makes sense. I’m mainly looking for a good path through networking and recommendations for resources, rather than trying random topics.
Hands-on practice helped me understand networking much faster than reading alone. Even a couple of virtual machines and a packet analyzer can teach a lot when you deliberately inspect the traffic.
