Before getting started

First, you need to understand what cybersecurity is.
It is the act of securing the digital world: systems, networks, applications, and data.

Once you understand that, you’ll realize it relates to almost every field in IT, and sometimes even non-IT areas like law, compliance, and policy.

To begin, there are two paths you can take to become successful in cybersecurity. As mentioned earlier, every field eventually needs security.

The First Path: Master the Thing Itself

For example, master networking, operating systems, or web development.
When you deeply understand how something works, you naturally become confident in securing it.

This is the long path:
become the chef before you protect the kitchen.

The Second Path: Master the Mistakes

Instead of becoming a master chef, you study what is necessary to inspect the kitchen; hygiene rules, safety standards, common mistakes, and weak points.

You may not cook every dish, but you know exactly where problems hide.

And here’s the interesting part:
Even great chefs can fail to recognize their own blind spots.

That’s where a security specialist comes in.

This post focuses on the second path: mastering weaknesses and security.

What You Need in General

1. Your Home Lab

Your first lab is your computer.

More specifically, you need to understand how to use your operating system to its full potential.

For this process, switching to Linux is highly recommended, since most security tools are built for it.
If you cannot switch, use virtualization (like VirtualBox or VMware). Using Wine/Proton is not ideal for serious security work.

You must understand:

  • Processes
  • File systems
  • Permissions
  • Networking configuration
  • Logs
  • Package management

If you don’t understand your own machine, you cannot secure others.

2. Programming

By mastering programming, you will be able to:

  • Create, modify, and configure tools
  • Read and understand exploit code
  • Automate repetitive tasks
  • Analyze what can be broken

Python is one of the most practical languages in cybersecurity.
You may also learn JavaScript (especially for web security) or C (for low-level and memory-related topics). It depends on your interests.

Programming is not optional. It gives you control instead of dependency.

3. Networking

Your cyber life depends on two things (besides oxygen and water): electricity and internet. The internet is a massive network. You are reading this through multiple networks right now. If you don’t understand networking, you don’t understand how attacks travel.

Learn:

  • TCP/IP
  • DNS
  • HTTP/HTTPS
  • Ports
  • Routing basics
  • Firewalls

Networking is not a “plus.” It is a foundation.

4. Fundamentals Based on Your Direction

Depending on what you want to focus on, you’ll need deeper fundamentals.

For example:

  • If you’re into web security → understand how the web works (requests, sessions, cookies, authentication).
  • If you’re into system security → understand system calls, memory, and privilege levels.
  • If you’re into low-level security → understand how the OS interacts with hardware.

You don’t need everything at once. But you do need depth in something.

Practice Makes the Difference

Every concept you learn is theoretical until you practice it.

You must:

  • Break things in your lab
  • Set up vulnerable machines
  • Solve CTF challenges
  • Reproduce vulnerabilities

Practice makes knowledge usable.

Bonus

Learn how to use AI tools properly. Prompt engineering can save hours on routine tasks. But don’t let tools replace understanding.

Also, learn how to learn.

Most high-level cybersecurity knowledge exists in:

  • Documentation
  • Books
  • Research papers
  • RFCs
  • Technical blogs

It is rarely explained fully through visuals or short videos.

If you can read deeply and understand technical documentation, you will grow much faster.
