How To Become a Cybersecurity Expert Without Formal Education

Do you think cybersecurity experts have years of formal education or specialized degrees? Very often they don’t!

If you’re determined and willing to learn, you can develop all the necessary skills on your own.

Today, I’ll guide you through key areas you should master and the resources that can help you on this journey. By the end, you’ll see that becoming a cybersecurity expert without formal education is not only possible but also practical.

Start with Linux Fundamentals

Linux is the backbone of cybersecurity. Many servers, security tools, and systems run on Linux, so learning it is non-negotiable.

If you’re new to Linux, don’t worry. Here is a great tutorial on Linux for Ethical Hackers.

Start small. Install a beginner-friendly Linux distribution like Ubuntu on your computer. This will help you get familiar with the environment.

Next, dive into the command line.

Use commands like ls, cd, and cp to navigate and manage files. Understanding permissions is crucial, so practice using chmod and chown.

As you grow comfortable, learn more advanced tools like:

• grep for searching text

• top for monitoring processes

• iptables for managing firewalls.

These tools will give you hands-on experience with the daily tasks of cybersecurity pros.

The key to mastering Linux is consistent practice. Try breaking things on your Linux machine and fixing them. That’s where real learning happens.

Understand Basic Networking

Networking is another pillar of cybersecurity. After all, most cyberattacks happen over networks.

To become an expert, you must understand how data moves between devices.

Start by learning how networks work. Focus on concepts like IP addresses, DNS, and TCP/IP. These are the building blocks of the internet.

Here is a great YouTube playlist with short videos on basic networking concepts.

Use tools like Wireshark to analyze network traffic. Wireshark lets you see data packets moving through a network.

For example, if someone uploads a file, you can watch that file travel across the network, packet by packet. It’s an incredible way to understand real-world networking in action.

Practice setting up small networks at home. Connect devices, configure a router, and use ping commands to test connectivity.

As you learn, you’ll begin to see how everything fits together.

Practice on TryHackMe

Once you understand Linux and networking, it’s time to get your hands dirty with practical labs.

That’s where platforms like TryHackMe come in. TryHackMe offers guided labs for beginners and advanced users. Each lab takes you step by step through real-world scenarios.

For example, one challenge might involve identifying a vulnerable server. You’ll analyze the server, exploit a weakness, and secure it against future attacks.

Another lab might ask you to break into a website using common vulnerabilities. These exercises are both fun and incredibly educational.

TryHackMe has structured learning paths, like the “Pre-Security” and “Complete Beginner”. They help you go from zero knowledge to a strong foundation. You can even specialize by taking the “Penetration Testing” or “Defensive Security” paths.

Start with the free modules, and as you gain confidence, consider a paid subscription for more advanced content.

Explore HackTheBox

If TryHackMe is like a classroom, HackTheBox is like a playground.

It’s a platform designed for cybersecurity enthusiasts to test their skills on real systems. Here, you’ll face tougher challenges compared to TryHackMe. The focus is on problem-solving and creativity.

On HackTheBox, you’ll encounter “machines,” which are virtual systems with hidden vulnerabilities. Your job is to exploit these vulnerabilities and gain access to the machine.

For example, a challenge might involve finding an outdated software version and using an exploit to break in.

What makes HackTheBox unique is its focus on the “capture the flag” (CTF) format. In these challenges, your goal is to find hidden strings or “flags” within a system. The flags prove that you’ve successfully hacked the machine.

HackTheBox is not beginner-friendly, so start with TryHackMe before jumping into HackTheBox. Once you feel ready, HackTheBox will push you to think outside the box and refine your skills even further.

Online Communities

Cybersecurity isn’t a solo journey. You’ll learn faster and stay motivated by joining communities of like-minded individuals.

One great place to start is Reddit’s Hacking Tutorials group. It is a community full of professionals and beginners eager to help and share knowledge.

In these communities, people often share insights about the latest tools, vulnerabilities, and techniques. You can ask questions, share your progress, and connect with other professionals.

Engaging with others exposes you to new ideas and keeps you updated on cybersecurity trends.

Conclusion

Becoming a cybersecurity expert without formal education is entirely possible. The path requires dedication, but the resources are out there.

Start with Linux and learn its fundamentals. Once you’re comfortable with Linux, dive into basic networking concepts. Along the way, join online communities to share your journey and learn from others.

Every expert started as a beginner. You don’t need a fancy degree to succeed. You need curiosity, persistence, and a willingness to learn. Take one step at a time, and before you know it, you’ll be the one helping others break into this field. Start today.
