Cyber security is one of the most exciting and in-demand career fields today. If you’re curious about how to start your journey in cyber security, this blog is for you. I’ll share my personal perspective, the learning path I followed, and tips that can help you break into this growing industry — even if you’re starting from scratch.

Why Choose Cyber Security in 2025?

Cyber threats are increasing fast — from data breaches to ransomware and phishing. That means more companies are hiring people who can protect systems, data, and networks.

Whether you want to work as a penetration tester, SOC analyst, ethical hacker, or cyber forensic expert, there’s a career path for everyone.

My Motivation to Join Cyber Security

I started with a love for computers and solving problems. I didn’t know how hacking or network security worked, but I was curious. I kept asking questions like:

• How do hackers break into systems?

• What can we do to stop them?

• Is it legal to be a hacker?

These questions led me to explore blogs, YouTube videos, and eventually, certified courses and hands-on labs. That’s when I knew cyber security was my path.

How to Get Started in Cyber Security — Step-by-Step Guide

Let me walk you through a beginner-friendly learning roadmap based on my experience.

Step 1: Understand the Basics of Cyber Security

Start by learning what cyber security is, including:

• What is a cyber threat?

• What are vulnerabilities and exploits?

• The difference between black hat, white hat, and grey hat hackers

• Introduction to CIA Triad: Confidentiality, Integrity, Availability

You can begin by watching beginner videos on YouTube or reading from trusted sources like:

• Cybrary

• Coursera

• WebAsha’s Cyber Security Courses

Step 2: Learn Networking and Operating Systems

To understand how attacks happen, you must know how computers and networks communicate.

✅ Learn Networking Basics:

• IP addresses, TCP/IP, Subnetting

• DNS, DHCP, HTTP/HTTPS

• OSI Model

✅ Master Operating Systems:

• Linux (very important in cyber security)

• Windows (understanding logs, users, processes)

Free tools: Cisco Packet Tracer, Wireshark, VirtualBox (for virtual labs)

Step 3: Learn About Common Cyber Threats

Familiarize yourself with types of attacks:

Knowing these helps you think like a hacker and later defend against them.

Step 4: Practice in Safe Labs

Now comes the fun part: Hands-on learning!

Start with safe environments like:

• TryHackMe – Beginner-friendly hacking labs

• Hack The Box – For intermediate and advanced levels

• WebAsha Labs – Real-world scenarios for certification prep

Install a Kali Linux virtual machine and start practicing tools like:

• Nmap

• Burp Suite

• Wireshark

• Metasploit

Step 5: Choose a Specialization

Cyber Security is vast. Once you’ve built the foundation, choose what excites you most:

Step 6: Get Certified

Certifications prove your skills to employers. Here are great ones to begin with:

• CompTIA Security+ (Best beginner cert)

• CEH – Certified Ethical Hacker

• OSCP – Offensive Security Certified Professional (Advanced)

• WebAsha Certified Cyber Security Analyst

Each cert opens doors to better jobs and deeper learning.

Step 7: Join the Community

Connect with others! Follow these platforms:

• LinkedIn (connect with professionals)

• Reddit r/cybersecurity

• Discord cyber security servers

• Local meetups, hackathons, and CTFs

Ask questions, join discussions, and build a network.

Step 8: Build a Portfolio

Start documenting your journey:

• Share what you learn on GitHub

• Write blogs or record YouTube tutorials

• Complete capture-the-flag (CTF) challenges and post walkthroughs

This proves you’re learning and helps land internships or jobs.

Conclusion: Is Cyber Security for You?

If you’re someone who loves to solve puzzles, think logically, stay curious, and always ask “how does this work?”—then yes, cyber security is for you.

You don’t need to be a coding genius. You just need:

• Dedication

• Willingness to learn

• Practice, not just theory

I started from zero. And if I can do it, so can you.

FAQs

What is the first step to start learning cyber security?

The first step is to learn the basics — including networking, operating systems (especially Linux), and fundamental security concepts like the CIA Triad.

Do I need a computer science degree for cyber security?

No, a degree helps but is not required. Many professionals enter with certifications, self-study, and hands-on labs.

What are the best free resources to learn cyber security?

TryHackMe, Cybrary, and WebAsha’s beginner modules are great places to start learning cyber security for free.

Which certification should beginners go for in cyber security?
