Step-by-Step Guide: How to Become a Cyber Security Expert With No Experience

Step 1: Understand the Basics of Cyber Security

Start by familiarizing yourself with:

• What cyber security is

• Types of cyberattacks (phishing, malware, ransomware, DDoS, etc.)

• How hackers think

• What security experts do

A basic understanding will give you confidence and direction in your learning journey.

Step 2: Learn the Fundamentals of Networking

Networking is the backbone of Cyber Security. Without knowing how networks operate, you can’t protect them.

Focus on topics such as:

• IP Address & Subnetting

• DNS & DHCP

• VPN & Firewalls

• TCP/IP & OSI Model

• Client-server architecture

Even if you’re from a non-IT background, these concepts are easy to learn with proper guidance.

Step 3: Get Comfortable With Linux

Most cyber security tools run on Linux systems, especially Kali Linux.

Learn:

• Basic terminal commands

• File permissions

• Process management

• Installing and running tools

With a few days of practice, Linux becomes simple and powerful.

Step 4: Start Learning Essential Cyber Security Tools

These tools help you understand real-world security testing:

• Nmap – network scanning

• Wireshark – packet analysis

• Burp Suite – web security testing

• Metasploit – penetration testing

• Kali Linux Toolkit

Learning how to use these tools is a major step toward becoming a skilled ethical hacker or cyber security analyst.

Step 5: Learn Basic Scripting (Useful but Optional)

You don’t need to be a programmer, but basic scripting helps in automation.

Recommended:

• Python

• Bash scripting

• HTML/CSS understanding for web vulnerabilities

A little coding knowledge can set you apart from other beginners.

Step 6: Practice in Real Cyber Security Labs

Cyber Security is a hands-on field — you must practice.

Use safe, legal platforms such as:

• TryHackMe

• Hack The Box

• OverTheWire

• DVWA (Damn Vulnerable Web App)

These platforms simulate real hacking environments and help you improve your problem-solving skills.

Step 7: Earn a Recognized Certification

Certifications validate your skills and increase your chances of landing a job.

Beginner-friendly certifications:

• CEH – Certified Ethical Hacker

• CompTIA Security+

• Cisco CCNA Security

• Livewire Cyber Security Certification (Industry-recognized)

Even one certification can significantly boost your resume.

Step 8: Build a Simple Cyber Security Portfolio

A good portfolio can fast-track your hiring process.

Include:

• Penetration testing reports

• Analysis of mock security incidents

• CTF (Capture the Flag) write-ups

• Scripts or tools you’ve created

• Documentation of your learning journey

A portfolio shows that you can apply your knowledge practically.

Step 9: Apply for Internships & Entry-Level Roles

Once you have the fundamentals, some hands-on practice, and a certificate, you can start applying for:

• Junior Cyber Security Analyst

• SOC Analyst (Security Operations Center)

• Network Security Trainee

• Ethical Hacking Intern

• Technical Support (Cyber track)

These entry-level roles help you gain real experience and move toward becoming a Cyber Security expert.
