Cyber security is one of the fastest-growing fields in tech, yet most beginners make the same mistake: they jump straight to hacking tools without understanding the fundamentals.

Here is the order that actually works:

  1. Computer fundamentals — operating systems, file systems, the command line, Windows administration and Linux basics.
  2. Networking — IP addressing, DNS, DHCP, routing, TCP/IP, firewalls and VPNs. Networking is the foundation of security; without it, everything else is harder.
  3. Linux — most security tooling runs on Linux: file permissions, user management, bash, package management and network utilities.
  4. Security fundamentals — the CIA triad, risk management, malware analysis, social engineering, web security and vulnerability management.
  5. Hands-on practice — build a home lab with virtual machines, Windows Server, Active Directory and log analysis. Practice only in legal lab environments.
  6. Certifications — CompTIA Security+, Google Cybersecurity Certificate, Cisco CyberOps, CEH. They validate knowledge; they do not replace practical skill.
  7. Portfolio — lab reports, vulnerability assessments, write-ups. A strong portfolio often lands the interview before the CV does.

The traps to avoid: skipping networking, learning tools before concepts, avoiding hands-on work, and chasing too many certifications at once.

I put together a fuller breakdown with each step explained and the mistakes beginners make at every stage:
