A cyber security learning roadmap from scratch for beginners starts with mastering networking and operating systems, moves into Linux and core security concepts, builds a legal home lab, practices blue team skills with log analysis and SIEM, earns the Security+ certificate, then assembles a portfolio. These seven stages take roughly nine to twelve months with regular practice and always rest on lawful defensive work.
- Networking and Linux come first, because security is built on understanding how systems work
- Each stage leaves one tangible result, from lab notes to writeups, as portfolio material
- All practice happens in your own environment or on official platforms, always within the law
What You Need
- A laptop with at least 8 GB of RAM to run one or two virtual machines at once
- A stable internet connection to access materials, documentation, and online practice platforms
