Starting a SysAdmin/Networking degree (ASIR) in September — what would you do if you had to start cybersecurity from scratch today?
Hi everyone,
I want to get into cybersecurity from scratch and I’d really appreciate advice from people with real-world experience in the field.
In September I’ll be starting a vocational degree in Systems and Network Administration (ASIR) in Spain, and my mid-term goal is to specialize in cybersecurity (not sure yet if red team, blue team, or something more general).
I don’t have professional experience yet, but I’m highly motivated and ready to put in consistent daily effort. I want to use the months before starting my degree to build a solid foundation so I don’t feel lost later.
The problem is that there’s too much information online, and I’m starting to feel overwhelmed without a clear path.
I’d really appreciate guidance on things like:
- If you were in my position, what would your exact starting roadmap look like?
- What should I prioritize first: networking, Linux, scripting (Python/Bash), security fundamentals…?
- What beginner skills actually make a difference early on?
- Truly valuable free resources (not just generic lists)
- Hands-on platforms like TryHackMe or Hack The Box — when should I start using them?
- Common beginner mistakes to avoid
- How I can align what I’ll learn in my degree with a cybersecurity-focused path
I’d also love to hear what you personally did when you started and what you would do differently if you could go back.
My goal is not just to “try it out”, but to take it seriously and build a strong long-term foundation.
Any roadmap, advice, or personal experience would be greatly appreciated 🙌
Thanks
