As with all industry fields, you should have a practical approach towards cybersecurity. Use the CISM/CISSP study tools you can find for free. You must learn all the important concepts of cybersecurity, networking and data communication, including Networking (TCP/IP/switching/routing/protocols,etc.), System Administration (Windows/Linux/Active Directory/hardening,etc).
I found Daniel Miessler’s post on developing a career in cybersecurity really interesting and useful on this topic.
Podcasts are also useful. Consider Security Now, Paul’s Security Weekly, and Down the Security Rabbit Hole for starters.
Set your goals
Cybersecurity is a vast field. A lot of people mix up different cybersecurity and information security roles. If you want to make a career in the IT security industry, you should have more clarity on your goals.
