Cybersecurity refers to the practice of protecting computer systems, networks, and digital information from unauthorized access, theft, or damage by cyber threats and attacks. It encompasses the measures and services taken to safeguard an organization's technology infrastructure, data, and systems from these evolving cyber threats. Cybersecurity is a critical concern for businesses of all sizes, as they face increasing risks of cyberattacks that can have severe consequences for their operations, finances, and reputation.

Cyber security is about protecting computers, networks, and data from criminals who want to steal information, cause damage, or mess with systems. It involves using technology, tools, and good practices to keep information safe and secure from cyber attacks.
Three Actionable Steps to Get into Cyber Security
(1) Learn the Basics of Cyber Security and IT
Action: Start with online courses, YouTube tutorials, or websites like Codecademy, Coursera, and Khan Academy that offer introductory courses in cyber security, networking, and computer science.
Benefit: Understanding the fundamentals will give you a strong foundation and help you decide which areas of cyber security interest you the most.
(2) Gain Practical Experience
Action: Participate in cyber security challenges and competitions such as Capture the Flag (CTF) events on platforms like Hack The Box, TryHackMe, or CTFtime.
Benefit: Hands-on experience will help you apply what you've learned and develop problem-solving skills. It’s also a great way to build your resume and network with others in the field.
(3) Get Certifications and Join Communities
Action: Work towards entry-level certifications like CompTIA Security+ or Certified Ethical Hacker (CEH). Additionally, join cyber security forums, groups, and local meetups to stay updated on the latest trends and connect with professionals.
Benefit: Certifications validate your skills and knowledge to potential employers. Being active in communities can provide support, advice, and job opportunities.
Additional Tips
Stay Curious and Keep Learning: Cyber security is a constantly evolving field. Always be eager to learn new things and stay updated with the latest developments.
Build a Home Lab: Set up a home lab with old computers or virtual machines to practice and experiment in a safe environment.
Read and Follow Experts: Follow cyber security blogs, podcasts, and social media accounts of industry experts to gain insights and stay informed about new threats and solutions.

"Cyber" is the simplified version of "Cybernetics", coined in a book published in 1948, how systems within machines and animals regulate themselves and interact w/ their environment, however it is now more about computers and digital communication. So cybersecurity would be primarily addressing the security of those systems.
If you want to get a big picture of what that means specifically, the Career Options" section of https://niccs.cisa.gov/education-training/cybersecurity-students would be a good place to start.
You can also check UK's National Cyber Security Centre (NCSC) at https://www.ncsc.gov.uk/section/education-skills/schools which might have better resources closer to home.
Good luck!

If we eliminate all the hype, buzzwords, and misinformation, Cyber Security is simply the implementation of Security on or relating to technology.
The root principle of security, is the balance between accessibility and security. I say balance because you can't have both. If something is secure, it is not accessible, and if it is accessible it is not secure.
For example, if you had information on your cellphone and wanted it completely secure. Take the cell phone, put it in a furnace and melt it down completely, and while it is still heated to a malleable state compress it into a ball or wafer, then break and distribute the pieces around the globe. The information is now secured and nobody can get to it.
To achieve balance, information security and by extension cyber security has at its core 3 tenets which represent the goals or points of assurance.
This is the CIA triad: Confidentiality, Integrity, and Availability
Confidentiality: Information is protected from being viewed by those it is not intended for.
Integrity: Information is protected from being modified, or changed by those who are not supposed to change it.
Availability: Information is available to those who are supposed to have access to it, when they want to have access to it.
Those 3 principles are leveraged alone or in some combination to provide security to a system, device, application, web site, etc.
How do you keep information confidential? Encryption
How do you maintain integrity? Track and account for changes
How do you maintain availability? Backups, fail over, shields and defensive measures
The Cyber Security industry is about implementing measures towards ensuring the CIA principles within the available budget.
This gets into Risk Management which is essentially a cost comparison between how much you spend on fixing a point of vulnerability versus the likely-hood that vulnerability will be exploited, and how much that being exploited will cost the organization
If you can wrap your head around these concepts as I've explained them and adopt a mindset to apply that to your view of cyber security, you should find it pretty easy to learn and explore.
