What is Cybersecurity?
Cybersecurity is the practice of protecting devices, accounts, information and systems from misuse, damage or unauthorised access.
101 takeaway: Start by understanding the purpose of the system before memorising technical vocabulary.
Why it matters
Strong security usually comes from layers: unique passwords, multi-factor authentication, updates, backups and careful decision-making.
Learning the foundation helps you ask better questions, recognise limitations and make more informed decisions.
A practical way to begin
Choose one small, low-risk task connected to this topic. Observe the result, write down what worked and identify one thing to improve. Practical learning turns a definition into usable understanding.
