At its core, cybersecurity is about keeping three things safe (often called the CIA triad):

• Confidentiality – making sure sensitive information is only accessed by the right people
• Integrity – ensuring data isn’t altered or tampered with
• Availability – making sure systems and data are accessible when needed

What does cybersecurity protect against?

Cybersecurity defends against threats like:

• Hacking (unauthorized access to systems)
• Malware (malicious software like viruses, ransomware)
• Phishing (tricking people into revealing sensitive info)
• Data breaches (leaking or stealing confidential data)

Where is cybersecurity used?

It’s used everywhere digital systems exist:

• Personal devices (phones, laptops)
• Businesses and banks
• Government systems
• Online services (email, social media, cloud storage)
