What is cyber security?

Cyber security is the practice of protecting computers, networks, systems, and data from digital attacks such as hacking, malware, phishing, and data breaches.

Why is cyber security important in today’s digital world?

In today’s digital world, almost everything is connected to the internet—personal data, banking, businesses, and government systems. This connectivity makes cyber security essential because cyber attacks can lead to:

• Financial loss
• Identity theft
• Data leaks
• Disruption of essential services

The rapid growth of online services, cloud computing, and remote work has increased the frequency and sophistication of cyber threats, making robust security measures critical for reducing risk.

How cyber security helps

• Protects personal and sensitive information
• Prevents unauthorized access to systems
• Ensures safe online transactions
• Maintains trust in digital platforms
