What is Cybersecurity?

Cybersecurity refers to the practices and technologies designed to protect systems, networks, and data from unauthorized access, attacks, or damage. In today’s digital world, staying safe online is just as important as being safe in real life.

Key Goals:

• Protect personal and sensitive data

• Prevent online fraud, theft, and identity loss

• Maintain secure communication and collaboration

Types of Cyber Threats

1. Phishing: Fake emails or messages designed to steal your data

2. Malware: Malicious software like viruses, ransomware

3. Identity Theft: Stealing personal info to pretend to be someone else

4. Hacking: Unauthorized access to systems

5. Cyberbullying: Using online platforms to harass others

🛡️ Tip: Never click on unknown links or download files from untrusted sources.

How to Stay Safe Online

Good practices for digital safety:
