Your personal data is valuable and should be treated as such. Here’s how to keep it safe:

Be cautious about sharing personal information on social media and other online platforms.

5.2 Use Encryption

Encrypt sensitive data to make it unreadable to unauthorized parties.

5.3 Beware of Public Wi-Fi Risks

Avoid accessing sensitive information while connected to public Wi-Fi networks, as they can be vulnerable to attacks.

6. Safe Online Transactions

Online shopping and banking are convenient but require precautions:

6.1 Shop from Secure Websites

Look for “https://” and a padlock symbol in the address bar before entering payment information.

6.2 Monitor Your Financial Statements

Regularly review your bank and credit card statements for unauthorized transactions.

Use different passwords for different accounts to minimize the impact of a potential breach.

9. Two-Factor Authentication (2FA)

2FA provides an extra layer of security:

Phishing is a common tactic used by cybercriminals:

12.1 Be Skeptical of Emails

Don’t click on links or download attachments from unknown sources.
