- Phishing emails and fake websites

Protecting your privacy and devices helps you avoid financial losses and keeps your personal information secure.
Basic Internet Safety Rules
Use Strong and Unique Passwords
Create passwords that:
- Contain at least 12 characters
- Include uppercase and lowercase letters, numbers, and special characters
- Avoid personal information such as names or birthdays
- Are unique for each account
Consider using a password manager to generate and securely store your passwords.
Enable Two-Factor Authentication (2FA)
Whenever possible, activate two-factor authentication.
This adds an extra layer of security by requiring a second verification step, such as:
- An authentication app
- A security key
- A one-time SMS code
Even if your password is compromised, attackers will have difficulty accessing your account.
Keep Your Software Updated
Regularly update:
- Operating systems
- Web browsers
- Applications and plugins
- Antivirus software
Updates often include security patches that protect against newly discovered vulnerabilities.
Be Careful with Links and Attachments
Do not click links or download attachments from unknown or suspicious sources.
Before opening a link:
- Check the sender’s email address
- Verify the website address carefully
- Look for spelling mistakes or unusual domain names
If you’re unsure, contact the organization directly using official contact information.
Safe Online Banking and Payments
When accessing your bank account or making online payments:
- Use secure and trusted networks
- Avoid public Wi-Fi whenever possible
- Verify that the website address starts with https://
- Look for the padlock icon in your browser’s address bar
- Never share verification codes or passwords
Use trusted payment methods such as:

- Secure payment gateways
Protecting Personal Information
Only share personal information when absolutely necessary.
Avoid publishing sensitive details such as:
- Home address
- Phone number
- Personal identification numbers

Protecting Children Online
Parents and guardians should actively support children in using the internet safely.
Recommended practices include:
