Practical Tips for Personal Cybersecurity

1. Use Strong and Unique Passwords: Always use strong passwords that combine uppercase and lowercase letters, numbers, and special characters. Avoid using easily guessable information, such as birthdays or names. Additionally, don’t reuse the same password across multiple sites. A password manager can help you keep track of different passwords securely.
2. Enable Two-Factor Authentication (2FA): Two-factor authentication adds an extra layer of security to your online accounts. Even if someone manages to steal your password, they won't be able to log in without the second factor (like a code sent to your phone or an app like Google Authenticator). Always enable 2FA wherever possible.
3. Be Wary of Phishing Attempts: Never click on links or download attachments from unknown or suspicious emails. If you receive an email claiming to be from your bank, email provider, or other important service, always verify its legitimacy by contacting the company directly via their official website or phone number.
4. Install Antivirus and Anti-Malware Software: Ensure that you have antivirus and anti-malware software installed on all your devices. Keep the software updated to detect and prevent new types of threats. Many devices come with basic security tools, but you may want to invest in more robust solutions for better protection.
