Schritte zur besseren Sicherheit (Steps to Better Security)

  1. Regelmäßige Updates – Regularly update your operating system, web browser, and other software to ensure you have the latest security patches. These updates help protect against known vulnerabilities that cybercriminals could potentially exploit.
  2. Secure Passwords – Create strong passwords using a combination of uppercase letters, lowercase letters, numbers, and symbols. Change your password regularly, and avoid sharing it with others or writing it down.
  3. Antivirus Software – Install antivirus software on all your devices to protect against malware attacks. Ensure that the software is updated regularly to remain effective against new threats.
  4. Two-Factor Authentication – Implement two-factor authentication (2FA) whenever possible. This added security layer requires users to provide two forms of verification, typically a password and a code sent via text message or email, before accessing an account.
  5. Secure Connections – Use secure connections when accessing sensitive data online. Look for websites with the HTTPS protocol, which encrypts data transmitted between your device and the website.
  6. Be Aware of Phishing Scams – Be cautious of emails, messages, or links that ask for personal information or require you to download attachments. Cybercriminals often use phishing scams to trick users into giving up sensitive data or installing malware on their devices.
