🧭 Step-by-Step Cybersecurity Roadmap
1. Use Strong and Unique Passwords
Use a password manager like Bitwarden or Proton Pass. Never reuse passwords across different sites.
2. Enable Two-Factor Authentication (2FA)
Use an authenticator app such as Authy or Google Authenticator instead of relying on SMS codes.
3. Keep Your Software Updated
Always install security updates for your operating system, apps, and devices as soon as they become available.
4. Protect Your Devices
Install antivirus software like Malwarebytes, avoid downloading unknown apps, and activate device encryption.
5. Secure Your Internet Connection
Use a secure DNS provider like Cloudflare (1.1.1.1), enable WPA3 on your router, and avoid using public Wi-Fi for sensitive tasks.
6. Be Privacy-Aware on Social Media
Don’t overshare personal information, use private profiles when possible, and review privacy settings regularly.
