Cloud storage makes life easier — until your private files get shared with the wrong person. Misconfigurations, weak passwords, and phishing are still the top causes of data leaks. Let’s fix that.
1. Audit Your Cloud Accounts
- Check who has access to your folders — remove old collaborators.
- Review “shared via link” files and disable public access.
- On Google Drive, use “View details” > “Who has access.”
2. Secure Your Login
- Use strong, unique passwords or better, passkeys.
- Enable two-factor authentication (2FA) on every cloud account.
- Avoid signing in on public Wi-Fi without a VPN.
3. Encrypt Sensitive Files Before Uploading
- Use tools like 7-Zip, VeraCrypt, or Cryptomator to encrypt folders.
- This ensures even if hackers access your drive, your data stays unreadable.
4. Watch for Phishing Links
Many “document-share” emails are fake — double-check the sender’s domain.
Example: “@googledocs-secure.com” ≠ Google Docs.
5. Backups Matter
Cloud ≠ backup. Keep a local encrypted copy of essential files on an external drive.
Final Tip
Treat your cloud like a digital filing cabinet — review it every few months and lock what’s sensitive.
