VPS Security: 10 Essential Steps for 2026

Step 1: Strong Password

Use 16+ character passwords with mixed case, numbers, and symbols.

Never use common words or personal information.

Generate passwords with a password manager like Bitwarden or 1Password.

Step 2: Change Default RDP Port

Default RDP port is 3389. Bots scan this port specifically.

Change to a random high port (40000-65535) in Windows Registry.

This dramatically reduces automated attack attempts.

Step 3: Enable Windows Firewall

Windows Server 2022 includes a powerful firewall. Enable it.

Allow only specific ports needed (RDP, HTTP, HTTPS).

Block all other inbound traffic.

Step 4: Install Updates Regularly

Windows Updates fix security vulnerabilities.

Set Windows Update to install automatically.

Restart your VPS monthly to apply updates.

Step 5: Use Antivirus

Windows Defender is built-in and free.

Keep it enabled and updated.

For higher security, consider Malwarebytes or Bitdefender.

Step 6: Disable Unused Services

Windows Server runs many services by default.

Disable services you do not use (Print Spooler, etc.).

Fewer services = smaller attack surface.

Step 7: Limit Administrator Accounts

Create a non-admin user for daily use.

Only use Administrator when needed.

Disable the default Administrator account if possible.

Step 8: Enable Two-Factor Authentication

Add 2FA to RDP using DUO or similar.

Even if password is stolen, 2FA blocks unauthorized access.

Step 9: Backup Regularly

Use Windows Server Backup or third-party tools.

Backup weekly to external storage.

Test restore process monthly.

Step 10: Monitor Logs

Windows Event Viewer shows login attempts.

Review logs weekly for suspicious activity.

Failed login attempts indicate attack attempts.
