VPS Security: How to Secure a Windows Server

This article explains how to secure a Windows Server. First, install all Windows updates and patches to close known vulnerabilities. Next, change the default RDP port and restrict RDP access to trusted IP addresses through Windows Firewall. Then create strong passwords. After that, configure the firewall to allow only necessary ports and block unnecessary ones, and install Windows Server antivirus software, cleaning up any suspicious files. Finally, back up important data regularly to local or external storage, or consider a remote backup service.

Why Windows Server Security Matters

Unsecured servers are vulnerable to malware, brute-force attacks, ransomware, and data breaches. By improving server security, you ensure:

  • Protection of sensitive business and customer data
  • Stable server performance
  • Reduced risk of downtime
  • Compliance with security standards

Steps to Secure Windows Server

Step 1: Install Windows Updates and Patches

Keeping your operating system up to date is the foundation of server protection.

  1. On your Windows Server, click the Search bar.
  2. Type Windows Update and open the Windows Update settings.
  3. Click Check for updates.
  4. Install all available updates.
  5. Restart your server if prompted.
    install windows updates
    Regularly applying updates strengthens cloud server security by closing known vulnerabilities.

Step 2: Change RDP Port and Restrict Access

Remote Desktop Protocol (RDP) is often targeted by hackers. Changing the default port and restricting access improve VPS security.

2.1 Change Default RDP Port

  1. Refer to How to Change Windows RDP Port.
  2. Use a non-standard RDP port number.

2.2 Restrict RDP to Trusted IPs

  1. Open the Firewall and Locate the RDP Rule
  • Press Win + R, type wf.msc, and press Enter to open Windows Defender Firewall with Advanced Security.
  • In the left pane, click Inbound Rules, then scroll to find Remote Desktop (TCP-In).
  • Right-click the rule and select Properties.

  1. Configure Allowed IP Addresses
  • In the rule’s Properties window, switch to the Scope tab.
  • Under Remote IP address, change the option from Any IP address to These IP addresses.
  • Click Add and enter the IP addresses or IP ranges you want to allow RDP access from.
    • You can add a single IP (e.g., 203.0.113.10) or a range (e.g., 203.0.113.1 – 203.0.113.50).
  • Click OK to save each entry, then click OK again to apply the rule.

This prevents unauthorized access and boosts Windows Server security.

Step 3: Create Strong Passwords

Weak passwords are one of the biggest threats to server protection.

  1. Use a password with at least 12 characters, including uppercase, lowercase, numbers, and symbols.
  2. Avoid reusing passwords.
  3. Change the Administrator password every 60–90 days.

Step 4: Firewall and Port Control

Firewalls are a key part of Windows Server security.

  1. Open Windows Defender Firewall from the Control Panel.
  2. Allow only the ports you need (such as HTTP/HTTPS for web servers).
  3. Block unnecessary ports to reduce risks.

If suspicious files are detected, click Clean up to remove them immediately.

Step 6: Backup Data Periodically

Backups are an essential layer of server protection.

  1. Regularly back up your important files to your local PC or external storage.
  2. Consider remote backup services for cloud server security.
  3. Database Mart provides Remote Data Center Backup Service, which automatically stores selected files (such as C:\ drive data) in secure remote servers.

Contact Database Mart support if you want to enable this server protection service.

Conclusion

By above these six steps, you can significantly improve VPS security, strengthen Windows Server security, and ensure your server is fully protected from threats.

Taking these precautions ensures your cloud server security and keeps your system safe from attacks.
