How to Secure Windows Server 2022 Standard Against Common Threats

In today’s evolving cybersecurity landscape, securing your Windows Server 2022 Standard is not optional—it’s essential. Whether you’re running a small business or managing enterprise infrastructure, attackers are constantly probing for vulnerabilities. The question is: Are you fully prepared to defend your server against the most common threats?

In this guide, we’ll walk you through key security practices, tools, and configurations you should implement to harden your Windows Server 2022 and protect your organization’s data and uptime.

Why Securing Windows Server 2022 Standard Matters

Windows Server 2022 Standard is a robust and modern operating system, but it’s still a prime target for:

  • Ransomware attacks

  • Unauthorized remote access

  • Credential theft

  • Misconfigured services

  • Outdated patching

Without the proper security measures, you could expose sensitive business data or suffer costly downtime. Let’s explore how to prevent that.

1. Keep Your Server Updated and Patched

Use Windows Update Services or WSUS

Always enable automatic updates or deploy Windows Server Update Services (WSUS) to ensure you’re protected from known vulnerabilities.

According to CISA, unpatched software is one of the most exploited entry points for cyberattacks.

Best Practices:

  • Schedule patching during off-hours

  • Prioritize security updates over feature updates

  • Test patches in a staging environment first

2. Configure Windows Defender and Enable ATP

Real-Time Protection with Microsoft Defender

Windows Server 2022 includes Microsoft Defender Antivirus, a built-in solution offering real-time malware protection.

Steps to enhance protection:

  • Enable Cloud-Delivered Protection

  • Turn on Automatic Sample Submission

  • Integrate Microsoft Defender for Endpoint (ATP) for advanced threat protection

3. Harden Remote Desktop Protocol (RDP)

RDP is a Common Attack Vector

Hackers often target open RDP ports. Secure it by:

  • Using Network Level Authentication (NLA)

  • Changing the default RDP port (3389)

  • Setting up Multi-Factor Authentication (MFA)

  • Restricting RDP access using firewall rules and Group Policy

4. Enable Windows Firewall and Create Inbound Rules

A misconfigured firewall can expose critical services to the internet.

To lock it down:

  • Block all inbound traffic by default

  • Create rules only for essential services

  • Log dropped packets for monitoring

  • Limit administrative access by IP

5. Set Up Role-Based Access Control (RBAC)

Limit access based on the principle of least privilege.

Use RBAC to:

  • Assign roles to users instead of giving admin rights

  • Monitor and audit access using Event Viewer or PowerShell scripts

  • Revoke unused user accounts regularly

You can also configure Active Directory Group Policies for stronger access control.

6. Implement Secure DNS and SMB Protocol Settings

Older protocols like SMBv1 are vulnerable and should be disabled.

Network hardening tips:

  • Disable SMBv1

  • Use DNS over HTTPS (DoH) or encrypted DNS for better security

  • Monitor DNS queries using Windows Event Logs or third-party tools

Tools like Wireshark and Nmap can help test DNS and SMB vulnerabilities.

7. Perform Regular Security Audits and Backups

Even the best setups need verification.

Audit essentials:

  • Use Windows Security Audit Policies

  • Enable Object Access Auditing for sensitive files

  • Create automated backup schedules (both local and cloud)

For secure backups, consider encrypting data and storing offsite replicas.

Conclusion

Securing Windows Server 2022 Standard is an ongoing process—not a one-time setup. From patch management and RDP hardening to firewall configuration and role-based access, every step plays a vital role in defending your systems against modern threats.

If you’re setting up or upgrading your infrastructure, start with a licensed version of Windows Server 2022 Standard to unlock full security capabilities.

FAQ

1. Is Windows Server 2022 secure by default?

It has strong out-of-the-box security features, but administrators must manually configure advanced protections like RBAC, firewall rules, and ATP.

2. What ports should I close on Windows Server 2022?

Close all non-essential ports. Common ones to review include RDP (3389), FTP (21), Telnet (23), and NetBIOS (137-139).

3. Can I run antivirus and Windows Defender together?

You can, but avoid real-time scanning conflicts. If using third-party antivirus, configure exclusions in both tools to prevent resource issues.
