In today's changing cybersecurity landscape, securing your Windows Server 2022 Standard is not optional - it's essential. Whether you run a small business or manage an enterprise infrastructure, attackers are constantly looking for vulnerabilities. The question is: Are you fully prepared to defend your server against the most common threats?
In this guide, we will show you the 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 is important
Windows Server 2022 Standard is a robust and modern operating system, but still a favorite target for:
- Ransomware attacks
- Unauthorized remote access
- Theft of login information
- Misconfigured services
- Outdated patches
Without appropriate security measures, sensitive business data could be exposed or costly downtime could occur. Let's take a look at how you can prevent this.
1. keep your server up to date and patched
Use Windows Update Services or WSUS
Always activate automatic updates or set Windows Server Update Services (WSUS) to ensure that you are protected against known vulnerabilities.
According to the CISA unpatched software is one of the most frequently exploited entry points for cyberattacks.
Best Practices:
- Schedule patches outside of business hours
- Prioritize security updates over functional updates
- Test patches in a staging environment first
2. configure Windows Defender and activate ATP
Real-time protection with Microsoft Defender
Windows Server 2022 contains Microsoft Defender Antivirus, an integrated solution with real-time protection against malware.
Steps to strengthen protection:
- Activate Cloud-based protection
- Switch Automatic sample transmission a
- Integrate Microsoft Defender for Endpoint (ATP) for advanced threat protection
Would you like a licensed version of Windows Server 2022 Standard? Make sure that your license supports ATP integrations.
3. secure the Remote Desktop Protocol (RDP)
RDP is a frequent target of attacks
Hackers often target open RDP ports. Secure these by:
- Use of Network Level Authentication (NLA)
- Change of the Standard RDP port (3389)
- Establishment of Multi-factor authentication (MFA)
- Restriction of RDP access through firewall rules and Group policies
4. activate the Windows firewall and create input rules
An incorrectly configured firewall can expose critical services to the Internet.
How to lock them:
- Block all incoming data traffic by default
- Create rules for essential services only
- Log discarded packages for monitoring
- Restrict administrative access by IP
5. set up role-based access control (RBAC)
Restrict access based on the Principle of least rights.
Use RBAC to:
- Assign roles to users instead of assigning admin rights
- Accesses with Event display or PowerShell scripts to monitor and log
- Delete unused user accounts regularly
You can also Active Directory group policies configure for stronger access control.
6. implement secure DNS and SMB protocol settings
Older protocols such as SMBv1 are vulnerable and should be deactivated.
Tips for network backup:
- Deactivate SMBv1
- Use DNS over HTTPS (DoH) or encrypted DNS for better security
- Monitor DNS queries with Windows event logs or third-party tools
Tools like Wireshark and Nmap can help to test DNS and SMB vulnerabilities.
7. carry out regular security audits and backups
Even the best configuration needs checking.
Audit basics:
- Use Windows Security Audit Guidelines
- Activate Object access monitoring for sensitive files
- Create automated Backup schedules (locally and in the cloud)
For secure backups, you should encrypt data and store external replicas.
Conclusion
Securing Windows Server 2022 Standard is an ongoing process - not a one-off setup. From patch management and RDP protection to firewall configuration and role-based access control, every step plays a crucial role in protecting your systems against modern threats.
When setting up or updating your infrastructure, start with a licensed version of Windows Server 2022 Standard, to unlock all security functions.

FAQ
1. is Windows Server 2022 secure by default?
It has strong security features out of the box, but administrators must manually configure advanced protection measures such as RBAC, firewall rules and ATP.
2. which ports should I close on Windows Server 2022?
Close all ports that are not required. Frequently checked ports are RDP (3389), FTP (21), Telnet (23) and NetBIOS (137-139).
3. can I run Antivirus and Windows Defender at the same time?
Yes, but avoid conflicts in real-time monitoring. If you use third-party antivirus software, configure exceptions in both tools to prevent resource problems.
