Restrict RDP Access By IP Address

Remote Desktop Protocol (RDP) is an essential tool for server and workstation management, enabling users to access their systems from anywhere with an internet connection. However, it’s crucial to ensure that RDP access is restricted to authorized users and IP addresses, as unrestricted access can lead to potential security breaches that can compromise sensitive information and data. One of the most effective ways to achieve this is by restricting RDP access by IP address, which allows you to control who can connect to your system remotely.

By restricting RDP access to authorized IP addresses, you can significantly reduce the risk of unauthorized access to your system, which is crucial for businesses and organizations that handle sensitive data. It also minimizes the chances of your system being compromised. Unauthorized access can have devastating consequences, from data theft to system damage and reputational harm.

Therefore, it’s essential to take proactive steps to secure your system, and restricting RDP access by IP address is an effective way to do so. In this blog post, we’ll discuss how you can create and edit IP restrictions in Windows Firewall with Advanced Security, as well as the benefits and risks of not restricting RDP access and best practices for RDP security.

Creating Your IP Restrictions

To restrict RDP access by IP address, you need to create a firewall rule that only allows traffic from specific IP addresses. The following steps will guide you on how to create your IP restrictions:

  • Log in to your server with administrative credentials to create IP restrictions.
  • Open the Windows Firewall with Advanced Security by clicking on the Start button and typing “Windows Firewall with Advanced Security” in the search bar. To launch the app, click on it.
  • On the left side of the screen, select “Inbound Rules”.
  • Create a new inbound rule by clicking on “New Rule” located on the right-hand side of the screen.
  • Select “Custom” and click “Next” in the New Inbound Rule Wizard.
  • Choose “All Programs” and click “Next” to apply the rule to all programs.
  • Under “Protocol type,” select “TCP” and enter port number 3389, which is the default port used for RDP.
  • Under “Remote IP address” choose “These IP addresses”.
  • Click “Add” and enter the IP addresses you want to allow, one at a time.
  • Click “Next” and choose “Allow the connection.”
  • Finally, give the rule a name that you can easily remember and click “Finish” to save it.

By following these steps, you can restrict RDP access by IP address and ensure that only authorized users with valid credentials and approved IP addresses can connect remotely to your server or workstation.

Benefits of Restricting RDP Access by IP Address

There are several benefits to restricting RDP access by IP address, which include:

  1. Enhanced Security: Limiting the number of machines that can connect to your server by restricting RDP access to specific IP addresses helps to reduce the risk of unauthorized access by hackers, malware, and other malicious actors. This measure also safeguards your server from attacks and cyber threats.
  1. Improved Access Monitoring: Restricting RDP access by IP address makes it easier to monitor who is accessing your server. By keeping track of IP addresses, you can identify any suspicious activity or unauthorized access.
  1. Compliance: By restricting RDP access to specific IP addresses, organizations can better comply with regulatory requirements such as GDPR and HIPAA, which mandate technical measures to protect sensitive information.
  1. Better Resource Management: Restricting RDP access to specific IP addresses ensures that only authorized personnel can access resources, helping to prevent overutilization and reduce network congestion.

Best Practices for Securing RDP

Apart from restricting RDP access by IP address, there are several best practices that you can follow to enhance RDP security. These include:

  1. Implement Two-Factor Authentication: Using two-factor authentication can provide an additional layer of security by requiring a second authentication factor, such as a text message or biometric authentication, in addition to a username and password.
  2. Use Strong Passwords: Strong passwords that are at least 8–10 characters long and contain a combination of uppercase and lowercase letters, numbers, and special characters can make it difficult for hackers to gain unauthorized access.
  1. Regularly Update Your Software: Regularly updating your software, including your operating system and firewall, can help protect your server from known vulnerabilities and security risks.
  1. Monitor Your Server Logs: Monitoring your server logs can help you identify any suspicious activity or unauthorized access attempts. You can use tools such as Log Parser to analyze your logs and identify any anomalies. By analyzing your logs, you can identify attempts to bypass your security measures and take corrective action.

By following these best practices, you can reduce the risk of unauthorized access to your RDP connection and minimize the chances of your system being compromised.


It is imperative for organizations to implement the practice of limiting RDP access based on IP address. This security measure can provide protection to sensitive data, thwart cyberattacks and ensure adherence to data protection regulations. To further augment the security of the server and minimize the risk of cyber threats, it is important to adopt the best practices for RDP security. Regular monitoring of server logs and keeping the IP restrictions current can help ensure that only authorized personnel can access the resources.
