How to Audit Remote Desktop Connections Effectively

With the increasing trend of remote work and teams spread across different locations, monitoring Remote Desktop Protocol (RDP) connections has never been more vital. Auditing these connections ensures that only the right users are accessing your systems and helps you swiftly identify any unusual activity.

In this guide, you'll find practical methods that range from built-in Windows tools to advanced SIEM solutions and third-party software, all designed to help you effectively track and secure remote desktop access in your environment.

Methods for Auditing Remote Desktop Connections

1. Using Event Viewer

Event Viewer is a handy built-in tool in Windows that lets you check the logs for incoming RDP connections.

• Open Event Viewer:
  • Press Windows + R, type in eventvwr.msc, and hit Enter.
•  Navigate to Remote Desktop Logs:
  • Head over to Applications and Services Logs -> Microsoft -> Windows -> TerminalServices-RemoteConnectionManager -> Operational.
•  Filter Events:
  • Right-click on Operational and choose Filter Current Log.
  • In the filter, enter Event ID 1149 to view successful remote desktop connections.

2. Utilize Security Information and Event Management (SIEM) Tools

• Collect and Analyze Logs: SIEM tools like Splunk, Elastic Stack, or Microsoft Sentinel can gather logs from various sources, including Windows event logs.
• Correlate Events: SIEMs can link remote desktop connection events with other security incidents, such as user activity, network traffic, and threat intelligence feeds.
• Generate Alerts: Set up alerts for suspicious activities, such as:
  • Connections from unusual locations
  • Login attempts from blocked IP addresses
  • Multiple failed login attempts from a single source

3. Consider Third-Party Tools

• Specialized Auditing Tools: There are third-party tools specifically designed for auditing remote desktop connections.
• They may provide features like:
  • Real-time monitoring
  • Session recording
  • User behavior analysis

Additional Tips:

• Restrict Remote Desktop Access: Only permit remote desktop connections from authorized devices and networks.
• Strong Passwords: Implement strong passwords and multi-factor authentication.
• Regularly Review Logs: Make it a habit to review audit logs to spot and investigate any suspicious activity.
• Stay Updated: Ensure your operating system and remote desktop software are up to date with the latest security patches.

Conclusion

Monitoring remote desktop connections is key to maintaining visibility and control over how remote access is handled in your organization. With tools like Event Viewer, SIEM platforms and various third-party solutions at your disposal, you can identify unauthorized access attempts, delve into user activities, and enhance your security measures. By regularly keeping tabs on these connections and following best practices like setting access restrictions and using multi-factor authentication, you can ensure that your remote desktop setup stays secure and compliant.
