How does VPN monitoring work?
VPN monitoring uses Internet Control Message Protocol echo requests, or pings, to determine if a VPN tunnel is available. In typical operation, pings are sent through the VPN tunnel to a peer gateway or a specific destination at the other end of the tunnel. Pings can be sent in preset 10-second intervals for a specific number of attempts. If there is no reply after the preset number of ping attempts, the VPN is assessed as down, and security protocols -- e.g., IPsec -- are cleared. The VPN monitoring device must be set to the VPN-monitor option so that endpoint IP addresses using the VPN tunnel can be monitored. Pings are sent only when there is outgoing traffic and no incoming traffic through the VPN tunnel. The tunnel is deemed active if it detects incoming traffic through the VPN tunnel.

A better approach is to use a tool that monitors network traffic going to and from the internet using a SPAN, mirror port, or network TAP. Once a traffic source is established, you can use a solution like InsightIDR to detect whether RDP is in use on your network. You will need a system that is application-aware, since RDP can run over any network port, so looking for activity on TCP port 3389 alone is not sufficient.
How to check if RDP is running?
One quick check you can do to check for RDP activity is to see whether TCP port 3389 is open on your firewall. While this is not an indication of activity, you should consider shutting it down for all external clients. It is also possible to run RDP over a different port number , so focusing on TCP port 3389 alone is not enough.
Why did nobody check the firewall?
Nobody checked this, and because they had no visibility inside their network, they had no idea systems running RDP were exposed to external clients.
