An ideal and hardened approach to secure the connection is thru a Virtual Private Network (VPN).
VPN sets up a secure tunnel between your remote location and your office network. This will encrypt the connection and prevent outsiders from logging in using a remote desktop to your work computer.
Suppose you are connecting to your work computer or a terminal server remotely and not familiar with VPN. Please get in touch with your administrator to review and secure your existing setup.
It is strongly recommended to secure all public remote desktop ports in your network. It is risky, outdated, and can easily be exploited.
