To ensure your remote desktop session is private:
Use strong passwords and enable multi-factor authentication (MFA).
Ensure the remote access software uses end-to-end encryption, like AES-256.
Use a VPN to add an extra layer of security when accessing a remote machine over a public network.
Disable clipboard sharing, file transfer, and other features unless necessary.
Always log out or lock the remote machine at the end of your session to prevent unauthorized access.
