The easiest way is to go into the settings and turn off G4 WebControl. This will turn off the VNC server in the panel. Alternatively, you can set a username and password that someone would have to have in order to get into the panel.
Also unless a port is forwarded or a VPN is setup in the router any would be nefarious type person would have to be onsite connected to the LAN to even access the TP's VNC and then he/she would need the password to log in if a password is setup in the TP.
