This is a very newbie question, but I would just like to make sure that I'm not missing anything: If I connect via VNC protocol to my various servers etc. inside my own LAN (home network), then should I consider hardening my VNC in any way? (E.g. VNC through SSH etc.). Or is it really pointless? I mean when initiating VNC connection inside the LAN means no traffic should be ever routed via public Internet anyway when I have my all VNC server applications installed locally in my servers, right? I'm using Remmina client in my Linuxs and UltraVNC servers and clients in Windows'.
I also use RDP in Windows, but RDP is already natively encrypted (though it's debatable whether enough for enterprise use), so I guess I really don't even need to worry about hardening RDP connections any further when connecting inside my LAN (I've also changed RDP default ports in my desktops).
