We're using TightVNC for remote access from our office.
Few of concerns are:
--> When we access the clients remote system, can they be vulnerable to intrusion from the port 5900 that TightVNC is using? Similarly since we have opened a port(on the router) for this application, can similar thing happen here?
-->Are there any chances of possible virus attacks on either systems?
--> Since TightVNC doesnt provide any data encryption, can some securtity be provided without too much fuss? Cause it will be difficult to get any additional favors from the ntwk admin dept :)
Inputs will be highly appreciated.
