Intrusion possibilities with TightVNC

mehulmatrix · 02-12-2009, 09:21 PM

Hello All,
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.

Thanks,
Mehul.

Take a look at UltraVNC, which does offer encryption. There is always a "chance" of intrusion, make sure you have a complex password for the connection to make it harder for someone to breech the security.
