Chapter 7: Making Connections Secure
Under Windows, you can configure VNC Server to uphold the privacy of connected users by editing various
options in the VNC Server - Options dialog. More on this dialog.
Blanking the host computer’s monitor
You can blank the host computer’s monitor in order to prevent a host computer user observing the
operations of connected users. To do this, turn on Blank the screen while VNC Viewers are connected.
This option is on the Desktop tab.
Preventing input from the host computer
You can disable the keyboard and mouse of the host computer in order to prevent a host computer user
interrupting the operations of connected users. To do this, turn on Disable the keyboard and mouse while
VNC Viewers are connected. This option is on the Inputs tab.
Protecting the host computer
Note: The information in this section applies to VNC Server in Service Mode only.
You can protect the host computer when no connections are in progress by locking it or logging off when the
last user disconnects. To do this, select an alternative to the default Do nothing option from the When last
VNC Viewer disconnects dropdown on the Desktop tab:
To protect the host computer by:
• Locking the workstation, select Lock workstation. Users can immediately reconnect, but must know
how to unlock the host computer in order to continue. Note that if you apply this setting to VNC Server in
User Mode, users can reconnect but see only a non-operational black screen, and cannot continue.
• Logging off, select Logoff user. Users can immediately reconnect, but must know how to log on to the
host computer in order to continue.
