Best way for security

[Len]

I need to access my business computer from another location over periods
of several days duration, during which no one will be available to
physically use my computer to start the server. It seems I need to run
VNC server the entire time, leaving the computer open to potential
unintentional access.
Is there a better, meaning safer, way to do this? Is there a way to
reverse the process and run the server on the remote computer, the
viewer on my office computer, but reverse the control so I can see the
office computer not the remote? Even if this is possible, which I doubt,
is this any more secure? Any suggestions are appreciated.
