How to detect if my network is being monitored

[S.Linus]

I would like to know if my activity over the internet is being monitored. I have some networking experience but I know very little about how VNC operates other than the software does not have to be on a Mac to monitor my activity and I only need to be on the same network.

Are there native utilities on my computer (late 2008 MacBook 10.6) that can detect network monitoring? Should I being researching other technologies, other than VNC?

Any assistance, guidance, or pointing in the right direction would be vastly appreciated.


Thanks in advance
